The y-intercept of the function F(x) = x⁴ + 2x - 2 is -2 and the profile is matched to the given graph thus option (B) is correct.
What is a graph?The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.
For example plot of y = x³ ,y = sinx.
As per the given graph of the function,
In option (B),
F(x) = x⁴ + 2x - 2
Put x = 0
F(0) = 0 + 0 - 2 = -2
Thus, (0,-2) will be the y-intercept which is matching in the graph.
Hence "The y-intercept of the function F(x) = x⁴ + 2x - 2 is -2 and the profile is matched to the given graph".

The entire missing lengths as well as the missing angles of the given right angle triangle are as calculated below using Pythagoras theorem and trigonometric rules.
How to use trigonometric rules?We are given a right angle triangle and as such we can use both Pythagoras theorem and even trigonometric rules such as sine rule and cosine rules.
a) W are given that A = 30°, Thus;
B = 180 - (90 + 30)
B = 60°
Using sine rule;
a/sin A = b/sin B
a/sin 30 = 6/sin 60
a = 3.464
c/sin 90 = 6/sin 60
c = 6.928
b) a = 13 and b = 13
Using Pythagoras theorem;
c = √(13² + 13²)
c = 18.385
Since a = b, it means it is an isosceles triangle and so;
A = B = 45°
c) B = 30°, c = 10
A = 180 - (30 + 90)
A = 60°
10/sin 90 = b/sin 30
b = 5
10/sin 90 = a/sin 60
a = 8.66
d) A = 45°, c = 12
B = 45°
c/sin 90 = b/sin 45 = a/sin 45
b = a = 12 * sin 45 = 8.485
e) c = 1, b = 1/√2
c/sin 90 = b/sin B
1/sin 90 = (1/√2)/ sin B
B = 45° = A
a = √(1² - (1/√2)²)
a = 0.7071
f) c = 4 and b = 4;
a = √(4² - (4)²)
a = 0

Suppose a researcher is testing someone to see whether she or he can tell Soda X from Soda Y, and the researcher is using 34 trials, half with Soda
X and half with Soda Y. The null hypothesis is that the person is guessing.
a. About how many should the researcher expect the person to get right under the null hypothesis that the person is guessing?
b. Suppose person A gets 24 right out of 34, and person B gets 20 right out of 34. Which will have a smaller p-value, and why?
a. The person should get right.
(Type a whole number.)
b. Person
will have a smaller p-value because
a. The researcher should expect each person to get 17 guesses correct under the null hypothesis that the person is guessing.
b. Person A has a smaller p-value because the person's number of successes is further to the hypothesized number of successes.
What are the hypothesis tested?At the null hypothesis, it is tested if the person is guessing, that is, if the proportion is of 0.5, hence:
[tex]H_0: p = 0.5[/tex]
At the alternative hypothesis, it is tested if there is enough evidence to conclude that the person is not guessing, that is, if the proportion is different than 0.5, hence:
[tex]H_0: p \neq 0.5[/tex]
Considering the tested proportion of 0.5, the expected number of correct guesses on the 34 trials is of:
0.5 x 34 = 17 correct guesses.
What are the test statistic and the p-values?The test statistic is given by the equation presented as follows:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.The parameters that are the same for each person are given as follows:
[tex]p = 0.5, n = 34[/tex]
The sample proportions are given as follows:
Person A: 24/34 = 0.7059.Person B: 20/34 = 0.5882.Then the test statistics are given as follows:
Person A: z = (0.7059 - 0.5)/sqrt(0.5 x 0.5/34) = 2.40.Person B: z = (0.5882 - 0.5)/sqrt(0.5 x 0.5/34) = 1.03.Person A is farther from the mean due to the higher test statistical, hence it has a smaller p-value.

