How Can Help Me(a+b)^24ab
Answer 2

Answer:

(a+b) ²≥4ab explanation below↓↓↓↓

Step-by-step explanation:

We know that

(a-b) ²≥0

a²-2ab+b²≥0

Move -2ab to the other side

a²+b²≥2ab

Add 2ab to both sides

a²+2ab+b²≥4ab

(a+b) ²=a²+2ab+b² therefore :

(a+b) ²≥4ab

Mary bought 10 1/2 pounds of turkey for a picnic. There were 4 3/4 pounds of turkey left after making 25 turkey sandwiches. Which statement is true?

A The quotient −534÷25=−23100 means the average change in the total amount of turkey decreased by 23100 pound per sandwich.

B The quotient −534÷25=−23100 means the average change in the total amount of turkey increased by 23100 pound per sandwich.

C The quotient 534÷25=23100 means the average change in the total amount of turkey decreased by 23100 pound per sandwich.

D The quotient 534÷25=23100 means the average change in the total amount of turkey increased by 23100 pound per sandwich.

Answers

Answer:

HEYO!! soo the answer is A!! I tried B like the other person said but i got it wrong! so its A!

Step-by-step explanation:

Option A is correct. The quotient −534÷25=−23100 means the average change in the total amount of turkey decreased by 23100 pound per sandwich.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given that Mary bought [tex]10\frac{1}{2}[/tex] pounds of turkey for a picnic.

There were [tex]4\frac{3}{4}[/tex] pounds of turkey left after making 25 turkey sandwiches.

We need to find which statement will be true from the given options.

The solution we get by using the division process.

Division is nothing but splitting something to equal parts.

The quotient −534÷25=−23100 means the average change in the total amount of turkey decreased by 23100 pound per sandwich is the true statement.

Hence, Option A is correct. The quotient −534÷25=−23100 means the average change in the total amount of turkey decreased by 23100 pound per sandwich.

Car repairs: Let be the event that a new car requires engine work under warranty and let be the event that the car requires transmission work under warranty. Suppose that ,P(E) = 0.10 , P(T) = 0.02 and P(E,T) = 0.01 .
(a) Find the probability that the car needs work on either the engine, the transmission, or both.
(b) Find the probability that the car needs no work on the engine.

Answers

Answer:

a) 0.11 =  11% probability that the car needs work on either the engine, the transmission, or both.

b) 0.9 = 90% probability that the car needs no work on the engine.

Step-by-step explanation:

P(E) = 0.10 , P(T) = 0.02 and P(E,T) = 0.01 .

This means that:

Only engine: 0.1 - 0.01 = 0.09

Only transmission: 0.02 - 0.01 = 0.01

Both engine and transmission: 0.01

(a) Find the probability that the car needs work on either the engine, the transmission, or both.

0.09 + 0.01 + 0.01 = 0.11

0.11 =  11% probability that the car needs work on either the engine, the transmission, or both.

(b) Find the probability that the car needs no work on the engine.

Probability of needing work on engine:

0.09 + 0.01 = 0.1

Not needing:

1 - 0.1 = 0.9

0.9 = 90% probability that the car needs no work on the engine.

The length of the base of a right triangle with an area of 24 square meters and a height of 4 meters is 12 meters.

The correct option is C.

What is a right-angled triangle?

A triangle is said to be right-angled if one of its inner angles is 90 degrees, or if any one of its angles is a right angle.

Given:

An area of the right triangle = 24 square meters.

Height = 4 meters.

Then,

An area of the right triangle = 24 square meters.

1/2 x base x height = 24

1/2 x base x 4 = 24

Base = 12 meters.

Therefore, the base is 12 meters.
