Answer:

the answer is 23.75

Step-by-step explanation:

25 divide 100 = .25 ( to convert 5% into a decimal)

.25 x 5 = 1.25

25 - 1.25 = 23.75

(if correct pls give brainly :D, tysm luv <3 )

A line passes through the point (-9,3) and has a slope of -2/3?

saveliy_v [14]

The point-slope form:

$y-y_1=m(x-x_1)$

We have the slope m = -2/3 and the point (-9, 3). Substitute:

$y-3=-\dfrac{2}{3}(x-(-9))$

$y-3=-\dfrac{2}{3}(x+9)$ use distributive property

$y-3=-\dfrac{2}{3}x-\dfrac{2}{3}\cdot9$

$y-3=-\dfrac{2}{3}x-(2)(3)$

$y-3=-\dfrac{2}{3}x-6$ add 3 to both sides

$\boxed{y=-\dfrac{2}{3}x-3}$

April measured her bed and made a scale drawing. The scale of the drawing was 1

ser-zykov [4K]

Answer:

60 inches

Step-by-step explanation:

Given data

We have the scale of the drawing as

1cm= 6 inches

Now if 1 cm is equivalent to 6inches

then 10cm will be x inches

Cross multiply we have

x*1= 10*6

x= 60 inches

Hence the length of the actual bed is 60inches

Out of six computer chips, two are defective. If two chips are randomly chosen for testing (without replacement), compute the pr

Ratling [72]

Answer:

The probability that of the two chips selected both are defective is 0.1089.

Step-by-step explanation:

Let X = number of defective chips.

It is provided that there are 2 defective chips among 6 chips.

The probability of selecting a defective chip is:

$P(X)=p=\frac{2}{6}=0.33$

A sample of n = 2 chips are selected.

The random variable X follows a Binomial distribution with parameter n = 2 and p = 0.33.

The probability function of a Binomial distribution is:

$P(X=x)={n\choose x}p^{x}(1-p)^{n-x};\ x=0, 1, 2, ...$

Compute the probability that of the two chips selected both are defective as follows:

$P(X=2)={2\choose 2}(0.33)^{2}(1-0.33)^{2-2}=1\times 0.1089\times 1=0.1089$

Thus, the probability that of the two chips selected both are defective is 0.1089.

The sample space of selecting two chips is:

S = (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)

(2, 1), (2, 3), (2, 4), (2, 5), (2, 6)

(3, 1), (3, 2), (3, 4), (3, 5), (3, 6)

(4, 1), (4, 2), (4, 3), (4, 5), (4, 6)

(5, 1), (5, 2), (5, 3), (5, 4), (5, 6)

(6, 1), (6, 2), (6, 3), (6, 4), (6, 5)
