Leah flips a coin, and then she spins a spinner with 3 equal sections colored red, green, and blue. What is the probability that

svet-max [94.6K]

Answer: 33.3%

Step-by-step explanation:

Since there are two sides to a coin, the probability is 1/2. Since there are 3 sections on the spinner, the probability would be 2/3. Since "and" means multiply in this scenario, your answer would be 2/6, which simplifies to 1/3, which, in percentage form to the nearest percent, is 33.3%.

Most adults would not erase all of their personal information online if they could. A software firm survey of 480 randomly selec

Westkost [7]

Answer:

-7.90

Step-by-step explanation:

Let's write the null hypothesis (H0) and alternative hypothesis (Ha) from the claim statement

P = population proportion of adults who would erase all of their personal information online if they could

H_{0}:P=0.5

H1 P< 0.5

Let's write the given information:

n = sample size = 480

sample proportion = $\hat p = 0.35$

formula of z test statistic for one sample proportion test is as follows:

$Z=\frac{\hat p-P}{\sqrt{\frac{P\times(1-P)}{n}}}$

plug the above values in the above formula we get

$Z =\frac{0.35-0.5}{\sqrt{\frac{0.35(1-0.5)}{480}}}=Z=-7.85584$

So that the test statistic value is -7.90 (Rounded up to two decimal places)

First replace x and y by 3 and 4.

(3*(x)+1)/(4*(y)^2)

((3*(3))+1)/(4*((4)^2)) = (9+1)/(4*16) = 10/64 = 5/32.

5/32 is your answer.
