Stacie did the mistake that he put the value of base in place of perpendicular and vice versa.

<h3>What is triangle?</h3>

The triangle is geometric shape which includes 3 sides and sum of interior angle should not grater than 180°

Solution is supposed to be


tan_ (-1) (28/21) = 53.33

Thus,Stacie did the mistake that he put the value of base in place of perpendicular and vice versa.

Answer:

To be able to approximate the sampling distribution with a normal model, it is needed that np \geq 10 and n(1-p) \geq 10, and both conditions are satisfied in this problem.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they will make payments on time, or they won't. The probability of a person making the payment on time is independent of any other person, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The sampling distribution can be approximated to a normal model if:

np \geq 10 and n(1-p) \geq 10

Based on past experience, a bank believes that 8.9 % of the people who receive loans will not make payments on time.

This means that p = 0.089

The bank has recently approved 220 loans.

This means that n = 220

What must be true to be able to approximate the sampling distribution with a normal model?

np = 220*0.089 = 19.58 \geq 10

n(1-p) = 220*0.911 = 200.42 \geq 10

To be able to approximate the sampling distribution with a normal model, it is needed that np \geq 10 and n(1-p) \geq 10, and both conditions are satisfied in this problem.

A recipe says it produced the best sweet tea. In addition to using tea bags, the recipe calls for ½ cup of sugar for every 1 ½ c
Sergio [31]

Answer:

The relationship between the number of cups of water and sugar  in the recipe is w = ¹/₃(s)

Step-by-step explanation:

Given;

number of cups of sugar = s

number of cups of water = w

The relationship between the number of cups of water and sugar in this recipe is given as;

½ cup of sugar is proportional to 1 ½ cups of water

\frac{1}{2} s = \frac{3}{2}w\\\\s= 3w\\\\w = \frac{s}{3}

Therefore, the relationship between the number of cups of water and sugar  in the recipe is w = ¹/₃(s)

Can someone help me pleaseee
Bumek [7]

Answer:

x ≈ 26.4

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos47° = \frac{adjacent}{hypotenuse} = \frac{CD}{AD} = \frac{18}{x} ( multiply both sides by x )

x × cos47° = 18 ( divide both sides by cos47° )

x = \frac{18}{cos47} ≈ 26.4 ( to the nearest tenth )
