RoseWind [281]2 years ago
3 0

Answer:

Area: 2206.86 square m

Perimeter: 194.25 m

Step-by-step explanation:

Area:

30 x 50 = 1500 square m

30/2 = 15 = the radius of the semi circles

pi x 15^2 = 706.86 square m

1500 + 706.86 = 2206.86 square m

Perimeter:

pi x 15 x 2 = 94.25 m

94.25 (perimeter of both semi circles) + (50 x 2) = 194.25 m

Mina tosses two number cubes labeled 1 to 6. What is the probability that the sum is equal to five?
coldgirl [10]

(1,4)

(4,1)

(2,3)

(3,2)

so there are 4 different combinations that equal 5

 6 x 6 = 36 total possible outcomes of the dice

so they have a 4/36 reduces to 1/9 probability of equaling 5

Test the claim that the proportion of people who own cats is larger than 40% at the 0.025 significance level. The null and alter
Alecsey [184]

Answer:

H 0 : p ≤ 0.4 H a : p > 0.4

And based on the alternative hypothesis we can conclude that we have a right tailed test

Step-by-step explanation:

Data given

n=300 represent the random sample size

\hat p=0.45 estimated proportion of people with cats

p_o=0.40 is the value that we want to test

\alpha=0.025 represent the significance level

z would represent the statistic

p_v represent the p value

Null and alternative hypothesis

We want to test if the true proportion of people with cats is higher than 0.4, so then the best alternative is:  

Null hypothesis:p\leq 0.4  

Alternative hypothesis:p > 0.4  

H 0 : p ≤ 0.4 H a : p > 0.4

And based on the alternative hypothesis we can conclude that we have a right tailed test

The statistic is given by:  

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

Replacing we got:

z=\frac{0.45 -0.4}{\sqrt{\frac{0.4(1-0.4)}{300}}}=1.768
