Answer 1
When we use this = it means it is the exact
answer
When we use ≈ it means it is an estimated answer and not the exact answer Example 12.4684729572974729758328 ≈ 12

A certain shade of pink us created by adding 3 cups of red paint to 7 cups of white paint

Answers

Answer:

A certain shade of pink us created by adding 3 cups of red paint to 7 cups of white paint

Step-by-step explanation:

Constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.

To make color pink,

for every 3 cups of red , we need 7 cups of white.

Let 'r' be the cups of red required

let 'w' be the cups of white required

so , as per the question

for 3 r we need = 7 w

r = 7/3 w

so, 7/3 is constant of proportionality

y = -21 – 4x

Answers

Answer:
x=-6
y=3

Explanation:
y=-4x-21
8x+8y=-24

y=-4x-21
8x+8(-4x-21)=-24

y=-4x-21
-24x-168=-24

y=-4x-21
x=-6

y=-4(-6)-21
x=-6

y=3
x=-6

A soccer player practices kicking the ball into the goal from halfway down the soccer field. The time it takes for the ball to get to the goal from the time it is kicked averages about three seconds. The soccer field is 90 meters long. The player wants to know the average velocity of the ball.

Is there enough information to calculate this?


A: No, only average speed can be calculated from the distance of 90 meters and the time of three seconds.

B: No, only average speed can be calculated from the distance of 45 meters and the time of three seconds.

C: Yes, displacement is 45 meters, elapsed time is three seconds, and the direction is toward the goal.


D: Yes, displacement is 90 meters, elapsed time is three seconds, and the direction is toward the goal.

Answers

Answer: D

Step-by-step explanation:

the distance is 90m and the time is max 3 to goal so the answer is D

negative 2 times left parenthesis 6 plus s right parenthesis is greater than or equal to negative 15 minus 2 s

Answers

-2 ( 6 + s ) >_ -15 - 2s

We distribute the left side of the inequality.

-12 - 2s >_ -15 - 2s

Add 2s on both sides.

They cancel out, and we’re left with:

-12 >_ -15

This is surprisingly a true statement, so s = 0 in order for us to end up with this again.

Hopefully it’s right. Good luck!

What is the discriminant of the equation 3x^2-4=2x

Answers

Answer :

Given equation : 3x² - 4 = 2x

We have to find discriminant of the equation [tex].[/tex]

⭆ 3x² - 4 = 2x

⭆ 3x² - 2x - 4 = 0

By comparing this equation with ax²+bx+c, we get

a = 3b = -2c = -4

Discriminant (D) = b² - 4ac

⭆ D = (-2)² - 4(3)(-4)

⭆ D = 4 + 48

D = 52

(6 pts) a) Identify the variable of interest. b) Describe the center and spread of the population of Sunshine City. c) Describe the center and spread of the random sample of Sunshine City residents taken. What shape does it probably have

Answers

Answer:

a) Identify the variable of interest.

Ages of the residents

b) Describe the center and spread of the population of Sunshine City.

Center of the population of Sunshine city = 63 years

Spread of the Population of Sunshine city = 17 years

c) Describe the center and spread of the random sample of Sunshine City

residents taken.

Center of the random sample of Sunshine city = 61.4 years

Spread of the random sample of Sunshine city = 19 years

What shape does it probably have:

It has a skewed(left) shape

Step-by-step explanation:

a) Identify the variable of interest.

Ages of the residents

The center of a distribution tells us about the Mean or Median of the distribution

The spread of a distribution tells us about the standard deviation of the population

b) Describe the center and spread of the population of Sunshine City.

Center of the population of Sunshine city = Mean of the population of Sunshine city = 63 years

Spread of the Population of Sunshine city = Standard Deviation of the population = 17 years

c) Describe the center and spread of the random sample of Sunshine City

residents taken.

Center of the random sample of Sunshine city = 61.4 years

Spread of the random sample of Sunshine city = 19 years

What shape does it probably have:

It has a skewed(left) shape

This is because the mean is farther out to the left side of the tail of the distribution.
