Its 1000 x 1.75 = 1750 feet of cord. She didnt need to do anything else. Just multiply.

Solve each system by graphing, check your answer<br><br> Y=3x+13<br> Y=x-3

MA_775_DIABLO [31]

Answer:

x = -8

Y = -11

Step-by-step explanation:

Given

Y = 3x + 13

Y = x - 3

Substitute x - 3 for Y in the first equation

We have

Y = 3x + 13

x - 3 = 3x + 13

Add 3 to both sides

x - 3 + 3 = 3x + 13 + 3

x = 3x + 16

Subtract 3x from both sides

x - 3x = 3x - 3x + 16

-2x = 16

Divide both sides by -2

x = 16/-2

x = -8

Now substitute -8 for x in any of the above equations to get Y.

Using the second equation, we have

Y = x - 3

Y = -8 - 3

Y = -11

Light bulbs manufactured at a certain factory have a 3% probability of being defective. what is the probability that 5 out of a

lbvjy [14]

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. The probability that 5 out of a shipment of 30 will be defective is 0.001617.

<h3>What is Binomial distribution?</h3>

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,

P(x) = ⁿCₓ pˣ q⁽ⁿ⁻ˣ⁾

Where,

x is the number of successes needed,

n is the number of trials or sample size,

p is the probability of a single success, and

q is the probability of a single failure.

The probability of the bulb being defective is 3%(0.03) and the probability of the bulb not being defective is 97%(0.97).

Now, it is needed to be found that the probability that 5 out of a shipment of 30 will be defective can be written as,

P(x) = ⁿCₓ pˣ q⁽ⁿ⁻ˣ⁾

P(x=5) = ³⁰C₅ (0.03)⁵ (0.97)²⁵

P(x=5) = 0.001617

Hence, the probability that 5 out of a shipment of 30 will be defective is 0.001617.

Select the correct answer. This table shows information on types of fragrances sold to men and women in a day at a beauty supply

maria [59]

Answer: C. 27% of men like woody fragrances, and 45% of the people who like citrus fragrances are women

Step-by-step explanation:

Here, Given table,

Citrus Fruity Woody

Men : 27 21 18

Women : 22 26 15

Thus, The percentage of men like woody fragrances

= $\frac{\text{Number of men who like woody fragrance}}{\text{total number of Men}} \times 100$

= $\frac{18}{66}\times 100$

= $\frac{1800}{66}$

= 27.2727..... %

≈ 27 %

Now, The percentage of men like woody fragrances

= $\frac{\text{Number of women who like citrus fragrance}}{\text{total number of persons who like citrus}} \times 100$

= $\frac{22}{49}\times 100$

= $\frac{2200}{49}$

= 44.8979591837 %

≈ 45 %

Thus, Option C is correct.

Four equivalent forms of a quadratic function are given. Which form displays the zeros of function h?OA. (X) = -2(2x - 8)OB.h(x)

Setler79 [48]

The form of quadratic representing the roots can be expressed as,

$h(x)=a(x-p)(x-q)$

Where p and q are the roots of the equation.

The form which represents the zeroes of function h is,

$h=-4(x-)(x+2)$

Where 2 and -2 are the roots of the function h(x).

Thus, option (B) is correct.
