Complete question :

The average amount that a college student spends on a textbook is $205 with a

standard deviation of $35. What is the probability that a student spends:

A. between $10 and $310?

Answer:

0.999

Step-by-step explanation:

Mean, m = 205 ; Standard deviation, s = 35

Z = (x - m) / s

x = 310

Z = (310 - 205) / 35 = 3

P(z < 3) = 0.99865

x = 10

Z = (10 - 205) / 35 = - 5.57

P(Z < - 5.5)

P(z < 3) - P(z < - 5.5)

0.99865 - 0

= 0.999

2x - 8y = 6

-2x + 2y = 7

Add the two equations together by combining like terms:

2x + -2x = 0

-8y + 2y = -6y

and 6 + 7 = 13

So when you combine the terms you end up having:

-6y = 13

Now solve for y by dividing each side by -6:

y = 13/-6

Rewrite by moving the negative sign in front of the fraction to get

y = -13/6

The answer is C.

Solve for y in the two equations below using substitution.

Equation 1 ➢ 2x - 8y = 6

Equation 2 ➢ -2x + 2y = 7

Adding both equations together, by combining similar terms, We get,

When we combine the terms, We get,

⇒ -6y = 13

Now, solving for y, by divide Right Hand Side & Left Hand Side by -6, We get,

⇒ y = [tex] \sf \frac{13}{-6} [/tex]

⇒ y = [tex] \sf \frac{-13}{6} [/tex]

∴ The value of y is [tex] \bf \frac{-13}{6} [/tex]

The value of y is [tex] \bf \frac{-13}{6} [/tex]

Hence, Option C. [tex] \bf \frac{-13}{6} [/tex] is correct answer.

4.88

Step-by-step explanation:

I used my calculator to do this;

I did stat and I put in the numbers, I clicked calculate and it said the answer was 4.875. Round that to the nearest hundredth and you'll get 4.88.

Answer:

4.88

Step-by-step explanation:

The actual mean is 4.88 to the nearest hundredth. She either approximated the sum of elements to 40 instead of 39 or she approximated the actual mean to the nearest whole number.

I think she gave an approximated average or a rounded average, but I am not sure.

Mark as Brainliest

Answer: 40% chance

Sample space: 3 white 2 red, 5 pairs

2/5 probability, as a percent would be 40% chance

The probability that Jeff will grab a red pair of socks is 0.4.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Three pairs are white and the other 2 pairs are red. Therefore, the probability that Jeff will grab a red pair of socks is,

Probability = 2/5 = 0.4

Hence, the probability that Jeff will grab a red pair of socks is 0.4.

Answer:

[tex]m =13[/tex]

Step-by-step explanation:

Given

The attached dataset

Required

The mean absolute deviation

First, calculate the mean

[tex]\bar x = \frac{\sum x}{n}[/tex]

So, we have:

[tex]\bar x = \frac{42+40+39+76+71+55+68+65}{8}[/tex]

[tex]\bar x = \frac{456}{8}[/tex]

[tex]\bar x = 57[/tex]

The mean absolute deviation (m) is:

[tex]m =\frac{1}{n} \sum|x - \bar x|[/tex]

So, we have:

[tex]m =\frac{1}{8} (|42 - 57| + |40 - 57| + |39 - 57| + |76 - 57| + |71 - 57| + |55 - 57| + |68 - 57| + |65 - 57|)[/tex]

Using a calculator, we have:

[tex]m =\frac{1}{8} (|-15| + |-17| + |-18| + |19| + |14| + |-2| + |11| + |8|)[/tex]

Remove absolute bracket

[tex]m =\frac{1}{8} (15 + 17 + 18 + 19 + 14 + 2 + 11 + 8)[/tex]

[tex]m =\frac{1}{8} *104[/tex]

[tex]m =13[/tex]

The mean absolute deviation is 13

Answer: 18.75 inches

Step-by-step explanation:

Let the height of the model be represented by x. Therefore, based on the information given in the question, we can form an equation which will be:

3/x = 32/200

Cross multiply

32 × x = 200 × 3

32x = 600

x = 600/32

x = 18.75

Therefore, the height of the model is 18.75 inches

Answer:

45

Step-by-step explanation:

Because it's face values

If it was place values then it would be 5000 x 90 but since its face values it is 5 x 9 as face values is the number itself

Answer:

La masa del recipiente vacío es 1,2146 kg.

Step-by-step explanation:

La densidad se define como la propiedad que tiene la materia, ya sean sólidos, líquidos o gases, para comprimirse en un espacio determinado. En otras palabras, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia. Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:

[tex]densidad= \frac{masa}{volumen}[/tex]

Entonces la masa puede ser expresada como:

masa= densidad*volumen

En este caso:

Reemplazando:

masa= 1000 [tex]\frac{kg}{m^{3} }[/tex] * 7,854*10⁻⁴ m³

masa=0.7854 kg

Si la masa del recipiente lleno es de 2 kg, entonces se le resta la masa de agua calculada:

2 kg - 0,7854 kg= 1,2146 kg

Entonces, la masa del recipiente vacío es 1,2146 kg.

Given:

The function is:

[tex]f(x)=x^3-4x^2-37x+40[/tex]

[tex]f(8)=0[/tex]

To find:

The all of the zeros of f(x) algebraically.

Solution:

We have, [tex]f(8)=0[/tex] is means 8 is a zero of given function and (x-8) is a factor of given function.

The function is:

[tex]f(x)=x^3-4x^2-37x+40[/tex]

Spittle the middle terms in such a way so that we get (x-8) as a common factor.

[tex]f(x)=x^3-8x^2+4x^2-32x-5x+40[/tex]

[tex]f(x)=x^2(x-8)+4x(x-8)-5(x-8)[/tex]

[tex]f(x)=(x^2+4x-5)(x-8)[/tex]

Spittle the middle term of the quadratic expression, we get

[tex]f(x)=(x^2+5x-x-5)(x-8)[/tex]

[tex]f(x)=(x(x+5)-1(x+5))(x-8)[/tex]

[tex]f(x)=(x+5)(x-1)(x-8)[/tex]

For zeros, [tex]f(x)=0[/tex].

[tex](x+5)(x-1)(x-8)=0[/tex]

[tex](x+5)=0\text{ and }(x-1)=0\text{ and }(x-8)=0[/tex]

[tex]x=-5\text{ and }x=1\text{ and }x=8[/tex]

Therefore, the all zeros of the given function are -5, 1 and 8.
