Answer:

4/16 or .25

Step-by-step explanation:

Probability of the first being prime is 2 of 4 becasue two cards are prime

You put the card back, so the probability of the second card also being prime is also 2/4

Multiply the numerators together and then the denominators together

2*2 = 4

4*4 = 16

so the probability of picking a prime number and then picking a prime number with replacement is 4/16 or .25.

Hope this helps!

Use the values on the number line to find the sampling error.

pantera1 [17]

Part 1:

Given a number line with the point $\bar{x}=3.8$ and the point $\mu=4.27$

The sampling error is given by:

$\bar{x}-\mu=3.8-4.27=-0.47$

Part 2:

Given a number line with the point $\bar{x}=26.43$ and the point $\mu=24.67$

The sampling error is given by:

$\bar{x}-\mu=26.43-24.67=1.76$

HELP!!!!!!!!!

wel

Answer:

$y=-\frac{2}{3} x+4$

Step-by-step explanation:

move the variable to the right(-2x) and change the sign(2x now) -3y=-12+2x then change the signs (-3y is 3y , -12 is 12 and then 2x becomes -2x again) then divide both sides of the equation by 3 so 12÷3=4 and -2x÷3= $-\frac{2}{3} x$ then you're going to use the commutative property to reorder the terms . so your answer is $y=-\frac{2}{3} x+4$
