Answer:

y=-3

Step-by-step explanation:

-2(-25)+2y=44

Substitute -25 for x

Then multiply

50+2y=44

-50        -50

Subtract 50 on both sides

2y/2=-6/2

Divide 2 and 6

Answer is -3

A searchlight rotates through one complete revolution every 52 seconds how long does it take to rotate 90 degrees?
nasty-shy [4]

Time taken to rotate 90° is 13 seconds

<u>Explanation:</u>

Given:

To complete one revolution, the searchlight takes 52 seconds

One revolution = 360°

So,

360° is completed in 52 seconds

Time taken to complete 90° is \frac{52}{360} X 90

                                            = 13 sec

Therefore, time taken to rotate 90° is 13 seconds

2. Positive Correlation

This is achieved when the slope (value) of both x and y increase

3. Strong Correlation

This is often achieved when there's uniformity in slope x and y.

4. Weak Correlation

This is achieved when there's no uniforms in slope x and y

5. Linear

Linearity refers to whether a data pattern is linear (straight)

6. Nonlinear

Non-Linearity refers to whether a data pattern is curved.

Step-by-step explanation:

Hayden rode his bike 5 times. Each time, he biked a 3-mile path, a 2-mile path, and a 2 1/4 -mile path.

The expression represents the total number of miles he biked is calculated as:

The number of times he rode his bike × (sum of the number of miles he biked)

= 5 × ( 3 mile + 2 miles + 2 1/4 miles)

= 5 × (3 + 2 + 2 1/4)

Therefore, Option A is the correct option
