Answer:

single sample z test

Step-by-step explanation: The correct statistics test is the single sample A test.

A one-sample z-test is used to test whether a population parameter is remarkably different from some hypothesized value. Each makes a statement about how the true population mean μ is related to some hypothesized value M. It is used to test whether the mean of a population is greater than, less than, or not equal to a specific value.

Plz help me, thank you

Answer:

$P=40(1.03526)^{t}$

Step-by-step explanation:

<u>Exponential Growth </u>

The natural growth of some magnitudes can be modeled by the equation:

$P=P_o(1+r)^{t}$

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

The initial number of bacteria is Po=40 and it doubles (P=2Po) at t=20 min. With that point we can find the value of r:

$2P_o=P_o(1+r)^{20}$

Simplifying:

$(1+r)^{20}=2$

Solving for 1+r:

$1+r=\sqrt[20]{2}$

$1+r=1.03526$

The exponential function that models the situation is:

$\mathbf{P=40(1.03526)^{t}}$

Solve the equations 11(x+10)=132

VladimirAG [237]

11(x+10) = 132

Distributive property

11x + 110 = 132

Now isolate the variable.

11x + 110 = 132
-110 -110

132 - 110 = 22

11x = 22

11x/11 = 22/11
x= 2

Answer: x = 2

sineoko [7]

Answer:

A factor is a number that when its multiplied with another number, gives a product of a given number. Example: The factors of 21 are 7,3,1 and 21. A multiple is a number that can be divided by another number a certain amount of times evenly (without a remainder). Example: Some multiples of 4 are: 8, 12, 16, and 20.

Please help me ASAP!

Snezhnost [94]

Answer:

y = 6.5

Step-by-step explanation:

When triangles are similar, we can set up a proportion to compare the sides. I will have the "left" side on the bottom of the fractions, and the side I am solving for on the top.

$\frac{y}{6} =\frac{13}{12}$

[Cross multiply]

12y = 78

y = 6.5