Jenny collected donations at a pet store for the local animal shelter. As she left, Jenny
estimated she had collected $85. After counting the donations, she learned she had actually
collected $110. What is the percent error for her estimate?
If necessary, round your answer to the nearest tenth of a percent.
Answer:
Step-by-step explanation
Initial amount = $85
Final amount = $110
percentage error = ((Final amount - Initial amount)*100)/Final amount
= (25*100)/110
=22.7272
=22.7 (to the nearest tenth of a percent, which is 1 decimal place)
The solution is 22.7 %
The percentage error in the estimation of donations at the pet store by Jenny is 22.7 %
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
Let the percentage error be represented as A
Now , the value of A is
The estimated donation amount by Jenny = $ 85
The actual donation amount collected by Jenny = $ 110
Now , the percentage error in the estimation of Jenny A is calculated by the equation ,
Percentage error in the estimation of Jenny A = ( ( | estimated donation amount - actual donation amount collected by Jenny ) | / actual donation amount collected by Jenny ) ) x 100
Substituting the values in the equation , we get
Percentage error in the estimation of Jenny A = ( | 85 - 110 | / 110 ) x 100
On simplifying the equation , we get
Percentage error in the estimation of Jenny A = ( 25/110 ) x 100
Percentage error in the estimation of Jenny A = 2500 / 110
Percentage error in the estimation of Jenny A = 22.72 %
Therefore , the value of A is 22.7 %

In scientific notation, the amount of paper used weekly by the Pittsburgh paper is approximately 5.0 x 10⁷ times more than the amount used by the Newville paper.
What is scientific notation?Scientific notation is a shorthand or approximated way to write large or small numbers.
Scientists use scientific notations to eliminate the many zeros in a number so that the number is written in a standard form.
In scientific notation, a positive integer is multiplied by another integer (positive or negative) in the power of ten.
The best way to compute the ratio of paper usage at the two newspapers is to rewrite the numbers in long form and convert the answer to scientific notation.
Location Paper Used (square yards)
Newville 8.0 x 10³ = 8,000
Pittsburgh 4.0 x 10¹¹ = 400,000,000,000
The ratio of Pittsburgh to Newville = 8,000:400,000,000,000

= 1: 5.0 x 10⁷
We can also divide 400,000,000,000 by 8,000 to get 50,000,000, which can then be written in standard form as 5.0 x 10⁷.

The amount after 5 years will be $____.
(Do not round until the final answer. Then round to the nearest cent as needed.)
The total amount the college student will have in the savings account after 5 years will be $15,095
Compound interest: Calculating amount in a savings accountFrom the question, we are to determine the amount the college student has in savings.
From the compound interest formula, we have that
A = P(1 + r/n)^nt
Where A is the amount
P is the principal
r is the interest rate
n is the number of times compounded per year
and t is the time.
From the given information,
P = $13,000
r = 3%= 0.03
n = 4
t = 5
Putting the parameters into the formula
A = P(1 + r/n)^nt
A = 13000(1 + 0.03/4)^(4×5)
A = 13000(1 + 0.03/4)^20

What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.
Using the equation for a straight line and writing similar
h = mt + c
h = height, t = hours m and c are constants
at h = 24, t = 4
Equation becomes
24 = 4m + c--------------1
at h = 20, t = 6
20 = 6m + c---------------2
Subtract equation 2 from 1 so that the eqution reduces to
4 = -2m
m = 4/-2
m = -2
substitute m in equation 1
24 = 4( -2) + c
24 = -8 + c
c = 32
substituting m and c in he linear equation above we have
h = 32 - 2t
After 8 hours, the height h = 32 -2(8) which is 16 inches
In conclusion the linear equation is h = 32 - 2t and the height of fire after 8 hours is 16 inches

Apple pie is my favorite. I bake a
lot of it because I never got my
fair share as a kid. Last year i
got a little carried away and
had 7 pies left over. I cut the
pie into pieces to freeze and
save for later. Each piece was
of a whole pie. How many
pieces of pie did I freeze?
Answer:
58
Step-by-step explanation:
You would have to turn 7 1/4 into a whole fraction.
Do,
7 * 4 = 28
28 + 1 = 29
Your new fraction would be,
29/4
Now you have to make them equal denominators with 1/8.
Lets see,
Now multiply 4 * 2 is 8.
So multiply 29 times 2.
Which is 58.
Your new fraction is,
58/8
So therefore you would have 58 pieces.
