Answer:

96 marks

Step-by-step explanation:

We know that the mean of a given amount of values is the sum of the values divided by the number of values

Let the marks in the fourth test = x marks

Mean of the values = 90

(85 + 90 + 89 + x) / 4 = 90

264 + x = 360

x = 96

Therefore, Jamie needs 96 marks in her 4th test to get a mean score of 90

Answer:

  see below

Step-by-step explanation:

The slope is given as 6/7. In slope-intercept form that is the coefficient of x, eliminating choices C and D.

If we try the point in the remaining equations, we find ...

  A: y = 6/7(6) -1/7 = (36 -1)/7 = 35/7 = 5 . . . . . the correct equation

  B: y = 6/7(6) +1/7 = (36+1)/7 = 37/7 = 5 2/7 . . . does not match (6, 5)

The appropriate choice is A.

Step-by-step explanation:

Hey there!

Given;

The measure of angle B is 45°.

And AB = 14.

Taking refrence angle as B, we get;

AC = perpendicular

AB = hypotenuse

Using ratio of sin,

[tex] \sin(45°) = \frac{p}{h} [/tex]

Put all values.

[tex] \sin(45°) = \frac{ac}{14} [/tex]

Simplify it to get answer.

[tex] \frac{1}{ \sqrt{2} } = \frac{AC}{14} [/tex]

[tex] \sqrt{2} AC = 14[/tex]

[tex]AC = \frac{14}{ \sqrt{2} } [/tex]

[tex]AC= \frac{14 \times \sqrt{2} }{ \sqrt{2} \times \sqrt{2} } [/tex]

[tex]AC = \frac{14 \sqrt{2} }{2} [/tex]

[tex]AC = 7\sqrt{2} [/tex]

Therefore the answer is option B.

Answer:

A. 4 ounces

Step-by-step explanation:

Given that Elana paid $2.50 for 10 ounces of popcorn, let x be the amount popcorn a dollar will buy.

Thus we have:

$2.50 = 10 ounces

$1 = x

Cross multiply

$2.50 × x = 10 ounces × $1

Divide both sides by $2.50

($2.50 × x)/$2.50 = (10 ounces × $1)/$2.50

x = (10 ounces)/2.50

x = 4 ounces

Therefore, you can buy 4 ounces of popcorn per dollar

Q10 --Option --- (B) RECTANGLE

Step-by-step explanation:

Q9 --

we know area of triangle  = 1/2 ab sin theta

Where theta is the angle included between sides A and side B

A  = 5.2

B = 7

theta  = 121 degrees

1/2 * 5.2 * 7 * sin 121 degrees = 15.6 Square Units

Conclusion

The area of the triangle is 15.6 Square Units

Answer:

a. [tex]Mean = 8.25[/tex]

b. [tex]SD = 3.7125[/tex]

c. [tex]SD = 3.15[/tex]

d. [tex]SD = 2.4[/tex]

e. As p approaches 1 , the standard deviation increases (that is, it approaches 0).

Step-by-step explanation:

Solving (a):

[tex]p = 55\%[/tex]

[tex]n = 15[/tex]

Find Mean

Mean is calculated as thus:

[tex]Mean = n * p[/tex]

[tex]Mean = 15 * 55\%[/tex]

Convert percentage to decimal

[tex]Mean = 15 * 0.55[/tex]

[tex]Mean = 8.25[/tex]

Solving (b):

Calculate Standard Deviation (SD)

Standard deviation is calculated as thus:

[tex]SD = n * p * (1 - p)[/tex]

[tex]SD = 15 * 55\% * (1 - 55\%)[/tex]

Convert percentage to decimal

[tex]SD = 15 * 0.55 * (1 - 0.55)[/tex]

[tex]SD = 15 * 0.55 * 0.45[/tex]

[tex]SD = 3.7125[/tex]

Solving (c):

Calculate Standard Deviation if p = 0.7

Using same formula used in (b) above

[tex]SD = n * p * (1 - p)[/tex]

[tex]SD = 15 * 0.7 * (1 - 0.7)[/tex]

[tex]SD = 15 * 0.7 * 0.3[/tex]

[tex]SD = 3.15[/tex]

Solving (d):

Calculate Standard Deviation if p = 0.8

Using same formula used in (b) & (c) above

[tex]SD = n * p * (1 - p)[/tex]

[tex]SD = 15 * 0.8 * (1 - 0.8)[/tex]

[tex]SD = 15 * 0.8 * 0.2[/tex]

[tex]SD = 2.4[/tex]

Solving (e):

What does the working show

In (b)

When p = 0.5

SD = 3.7125

In (c)

When p = 0.7

SD = 3.15

In (d)

When p = 0.8

SD = 2.4

Notice that as the value of p increases, the standard deviation gets closer to 0.

Answer:

see below

Step-by-step explanation:

First we need to find the slope

m = ( y2-y1)/(x2-x1)

   = ( 5-3)/(-1-7)

   = 2/-8

   = -1/4

Point slope form is

y-y1 = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

y -3 = -1/4( x-7)

or using the other point

y -5 = -1/4( x--1)

y -5 = -1/4( x+1)

Step-by-step explanation:

3.00 x 44 = 132

Answer:

This is a sidenote. Sometimes, I give you the expression to find the answer, you just have to calculate it.

Answer:   Infinitely many solutions

Answer:  

The ratio simplifies fully to 2:1

=======================================================

Work Shown:

4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5

2 & 1/4 = 2 + 1/4 = 2 + 0.25 = 2.25

The original ratio is the same as 4.5 : 2.25

Divide both parts by 2.25 and you'll end up with 2:1

4.5/2.25 = 2

2.25/2.25 = 1

This means the length is twice as long compared to the width.

Answer:

x=7

Step-by-step explanation:

thats the answer

Answer:

A. 76

B. x^2 +21x + 96

C. x^2 - 9x + 6

Step-by-step explanation:

For this problem, just plug in the number in f(x) for x in the function.

A. f( 5 ) -> Plug in 5 for every x and then simplify

(5)^2 + 9(5) + 6

= 25 + 45 + 6

= 76

B. f( x+6 ) -> Plug in (x+6) for every x and then simplify

(x+6)^2 + 9(x+6) + 6

x^2 + 12x +36 + 9x+ 54 + 6

x^2 +21x + 96

C. f( -x ) -> Plug in -x for every x and then simplify

(-x)^2 + 9(-x) + 6

x^2 - 9x + 6

Answer: x=9/4

Step-by-step explanation:

combine like terms then

4x+7=16

4x=9

x=9/4 or 2.25

2x -x + 9 +3x -2 = 16

COMBINE LIKE TERMS

2x- x + 3x =4x    9 -2=7

4x+7 = 16

4x +7 -7 = 16 -7

4x = 9

4x/4 = 9/4

x = 2.25 or 2 1/4

Answer:

-2 and suki was right aDriene was wrong as he added

Step-by-step explanation:

-8-(-6)

-8+6        (it becomes positive 6 as a negative and negative give u a positive )

= -2

The Suki answer is correct and the correct answer is -2.

It is required to find the error.

An expression is a set of terms combined using the operations +, – , x or ÷. An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An expression is in simplest form when no terms can be combined

Given:

Adrienne and Suki simplified the expression -8 -(-6)

We have to find the error was made by Adrienne or Suki .

The expression is

-8 -(-6)

Open bracket we have and both minus sign is multiply to get a plus sign as a result, we get

=-8+6

=-2

The correct answer is -2.

Therefore, the Suki answer is correct and the correct answer is -2.
