Answer-

A. More churches lead to more crimes

Solution-

Properties of Correlation Coefficient

1- A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.

2- A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.

Here,there is a positive correlation between the number of churches and the city’s crime rate. So as the number of churches increase, the crime rate also gets increased.

How much sugar syrup would you get by Making 5% sugar syrup using 6g sugar?

kherson [118]

Answer: 120 grams.

Step-by-step explanation:

Let x be the amount of sugar syrup made by 5% sugar syrup using 6g sugar.

Also, 5% =0.05

Therefore, 5% sugar syrup =5% of x = 0.05x

According to the question, we have

$0.05x=6\\\text{Divide 0.05 on the both sides we get}\\\Rightarrow\ x=\frac{6}{0.05}\\\Rightarrow\ x=\frac{600}{5}\\\Rightarrow\ x=120$

Hence, 120 grams sugar syrup is made by 5% sugar syrup of 6g sugar.

Use the 3 trig ratios to find each unknown side length. Round all answers to 1 decimal

STatiana [176]

Note: You missed to add some of the details of the question.

Hence, I am solving your concept based on an assumed graph which I have attached. It would anyways clear your concept.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the right angled-triangle ABC as shown in the attached diagram

From the triangle:

Ф= ∠C = 30°

AB = 6 units

BC = y

tan Ф = opp ÷ adjacent

The opposite of ∠C = 30° is the length '6'.

The adjacent of ∠C = 30° is the length 'y'.

As Ф= ∠C = 30°

tan Ф = opp ÷ adjacent

tan 30 = 5 ÷ y

1 ÷ √3 = 5 ÷ y

y = 8.7 units

Therefore, the length of the unknown side length 'y' is 8.7 units.

Which algebraic expression is a polynomial with a degree of 5

anygoal [31]

Answer: For example, the polynomial which can also be expressed as has three terms. The first term has a degree of 5 (the sum of the powers 2 and 3), the second term has a degree of 1, and the last term has a degree of 0. Therefore, the polynomial has a degree of 5, which is the highest degree of any term.
