An exam consists of 50 multiple choice questions. Based on how much you studied, for any given question, you think you have a probability of 0.64 of getting the correct answer. Consider the sampling distribution of the sample proportion of correct questions out of 50. (a) Find the mean and standard error of the sampling distribution of this proportion; (b) What do you expect for the shape of this sampling distribution? - approximately normal because n is large; - cannot be determined because p is greater than 0.5; - cannot be determined because n is large; - approximately normal because the population is normal.

Answers

(a) The mean is 32, and the standard error is 0.068 (b) The expected shape will be approximately normal (c) The probability of scoring less than 60% is 0.278

As the number of questions (n) is 50 and the probability of getting the correct answer (p) is 0.64, the mean can be calculated as follows;

E(x) = np

E(x) = 50 × 0.64

E(x) = 32

The standard error is calculated as follows;

SE = √p×(1-p) ÷ n

SE = √0.64 × (1-0.64) ÷ 50

SE = √0.004608

SE = 0.068

Therefore, the mean is calculated to be 32, and the standard error is 0.068

As the sample size is large therefore the expected shape will be approximately normal

To calculate the probability of scoring less than 60%, we first calculate the z-score using:

z = (x – μ) / σ

z = (0.60 - 0.64) / 0.068

z = -0.588

So we have;

P (x < 60%) = P (z < -0.588)

P (x < 60%) = 0.278

Therefore the probability of scoring less than 60% is 0.278

Chad is planning a 672–mile road trip. • Chad’s car can travel 308 miles with 11 gallons of gas. • Chad plans to drive 168 miles every 3 hours. How many hours will it take Chad to drive 672 miles, and how many gallons of gasoline will he need?

Answers

It will take Chad 12 hours to drive 672 miles and he will need 24 gallons of gasoline

How to calculate many hours will it take Chad to drive 672 miles?

Given that: Chad is planning a 672–mile road trip

Chad’s car can travel 308 miles with 11 gallons of gas. We can use this information to calculate the miles 1 gallon can cover. Thus:

Number of miles per gallon =   308/11 = 28 miles per gallon

Also, Chad plans to drive 168 miles every 3 hours. We can use this information to calculate Chad's speed. Thus:

Speed = 168/3 =  56 miles per hour

To determine how many hours it will take Chad to drive 672 miles:

Speed = distance/time

=> time = distance/speed    

Speed = 56 miles per hour and distance =  672 miles

time = 672/56 = 12 hours

Number of gallons = distance / Number of miles per gallon

Number of gallons = 672/28 = 24 gallons

Therefore, it will take Chad 12 hours to drive 672 miles and he will need 24 gallons of gasoline

Which is an example of system of linear inequalities?.

Answers

Example of  linear inequalities; y ≤ x – 1 and y < –2x + 1

A combination of linear inequality equations with the same variables is referred to as a system of linear inequalities.

There are five inequality symbols used to represent equations of inequality.

These are less than (<), greater than (>), less than or equal (≤), greater than or equal (≥), and the not equal symbol (≠). Inequalities are used to compare numbers and determine the range or ranges of values that satisfy the conditions of a given variable.

Example of  linear inequalities;

Graph the following system of linear inequalities:

y ≤ x – 1 and y < –2x + 1

Graph the first inequality y ≤ x − 1.

We will draw a solid border and shade below the line due to the "less than or equal to" mark.

On the same x-y axis, graph the second inequality, y -2x + 1.

In this instance, the less-than symbol will cause our boundaries to be dashed or dotted. Under the border, cast a shade.

As a result, the darker-colored zone extending indefinitely downward is the solution to this inequality problem, as seen below.

How do you tell if a graph is an exponential function?.

Answers

An exponential function is a mathematical function in which the output of the function increases (or decreases) at a rate that is proportional to the current value of the output.

Exponential functions have an “asymptote”, which is a line that the graph approaches but never crosses. This asymptote is often a horizontal line, and it can be used to identify exponential functions.

To determine if a graph is an exponential function, look for a curve that rises or falls steeply and then levels off. The curve should be smooth and symmetrical, and the points should lie along a straight line when plotted on a logarithmic scale. The equation for the graph should also have an exponential form, such as y=ab^x. If these characteristics are present, then the graph is an exponential function.

Annie was given two pieces of information and must write the equation of a line. She knows the line crosses the y-axis at the point (0,6) and has a slope of 7. What is the equation of the line?.

Answers

The equation of the line is y = 7x + 6 when  the line crooses the y-axis at the point (0,6) and has a slope of 7

The line crosses the y-axis at the point (0,6)

The slope of the line is 7

The equation of a line in slope point form is

y - y' = m(x - x')

Where m stands for the slope of the line and x' y' are the coordinates of the point through which the line passes.

So, the point x',y' is 0, 6 and the slope m is 7

y - y' = m(x - x')

y - 6 = 7 (x - 0)

y - 6 = 7x

y = 7x + 6

Therefore, the equation of the line which  crosses the y-axis at the point (0,6) and has a slope of 7 is y = 7x + 6

Answers

The equation of the line that passes through (1, 2) and is parallel to the line whose equation is 4x + y - 1 = 0 is  4x+y-6=0.

What is meant by slope-intercept form?

The line's equation is expressed in slope-intercept form: y = mx + b, where m represents the slope and b represents the y-intercept.

The slope intercept form is used to calculate the y-intercept and slope of a straight line.

