Answer: 7/5

This is how we add

4/5+3/5

Step 1

Since our denominators match, we can add the numerators.

4 + 3 = 7

That gives us an answer of

7/5

Step 2

Can this fraction be reduced?

First, we attempt to divide it by 2...

No good. So next you try the next prime number, which is 3...

No good. So next you try the next prime number, which is 5...

No good. So next you try the next prime number, which is 7...

No good. 7 is larger than 5. So we're done reducing.

And we're done! Here's the final answer to 4/5 + 3/5

4/5 divided by 3/5 equals 7/5

Using the binomial distribution, it is found that there is a 0.056 = 5.6% probability that more than 7 will make a purchase.

<h3>What is the binomial distribution formula?</h3>

The formula is:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem:

There are 12 customers, hence n = 12.

The probability of any of them making a purchase is of p = 0.4.

The probability that more than 7 will make a purchase is given by:

P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12).

Hence:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 8) = C_{12,8}.(0.4)^{8}.(0.6)^{4} = 0.042$

$P(X = 9) = C_{12,9}.(0.4)^{9}.(0.6)^{3} = 0.012$

$P(X = 10) = C_{12,10}.(0.4)^{10}.(0.6)^{2} = 0.02$

$P(X = 11) = C_{12,11}.(0.4)^{11}.(0.6)^{1} \approx 0$

$P(X = 12) = C_{12,12}.(0.4)^{12}.(0.6)^{0} \approx 0$

Then:

P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) = 0.042 + 0.012 + 0.02 + 0 + 0 = 0.056.

0.056 = 5.6% probability that more than 7 will make a purchase.

A right triangle has side lengths 5, 12, and 13 as shown below. Use these lengths to find tan B, sinB, and cos B. (marking brain

Naddika [18.5K]

Answer:

tan B = 12 /5

sin B = 12/13

cos B = 5/13

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan B = opp/ adj = 12 /5

sin B = opp/hyp = 12/13

cos B = adj/hyp = 5/13

NEED ANSWERED ASAPPPP!!!!

Juli2301 [7.4K]

Option A:

m∠B = 28°

Solution:

Given ABC is a triangle on the circle.

m∠A = 62°

<em>The angle subtended by a diameter or a semicircle on any point of circle is 90°.</em>

AB is a diameter and C is the angle subtended on a diameter.

Therefore, m∠C = 90°.

Triangle sum property:

<em>Sum of the angles of the triangle = 180°</em>

m∠A + m∠B + m∠C = 180°

62° + m∠B + 90° = 180°

m∠B + 152° = 180°

m∠B = 180° – 152°

m∠B = 28°

The measure of angle B is 28°.

Hence Option A is the correct answer.
