Answer:

We fail to reject H0

Step-by-step explanation:

Null hypothesis : H0 : Plocal ≤ Pnational

Alternative hypothesis : H1 : Plocal > Pnational

Plocal = P1 = 65/100 = 0.65

Pnational = P2 = 61/100 = 0.61

n1 = 100 ; n2 = 100

Mean, m = P1 - P2 = 0.65 - 0.61 = 0.04

The standard deviation : = sqrt(Variance)

Variance = P1(1 - P1) /n1 + P2(1 - P2) /n2

Variance = 0.65(0.35)/100 + 0.61(0.39)/100

Variance = 0.002275 + 0.002379 = 0.004654

Standard deviation (s) = √(0.004654) = 0.06822

Z = m/s = 0.04 / 0.06822 = 0.586

Using the p-value from Z score calculator :

Hence, Pvalue for a Zscore 0.586 at 5% = 0.278938

Since ;

P-value is > α ; 0.278938 > 0.05

Then we fail to reject H0

Answer:

A=18.1, B=72.4, and C=89.5

Step-by-step explanation:

Where A, B and C represent their respective angles:

We are given that:

B=4A

C=5A−1

And since ABC make up a triangle, we know that:

A+B+C=180

Since we have three variables and three equations, we can solve for A, B, and C. To solve for A:

Take the equations B=4A and C=5A−1, and plug B and C into the last equation:

A+B+C=180

A+4A+5A−1=180

10A – 1 + 1 = 180 + 1

10A=181

10 /10 x A = 181/10

             A = 18.1

Then we can plug this value into the first two equations to solve for B and C:

B=4A

B=4(18.1)=72.4

C=5A−1

C=5(18.1)−1= 90.5 - 1=89.5

So A=18.1, B=72.4, and C=89.5

Hope this helps!

The size of ∠A is 18.1°.

The size of ∠B is  72.4°.

The size of ∠C is 89.5°.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Triangle ABC

∠A = x

∠B = 4x

∠C = 5x - 1

Now,

The sum of all the angles in a triangle is 180.

This means,

x + 4x + 5x - 1 = 180

10x - 1 = 180

10x = 181

x = 18.1

Now,

∠A = 18.1°

∠B = 4 x 18.1 = 72.4°

∠C = 5 x 18.1 - 1 = 89.5°

Thus,

The sizes of the angles are:

18.1°, 72.4°, and 89.5°

Step-by-step explanation:

-(49100-1021)

-48079

Answer:

The answer is A^2

Step-by-step explanation:

When you are dividing, You subtract exponents if they have the same base.

The base (variables) are the same. So you subtract the powers.

Which are 5 and -3. You subtract those two powers 5 minus negative -3 which gives you 2.  So it's  a^-2

Sorry for the long explanation I hope you understand it. And if I made it harder to understand the answer sorry oops have a good day and stay safe ;D.

Answer:

0.25

Step-by-step explanation:

Bag 1 :

Number of marbles = 6

Number of Blue marbles = 3

Bag 2:

Number of marbles = 4

Number of Blue marbles = 2

Recall :

Probability = required outcome / Total possible outcomes

For Bag 1:

P(blue) = Number of Blue marbles / total marbles

P(blue) = 3 / 6 = 1/ 2

For Bag 2:

P(blue) = Number of Blue marbles / total marbles

P(blue) = 2 / 4 = 1/ 2

Probability of a picking a blue marble from each bag :

1/2 * 1/2 = 1/4 = 0.25

Answer:

C

Step-by-step explanation:

By tracing the figure, we see that we go around a semicricle twice and go in a straight path twice. So the perimeter of this figure consists of two semicircles and two line segments, hence the answer is C.

Priya is standing 528.63 feet away from the base of Gateway Arch in St. Missouri.

In the field of mathematics known as trigonometry, correlations between angles and length ratios are studied. The field was created in the Hellenistic era in the third century BC as a result of the use of geometry in astronomical research.

Given parameters:

Height of the Gateway Arch in St. Missouri = 630 feet.

Priya have to look up at a 50° angle to see the top of the arch.

Now from definition of tanθ in trigonometry:

tan50° = height of the Gateway Arch in St. Missouri ÷ distance of Gateway Arch in St. Missouri

hence, distance of Gateway Arch in St. Missouri = height of Gateway Arch in St. Missouri ÷  tan50°

= 630 feet  ÷  tan50°

= 528.63 feet.

Hence, she is standing 528.63 feet away from the base of Gateway Arch in St. Missouri.

b) 24.30 dollars

c) - 5 dollars

Step-by-step explanation:

b) 27 / 10%

Divide 27 by 10/100 by multiplying 27 by the reciprocal of 10/100.

27 x 100/10

Multiply 27 and 100 to get 2700.

2700/10

Divide 2700 by 10 to get 270.

270

Divide 270 by 100 to get 2.7

Subtract 27.00 - 2.7 = 24.30

Answer:

Follows are the solution to the given question:

Step-by-step explanation:

They can count the days of the year 1 to 365. The random project consists of drawing a sample of n objects from D where elements are n people's birth in a group but instead, D = {1,....365}. And then there's the issue.

[tex]S=365^n[/tex]

This because the list of future birthdays of n people was its test point; therefore m points will be in the sequence so each point contains 365 distinct outcomes. The probability function P for \Omega is that any event is likely to happen in 365 days.

[tex]P(x)=\frac{1}{365^{n}}[/tex]

if x is between 1 and 365 as well as the occurrence is just all similarly possible

In point i:

That somebody mentions their birthday throughout the party

Guess I was born on day b. Therefore the consequence of "x is in A" is "b is now in the series of x," which is to say, b = bk for some amount k approximately 1 and n.

In point ii:

Any 2 persons share the same birthday at this party". A result x is in B" means which "two of entries in x are same." This means that perhaps the outcome x is in B if or only if bj = bk is in B of two numbers j, and k of 1, of two. , no, n.

In point iii:

Many three students share the same birthday with both the party. The consequence is x at the level of C only when bj = bk = bl at three (different) indices, j, k, l, 1. , no, n.
