Help I need help!!! please!!!

Answer:

n = 17

[tex]\frac{n}{85}= \frac{34}{170}[/tex]

Step-by-step explanation:

[tex]\frac{n}{85}= \frac{34}{170}[/tex]

n · 170 = 34 · 85

170y = 2890

170y ÷ 170 = 2890 ÷ 170

y = 17

Answer:

He needs 1 hour 40 minutes more to get the amount of sleep he likes or 1 2/3 hours

Step-by-step explanation:

Justin likes to get 7 hours of sleep.

He woke up after sleeping for 5 1/3 hour = 5 hours 20 mins

Number of more hours needed to get the amount of sleep he likes= 7 hours - 5 1/3 hours.

1 hour = 60 minutes

1/3 hours = 60/3 = 20 minutes

Hours         Minutes

7                     00       when we borrow 1 hour we borrow 60 minutes

5                    20

1                   40

He needs 1 hour 40 minutes more to get the amount of sleep he likes

or 1 2/3 hours

Answer:

3.75 cm

Step-by-step explanation:

20 * x = 5 * 15

20x = 75

Divide both sides by 20

x = 75/20

x = 3.75

Answer:

Yes, the data provides sufficient evidence at 0.05 level of significance

Step-by-step explanation:

n = 25

s = 8

σ = 15

χ² = (n - 1)s² / σ²

χ² = (25 - 1)*8² / 15²

χ² = (24 * 64) / 225

χ² = 6.827

The critical value at 0.05 ; df = 25 - 1 = 24

12.4012 and 39.3641

Reject H0 if χ² < 12.4012 or if χ² > 39.3641

Since,

χ² < 12.4012 ; We reject H0 ;

Answer:

b. the slopes of both functions are positive

Step-by-step explanation:

hope this helps :)

Answer:

C. The slope of function A is positive and the slope of function B is negative.

Step-by-step explanation:

For this problem, you need to determine the slope of each function.

For function A:

You're given y = (1/4)x - 2/3, which is in slope-intercept form y = mx + b. The slope of an equation in slope intercept form is given by m.

So the slope for function A is 1/4.

For function B:

You're given a list of (x, y) points, so use the definition of the slope = [tex]\frac{y2-y1}{x2-x1}[/tex], which gives you the slope from any two (x, y) points on the line. Let's take the first and second points (2, -8) and (4, -9)

Slope = [tex]\frac{-9-(-8)}{4-2} = \frac{-1}{2}[/tex].

Therefore, the slope of function A is positive and the slope of function B is negative.

Answer:

integer

Step-by-step explanation:

the slope looks like it's 4/1 when simplified it's 4. (integer)

Answer:

The slope is the integer 4

Step-by-step explanation:

take the points (-2, -9) (-1, -5) and put them in the formula  y2 - y1 over x2 - x1 and you get m = 4

We know that:

Slope of a line = change in y coordinate / change in x coordinate

We are given:

First point = (2,5)

Second point = (5, 14)

Calculating the change in y coordinate:

change in y (also represented by Δy) = second y - first y

Δy = 14 - 5

Δy = 9

Calculating the change in x coordinate:

Δx = second x - first x

Δx = 5 - 2

Δx = 3

Slope of the line:

Slope = (Δy) / (Δx)

Slope = 9 / 3                                              [replacing the values]

Slope = 3

Answer: x>5

Answer:

Elena’s MAD:  2

Step-by-step explanation:

 24  ÷ 12 = 2

Answer:

Circumference = diameter × π

Take π =3. 14

Answer:

Alright, with this, its essentially asking for you to plug in X into each equation for the answer.

With the first box, it asks for y = 5 - x, given the x = -2.

y = 5-x

y=5-(-2)

y=5+2

y=7

With the second box down, it wants things a bit differently, it gives you the y value, and wants for you to find the x. Given this, this question can be done backwards for the x value.

y = 5-x

6 = 5-x

x+6= 5

x=-1

With the third one, its the same thing as with the first box.

y = 5-x

y = 5-0

y = 5

Same thing with the fourth one.

y = 5-1

y = 4

Answer:

$0.22 per foot

Step-by-step explanation:

So for context, 1 yard is 3 feet. So 2 yards is 6 feet. With this, by dividing $1.32 by 6, you can get the price per foot:

1.32 / 6 ---> $0.22 per foot.

Answer:

Landing on Blue: Likely

Landing on Green: Impossible

Landing on Yellow: Unlikely

Step-by-step explanation:

Blue: 50% chance

Green: 0% chance

Yellow: 12.5% chance

Answer:

So blue is 4/8 which should be as likely as not then red is 3/8 could be unlikely since it is 38 percent. then yellow is for sure unlikely since it is just 1/8
