Answer:

D. The function indicates that the group began with 40 members and is increasing in size.

Step-by-step explanation:

The graph shows that on the y-axis, which starts with 40, the values of the members are increasing in size. The line is going up and not down so it's increasing.

An expression that is equivalent to 20x^4

Veronika [31]

An expression that is equivalent to $20x^4$ is 5 $x^{2}$ × 4 $x^{2}$ or 10 $x^{1}$ ×2 $x^{3}$

Step-by-step explanation:

We can write the equivalent expression for the given expression as,

5 $x^{2}$ × 4 $x^{2}$ = 20 $x^{2+2}$ = 20 $x^{4}$

We can add the powers of x as 2+ 2 = 4.

Since the base x is same we can add the powers as per the law of exponents as, $x^{m}$ × $x^{n}$ = $x^{m+n}$

10 $x^{1}$ ×2 $x^{3}$ = 20 $x^{1+3}$ = 20 $x^{4}$

So an expression that is equivalent to $20x^4$ is 5 $x^{2}$ × 4 $x^{2}$ or 10 $x^{1}$ ×2 $x^{3}$

A well-mixed cookie dough will produce cookies with a mean of 66 chocolate chips apiece. What is the probability of getting a co

sp2606 [1]

Answer:

0.7262

Step-by-step explanation:

Let random variable = X

Probability of getting a cookie with at least 55 chips:

P(55≤ X ≤78), where X1 = 55 and X2 = 78

Let mean, U = 66 and standard deviation, S.D. = 10

Let Z = X - U/S.D; Z1 = X1 - U/S.D and Z2 = X2 - U/S.D

Z1 = 55 - 66/10 = - 1.1

Z2 = 78 - 66/10 = 1.2

P(X1≤ X ≤ X2) = P(X1 -U/S.D ≤ X - U/S.D ≤ X2 - U/S.D)

P(Z1 ≤ Z ≤ Z2) = P(0 ≤ Z ≤ Z1) + P(0 ≤ Z ≤ Z2)

Hence, (55 ≤ X ≤ 78) = P( - 1.1 ≤ Z ≤ 1.2)

∴ P(-1.1 ≤ Z ≤ 1.2) = P(0 ≤ Z ≤ 1.1) + (0 ≤ Z ≤ 1.2)

= 0.3413 + 0.3849 = 0.7262

-37= n/23 what is n?

Vlada [557]

-37 = n
 23

to solve for n, undo what is happening to the n. if the n is being divided by 23 to get -37, then multiply both sides by 23 to figure out what n is.

-37 * 23 = n * 23
 23

-851 = n
