Complete question :

The IQ scores of the middle 50% of a population can be written as (x - 100) / 15 ≤ 2/3

Answer: 90 ≤ x ≤ 110

Oxs 90 and x 2 110

Step-by-step explanation:

Given the inequality:

The middle 50% of the population :

(x - 100) / 15 ≤ 2/3

The upper bound :

(x - 100) / 15 ≤ 2/3

multiply both sides by 15

(x - 100) / 15 * 15 ≤ 2/3 * 15

(x - 100) ≤ 2/3 * 15

x - 100 ≤ 10

x ≤ 10 + 100

x ≤ 110

The lower bound :

- (x - 100) / 15 ≤ 2/3

(-x + 100) / 15 ≤ 2/3

multiply both sides by 15

(-x + 100) / 15 * 15 ≤ 2/3 * 15

(-x + 100) ≤ 2/3 * 15

-x + 100 ≤ 10

-x ≤ 10 - 100

-x ≤ - 90

x ≤ 90

90 ≤ x ≤ 110

Answer:

-2/3

Step-by-step explanation:

Rise: 4

Run: -6

Slope = Rise over run

Slope = 4 / -6

4 / -6 = -2/3

Answer:left is 7 right is 6

Step-by-step explanation:

left is 7 right is 6

Answer:

the right side is 6 and the left side is 7

Step-by-step explanation:

These triangles are similar. Since the bottom side goes from 15 to 5, that means you divide the other 2 sides by 3 also.

Answer:

y = -2x+7

Step-by-step explanation:

equation of line formula:

[tex]y = mx + c[/tex]

m = slope, c = y-intercept

1) find the slope using the given coordinates

slope formula:

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

i) (3,1)

x1=3

y1=1

ii) (7,-7)

x2=7

y2=-7

substitute the values into the formula

[tex]m = \frac{ - 7 - 1}{7 - 3} [/tex]

[tex]m = \frac{ - 8}{4} [/tex]

[tex]m = - 2[/tex]

so now half of the equation is complete as we have the the value of m. substitute the value of m into the slope formula.

[tex]y = - 2x + c[/tex]

2) find the value of c

to find the value of c, we must substitute either coordinate into the half equation. so, i choose the coordinate (3,1). if you substitute the coordinate (7,-7) , you will get the same value of c.

(3,1)

x = 3

y = 1

[tex]y = - 2x + c[/tex]

[tex]1 = - 2(3) + c[/tex]

[tex]1 = - 6 + c[/tex]

[tex]1 + 6 = c[/tex]

[tex]c = 7[/tex]

substitute the value of c into the half equation and that is your straight line equation

[tex]y = - 2x + 7[/tex]

Answer:

b0 = 5.83

b1 = 52.23

Step-by-step explanation:

Given the data:

X:

2

4

5

6

Y

70

65

78

95

General form of a linear regression equation :

y = b1x + b0

b1 = slope ; b0 = intercept

Using an online regression calculator, the regression equation obtained is :

y = 5.8286 + 52.2286x

Comparing the equation ;

b1 = 52.23

b0 = 5.83

Answer:

4833 m

Step-by-step explanation:

Given that her angle of elevation at the first recording is 47.3 at an altitude of 4900 m

We use Pythagoras Theorem to get this done

We can say that the opposite of the angle is the altitude, while the hypotenuse of the triangle, is the distance between herself and the top

Using the sine angle rule, we have

Sine 47.3 = 4900 / h

h = 4900 / sin 47.3

h = 4900 / 0.7349

h = 6668 m

This means that she was 6668 m away from the top of the mountain

She then moves 1000 m closer to the mountain top, this means that our h = 6668 - 1000

Using the same sine angle rule, we have

Sine 58.5 = o / 5668

o = 5668 * sine 58.5

o = 5668 * 0.8526

o = 4833 m

She is 4833 m above the sea level

Answer:

[tex]S= 4[/tex]

Step-by-step explanation:

Given

[tex]Total = 20[/tex]

[tex]Selection = 5[/tex]

Required

Determine the size of sample space

Represent this with S

S is calculated by dividing the total number of kids by the number of selection.

[tex]S = \frac{Total}{Selection}[/tex]

[tex]S = \frac{20}{5}[/tex]

[tex]S= 4[/tex]

Hence, the sample space has a size of 4

Answer:

1

Step-by-step explanation:

anything raised to the power of 0 would equal 1 and p doesn't equal 1 here.

Answer:

4 or 0

Step-by-step explanation:

well if the variable p became 0 the term 4p would look more like this 4(0) or   4 * 0 making the answer be 0

If the variable was changed into 1 the term 4p would become 4(1) or 4 * 1 as of such the answer would be 4.

now if you are raising p to a 0 so the term is more like this: 4p to the power of 0 then your answer would be 1. Because p would change to 0.

Now if you had 4p to the raised power of 1 then your answer would be 4 because p was changed to a 4.

I hope this answers your question.

Answer:

It should take Joey 3 hours to jog to the store.

Step-by-step explanation:

For this problem, 0.25 in = 50 m. So

11 in = (11 in) • (50/0.25 m/in) = 2200 m

Alternatively, if 0.25 in = 50 m, that means 1 in = 200 m. So 11 in = 11 (200 m) = 2200 m.
