Reptile [31]

Answer: Our required probability is 0.3162.

Step-by-step explanation:

Since we have given that

n = 60

Probability of success = $\dfrac{2}{3}$

Probability that at most 39 of these relays come from supplier A would be

$P(X\leq 39)=binomcdf(60,\dfrac{2}{3},39)=0.3162$

Hence, our required probability is 0.3162.

Answer:

8 and 5/8

Step-by-step explanation:

The question is just subtraction of fractions. First, you subtract the whole numbers. 10-2=8. Then you subtract the fractions. To do this, you have to make them equivalent. Just multiply the 1/4 by 2 and you get 2/8. Now, 7/8 - 2/8 = 5/8. Your final answer is 8 and 5/8

Angles ABC and DBE are vertical angles, with angle ABC = 4x, and angle DBE =( 2x+18)

Dmitrij [34]

V<span>ertical angles are equal.
We have 4x = 2x + 18.
Then, 2x = 18;
x = 18 </span>÷ 2;
x = 9 degrees;
The measure of angle DBE is 2 × 9 + 18 = 36 degrees.

Evaluate each expression for the given value of the variable.<br> x + 2x - x - 1; x = 2

MaRussiya [10]

x + 2x - x - 1

Substitute 2 for x into the expression.

(2) + 2(2) - (2) - 1

Multiply 2 * 2 first.

(2) + (4) - (2) - 1

Solve from left to right.
(2 + 4) - 2 - 1 = 6 - 2 - 1

6 - 2 - 1

Solve from left to right.
(6 - 2) - 1 = 4 - 1

4 - 1 = 3

<h3>Your answer is 3.</h3>

What is the answer Timothy curtain company is making curtains for a local hotel he wants each certain to be 48 inches long at th

Travka [436]

Answer:

180 feet

Step-by-step explanation:

The length of each curtain = 48 inches. Let the length of the curtain in feet be represented by x.

But,

1 inch = 12 feet

So that,

48 inches = x feet

⇒ x = $\frac{48}{12}$

= 4

Thus,

48 inches = 4 feet

The number of feet of fabric needed for 45 curtains can be determined as:

45 x 4 feet = 180 feet

Therefore, 180 feet of fabric would be needed to make 45 curtains.
