Answer:

the answer should be 3146 because you have 11 cm for both length and width and you have also 11cm height but there is also 15 cm height for the triangle so if you times all of them together it should give you 3146

What is the value of p?

user100 [1]

Answer:

Step-by-step explanation:

The angle adjacent to 133 and 133 form a straight angle and are supplementary, hence

adjacent angle = 180° - 133° = 47°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles. The angle 90 is an exterior angle, thus

p + 47 = 90 ( subtract 47 from both sides )

p = 43° → A

A line with a slope of 3 passes through (2,5). Which choice is an equation of this line?

damaskus [11]

The point-slope form of the equation of a line of slope m through point (h, k) is given by

... y - k = m(x - h)

Substituting your given values, you have ...

... B. y - 5 = 3(x - 2)

kotykmax [81]

Answer:

We conclude that majority of the citizens does not feel the country could develop a way to protect itself from atomic bombs.

Step-by-step explanation:

We are given that an organization asked 1403 randomly sampled American citizens, "Do you think we can develop a way to protect ourselves from atomic bombs in case others tried to use them against us?" with 737 responding yes.

We have to conduct a test to determine that a majority of the citizens feel the country could develop a way to protect itself from atomic bombs in 1945.

Let p = percentage of citizens feel the country could develop a way to protect itself from atomic bombs in 1945.

SO, Null Hypothesis, $H_0$ : p $\leq$ 50% {means that majority of the citizens does not feel the country could develop a way to protect itself from atomic bombs}

Alternate Hypothesis, $H_A$ : p > 50% {means that majority of the citizens feel the country could develop a way to protect itself from atomic bombs}

The test statistics that will be used here is One-sample z proportion statistics;

T.S. = $\frac{\hat p-p}{{\sqrt{\frac{\hat p(1-\hat p)}{n} } } } }$ ~ N(0,1)

where, $\hat p$ = proportion of citizens responding yes in a sample of 1403 citizens = $\frac{737}{1403}$

n = sample of citizens = 1403

So, test statistics = $\frac{\frac{737}{1403} -0.50}{{\sqrt{\frac{\frac{737}{1403}(1-\frac{737}{1403})}{1403} } } } }$

= 1.898

The value of the test statistics is 1.898.

Now at 1% significance level, the z table gives critical value of 2.3263 for right-tailed test. Since our test statistics is less than the critical value of z as 1.898 < 2.3263, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which we fail to reject our null hypothesis.

Therefore, we conclude that majority of the citizens does not feel the country could develop a way to protect itself from atomic bombs.
