Answer:

12 in^2

Step-by-step explanation:

The figure with the given area is twice as big as the small figure and these are similar figures. Therefore we divide 24/2 = 12

14.62 rounded to the nearest number

ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

To answer this, we would have to look at the last place first, which is the hundredths place. In the hundredths place, we have a 2. 2 is less than 5, so we would just pretend it isn't there since we would round down. Now, looking at the tenths place, which is the 6, we can determine whether or not we round. If the number is 5 and above, (including 5) we would round up. In this case, it is 6, so we would round the number in front of it (4) up by one to get 15.

(1-cos0)(1+cos0) pls help

topjm [15]

Answer:

sin²Ф

Step-by-step explanation:

I doubt that you actually meant "cos 0" ... that has a value of 1.

If you meant (1-cos Ф)(1+cos Ф), then this product is 1 - cos²Ф.

That, in turn, is equal to sin²Ф

A manufacturer claims that fewer than 6% of its fax machines are defective. to test this claim, he selects a random sample of 97

AfilCa [17]

Let P be the population proportion, p be the sample proportion, n be the sample size.

A manufacturer claims that fewer than 6% of its fax machines are defective. It means P=0.06

Sample size n=97 and sample proportion p=0.05

The hypothesis to be tested is

H0: P ≥ 0.06 V/s Ha: P < 0.06

Here the hypothesis for testing population proportion we use z test statistics. Z test statistics is give by

Z = $\frac{p -p_{0}}{\sqrt{p_{0}(1-p_{0})/n}}$

Where p =sample proportion = 0.05

p0 = hypothesized proportion value =0.06

Using given values into test statistics we get

Z = $\frac{0.05 -0.06}{\sqrt{0.06(1-0.06)/97}}$

Z = -0.41

The p-value for left tailed alternative hypothesis is given by

P-value = P(z < z cal)

where zcal = Z test statistics value

Here zcal = -0.41

P-value = P(Z < -0.41)

Using z score table to find probability below z=-0.41

P-value = 0.3409

P-value for testing the given claim is 0.3409
