Answer:

692914.56

Step-by-step explanation:

(9.2 x 102)

= 938.4

(7.1 x 104)

= 738.4

938.4 x 738.4

=

I need help for this question please!!!!

Arisa [49]

Answer:

a. 35 degrees

b. 145 degrees

Step-by-step explanation:

a. Since the two base angles of this triangle are congruent, we can conclude that the triangle is <em>isosceles, </em>which means that the two base angles and sides are congruent.

Now, knowing that information, we can subtract 110 from 180 (the sum of all interior angles in a triangle) and we get 70. But this isn't our answer. This is the sum of both base angles. Since the base angles are congruent, we can divide the 70 by 2 to get the measure of ONE base angle, which is 35 degrees.

b. There are two approaches to solve this problem. I have worked both out.

1) We can use the Exterior Angle Theorem, which states that the sum of the interior angles is equal to the exterior angle. We can add 110 to 35, so we get 145 degrees as the measure of <1.

2) The second approach is supplementary angles. Since we see that one of the base angles and <1 is on the same line, we can subtract 35 from 180 to find the measure of <1 to get 145 degrees.

Either way you use, you get the correct answer. Hope this helped!

Is 2/5 a natural number

s344n2d4d5 [400]

Natural numbers are counting numbers. Natural numbers cannot be a fraction with a different numerator and denominator when simplified. Therefore 2/5 is not a natural number.

Which is a better buy? 3 for $1.00 or 10 for $3.00

zvonat [6]

10 for $3.00. Even though it costs a little more Maybe the extra will come in handy like lets say if lets say we are buying a 10 pack of pencils for $3.00 What if we give some away or we sell them. And It might be a better brand too, The $1.00 pack could be from the dollar tree and could break in like a day. But the $3.00 version could be much stronger and better. UwU Hope I helped

The mayor of a town has proposed a plan for the annexation of a new community. A political study took a sample of 800 voters in

irakobra [83]

Answer:

Step-by-step explanation:

Hello!

A survey was conducted to know the population's opinion about the mayor's proposed plan of the annexation of a new community.

Of a sample of 800 voters, 50% favored the annexation.

The political strategist thinks that less than 55% of the voters favor the annexation.

For me, the first step of every statistical exercise is to determine the study variable and its distribution.

X: Number of voters, out of 800, in favor of annexation.

This variable has a binomial distribution with parameters n and p.

The parameter of the study is the population proportion of voters that favor the annexation.

The statistical hypotheses are:

H₀: p ≥ 0.55

H₁: p < 0.55

α: 0.02

To test the population proportion the best statistic to use is the approximation to standard normal:

$Z= \frac{p'-p}{\sqrt{\frac{p(1-p)}{n} } }$ ≈N(0;1)

$Z_{H_0}= \frac{0.5-0.55}{\sqrt{\frac{0.55*0.45}{800} } } = -2.84$

This hypothesis test is one-tailed to the left, this means, that you will reject the null hypothesis to small values of the statistic Z.

The critical value is $Z_{\alpha } = Z_{0.02} = -2.054$

The p-value is one-tailed in the same direction as the test and you can calculate it as:

P(Z≤-2.84)= 0.002

The p-value: 0.002 is less than the significance level α: 0.02 ⇒ The decision is to reject the null hypothesis.

Using a significance level of 2% the decision is to reject the null hypothesis. Then you can conclude that the claim of the political strategist is correct and the population proportion of voters that favor the annexation is less than 55%.

I hope it helps!
