Answer:

f(0) = 243 . . . cats at the start

Step-by-step explanation:

The exponential function tells you the number of cats after t years is ...

f(t) = 243(1/3)^t

When t=0, the exponential factor is 1, so the value of the function is the multiplying constant.

f(0) = 243

This means there were 243 stray cats in town when the animal control program started.

Last year, 50% of MNM. Inc. employees were female. It is believed that there has been a reduction in the percentage of females i

Serhud [2]

Answer:

We conclude that there has been a significant reduction in the proportion of females.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 400

p = 50% = 0.5

Alpha, α = 0.05

Number of women, x = 118

First, we design the null and the alternate hypothesis

$H_{0}: p = 0.50\\H_A: p < 0.50$

This is a one-tailed test.

Formula:

$\hat{p} = \dfrac{x}{n} = \dfrac{118}{400} = 0.45$

$z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Putting the values, we get,

$z = \displaystyle\frac{0.45-0.50}{\sqrt{\frac{0.50(1-0.50)}{400}}} = -2$

Now, we calculate the critical value.

Now, $z_{critical} \text{ at 0.05 level of significance } = -1.645$

Since the calculated z-statistic is less than the critical value, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.

Thus, there has been a significant reduction in the proportion of females.

Sphinxa [80]

There are 8 ounces per cup, meaning that you would have to multiply to find your answer.
Multiply 36X8.
36X8=288

What is 18.4 times 3.40 and the wprk showed

dusya [7]

Decimal division is super easy, let me show you how.

First, let's remove the decimal from both numbers. We have 184 and 340. Now let's multiply those two numbers.

184*340 = 62560.

Now, we need to figure out how many decimal places are in the original decimals. 18.4 has one decimal place, and 3.4 has one decimal place. (We don't count zeros at the end of a decimal as a decimal place.)

Now that we've figured out that there was a total of two decimal places, there can only be two decimal places in the answer. Let's take the 62560 that we got, and put a decimal in it. Remember, only two decimal places.

If there's only two decimal places in 62560, it would look like this: 62.56 (Remember, zeros at the end of a decimal does not count as a decimal place!)

There's your final answer. 62.56.

Hope this explanation helped you out. :)

It is known triangles abc is congruent to def . If AB=5 and BC=10, AC=8 and DF=2x-6 solve for x.

Pepsi [2]

So df = 8 so then 2x-6=8 which means that x is 7
