The answer is most likely C. A relation that is a function because that is a function graph below. So the answer is C.

Answer:

This graph is considered a quadratic function however the graph passes the y axis twice meaning that it contains 2 values therefore the answer is A relation that is NOT a function.

Hope this helps :)

Monica [59]

Answer:

I believe that the answer is

Galina was correct when she said: there are 2 possible outcomes.

Elroy was correct when he said: multiply the 10 outcomes

Step-by-step explanation:

I looked this up and found that when you flip a coin 10 times you get 2^10 = 1024 but including other possibilities there are only 1000 combinations. Meaning that there are 2 possible outcomes for every coin flip and in order to find those combinations you have to multiply 2 to itself for however many times you were to flip a coin.

For Example: Flip a coin 3 times there are 2 possibilities for every time you flip it. So the answer would be 2*2*2=8 combinations.

I hope this helps. :)

Write an i explicit formula for an, the nth term of the sequence 200, 40, 8, ....

Ugo [173]

Answer:

$T_n = 200 * (\frac{1}{5})^{n-1$

Step-by-step explanation:

Given

$Sequence: 200,40,8$

Required

The nth term

The given sequence is a geometric sequence.

So, first we identify the first term

$a = 200$

Calculate common ration

$r = \frac{40}{200}$ or $r = \frac{8}{40}$

$r = \frac{1}{5}$

So, the nth term is:

$T_n = ar^{n-1$

$T_n = 200 * (\frac{1}{5})^{n-1$

Radioactive fallout from testing atomic bombs drifted across a region. There were 220 people in the region at the time and 36 of

vazorg [7]

Answer:

(a) Yes, the death rate observed in the group unusually high.

(b) Yes, this prove that exposure to radiation increases the risk of cancer.

Step-by-step explanation:

In a region where radioactive fallout from testing atomic bombs drifted across, 36 of the 220 people died of cancer.

The sample proportion of the number of people dying of cancer in this region is:

$\hat p =\frac{36}{220} =0.164$

It is estimated by the cancer expert that there will be 33 cancer deaths in a group of this size.

The population proportion is: $p=\frac{33}{220} =0.15$

A hypothesis test for single proportion can be performed to test if the proportion of cancer deaths was high or not and whether it was due to the increase in radiation.

The hypothesis can be defined as:

H₀: The proportion of death due to cancer in this region is 0.15, i.e. p = 0.15.

Hₐ: The proportion of death due to cancer in this region is more than 0.15, i.e. p > 0.15.

Assuming the population is Normally distributed since the sample size is large.

Assume the level of significance is α = 0.05.

The test statistic is:

$z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}\\= \frac{0.164-0.15}{\sqrt{\frac{0.15(1-0.15)}{220}}} \\=0.581$

The test statistic value is 0.581.

Decision rule:

If the p-value of the test is less than the significance level then the null hypothesis is rejected and vice versa.

The p-value of the test is:

$P(Z>0.581)=1-P(Z$

**Use a z-table for the p-value.

The p-value = 0.281 > α = 0.05.

The null hypothesis was failed to be rejected.

(a)

As the null hypothesis was not rejected at 5% level of significance it can be concluded that the death rate due to cancer observed in this group of people is unusually high.

Yes, the death rate observed in the group unusually high.

(b)

It was previously mentioned that a radioactive fallout from testing atomic bombs drifted across this region. Due to this 36 people died of cancer in this region.

As the death rate observed in the group unusually high, it can be said that the increase in the death rate due to cancer was due to the excessive exposure to radiation.

Yes, this prove that exposure to radiation increases the risk of cancer.

Help please math answer ASAP NO LINKS

Sidana [21]

5/11 is a fraction, so it is for sure a rational number and a real number.

Since it is a fraction, it is NOT irrational (which means "not rational" or "not a fraction).

It is NOT an integer, whole number, or natural number, becuase it is only a piece of a whole. 5/11 ≈ 0.454545..., and intergers, whole numbers, and natural numbers don't involve decimals.
