PLEASE DO 41 AND 45!!!!!!
Sergio [31]

Answer:

see below

Step-by-step explanation:

41

-4 ≤2+4x<0

Subtract 2 from all sides

-4-2 ≤2-2+4x<0-2

-4 ≤2+4x<0

Divide all sides by 4

-6/4 ≤4x/4<-2/4

-3/2 ≤x <-1/2

graph is attached

45

2x-3 ≤-4  or 3x+1 ≥4

Lets solve the left side first

2x-3≤-4

Add 3 to each side

2x-3+3 ≤-4+3

2x ≤-1

Divide by 2

2x/2  ≤-1/2

x  ≤-1/2

Now solve the right inequality

3x+1 ≥4

Subtract 1 from each side

3x+1-1 ≥4-1

 3x ≥3

Divide by 3

3x/3 ≥3/3

x≥1

So we have

x  ≤-1/2 or x≥1

see attached

Notice closed circles where there is a greater than equal to  or less than equal to

Mr. Lance keeps a jar of candy on his desk for students to pick from when they do well on a test. The jar contains 5 Snickers, 2
Verdich [7]
Probability = number of outcomes / total number of sample space

Number of Snickers = 5
Total number of candy = 5 + 2 + 4 + 3 = 14

Probabilty that the first student picks a Snickers = 5/14

After picking by the first student, the number of snickers reduces to 4 and the total number of candies reduces to 13

Probability that the second student also picks a Snicker = 4/13

Therefore, required probability is 5/14 x 4/13 = 20/182 = 10/91

Suppose the true proportion of high school juniors who skateboard is 0.18. If many random samples of 250 high school juniors are
madreJ [45]

Answer:

0.024

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

Suppose the true proportion of high school juniors who skateboard is 0.18.

This means that p = 0.18

Samples of 250 high school juniors are taken

This means that n = 250

By how much would their sample proportions typically vary from the true proportion?

This is the standard error, so:

s = \sqrt{\frac{p(1-p)}{n}}

s = \sqrt{\frac{0.18*0.82}{250}}

s = 0.024

So 0.024 is the answer.

Which line has an x-intercept of 4?<br> 4x + y = 8<br> -4x + y = 8<br> 2x+ 2y = -8<br> -2x + 2y = -8
Lemur [1.5K]
Answer = - 2x + 2y = - 8

Because when the x intercept is 4 the y intercept is 0 so if you put these into the equation
-2x4 + 0 = - 8
-8 = - 8

Both sides of the equation are equal