We know that the equation of the line is, y= mx +b

4x+y-1=0 is the same as y= -4x+1

For this equation, b=1, but for a line with slope -4 passing through the point (1,2), the y-intercept changes.

y= -4x+b

The above line is passing through the point (1, 2)

2=-4(1)+b

Now, we have to solve for b value we get b=6.

The equation that we get is,

y= -4x+6 or 4x+y-6=0.

4s2 4p1 - electronic configuration corresponds to gallium

Periodic table has 4 different blocks, which are s block, d block, p block, and f block. Each block has corresponding elements which gives its electron configuration

What is group and period?

The systematic arrangement of elements in increasing order of their atomic numbers.Periodic table has 18 groups and 7 periods.The horizontal rows are known as periods.And the vertical columns are known as groups.

Prediction of Period ⟶ In electronic configuration of an atom, principal quantum number (n) of valence electrons represents the period of an element.

Prediction of Block ⟶ The orbital out of s,p,d and f which receives last electron represents block of an element

Prediction of Group ⟶ The group prediction occurs with help of block as:-

(1) For s block: Group Number = Number of valence e-

(2) For d block: Group Number = Number of e- in (n−1)d subshell + number of e- in ns subshell

(3) For p block: Group Number = Number of valence

e- + 10

(4) For f-block: Group Number = 3

Lets take an ex of chlorine ( Z= 17 )

Electronic configuration = 1s2 2s2 2p6 3s2 3p5

Since the last e- enters in p - subshell:

(i) Therefore Block will be "p "

(ii) For group we have element in p-block

∴ Group number = 10 + Valence e- in s subshell + Valence e- in p subshell

Group Number = 10+2+5=17

(iii) For period

Quantum number of valence e- =3

∴ Period number = 3

Which expressions are equivalent to the given expression. Square root of 252
A. 126^1/2
B. 7•square root of 6
C. 18•square roof of 7
D. 6•square root of 7
E. 252^1/2

Answers

Answer:

D

E

Step-by-step explanation:

Prime factorize 252.

252 = 2 * 2 * 3 * 3 * 7

[tex]\sf \sqrt{252}=\sqrt{2*2*3*3*7}[/tex]

        [tex]\sf = 2*3\sqrt{7}\\\\=6\sqrt{7}[/tex]

D

[tex]\sf \text{The exponent form of } \ \sqrt{252}=252^{\frac{1}{2}}[/tex]

E

Step-by-step explanation:

so, first, let's see the factors of 252 :

252 / 2 = 126

126 / 2 = 63

63 / 2 no

63 / 3 = 21

21 / 3 = 7

so, 252 = 2×2×3×3×7 =

= 4×9×7 =

= 36×7 =

= 42×6 =

= 18×14

and others. but these are closest to the given answer options.

A. is wrong. 126^(1/2) is the same as sqrt(126). that is of course not the same as sqrt(252).

B. is wrong. to leave 6 in the square root, the remaining factor is 42. and sqrt(42) is not 7.

C. is wrong. to leave 7 in the square root, the remaining factor is 36. and sqrt(36) is not 18.

D. is correct. see C. sqrt(36) = 6. so, sqrt(252) = sqrt(36×7) = 6×sqrt(7).

E. is correct. 252^(1/2) is exactly the same as sqrt(252). an exponent of 1/n means the nth root.

abe, bobby, charles, devin and edwin are the participants in a race. how many different $1$st-$2$nd-$3$rd place outcomes are possible if there are no ties? two different outcomes to include are bobby-devin-edwin and devin-bobby-edwin.

Answers

We apply permutation formula to the number of participants considering that there are no ties and find out that there are 60 different outcomes possible if there are no ties.

It is given to us that -

There are 5 participants - Abe, Bobby, Charles, Devin, and Edwin

We have to find out the number of different 1st - 2nd - 3rd place outcomes that are possible if there are no ties.

Considering that there should be no ties,

If we select one person, say Abe, then there are 4 different ways remaining for the second place in the race.

Similarly, assuming that Abe ranked 1st in the race and Bobby ranked 2nd in the race, there are 3 different ways remaining for the third place in the race.

Continuing like this, the 5 different participants can be ranked accordingly such that there are no ties.

For this situation, we have to find the permutation where -

Total number of objects (in this case, participants) = n = 5

and, total number of objects selected = r = 3

We know that the formula for permutation is -

[tex]P = \frac{n!}{(n-r)!}\\[/tex]

Substituting the values of 'n' and 'r' in the above equation, we have

[tex]P = \frac{n!}{(n-r)!}\\= > P = \frac{5!}{(5-3)!}\\= > P = 60[/tex]

Thus, by applying permutation formula, we find out that there are 60 different outcomes possible if there are no ties.

a triangle has two sides of length 5 and 9. what compound inequality describes the possible lengths for the third side, x?

Answers

The compound inequality describes the possible lengths for the third side, x is -4< c< 14.

What is meant by triangle?

A triangle is a three-sided polygon that is sometimes (but not always) referred to as a trigon. Every triangle has three sides and three angles, with some of them being the same.

A triangle with A, B, and C vertices is symbolized by ΔABC

The Triangle Inequality Theorem states that given two triangle side lengths, the length of the third side must be greater than the difference and less than the sum of the two provided sides. The third side c of a triangle must be the same as the first two sides a and b:

(a - b) < c < (a + b)

As a result, let a = 5 and b = 9

(5-9) <c (5+9)

-4< c< 14

As a result, the third side of the triangle must follow the inequality, which is -4< c <14
