Answer:

(B) 4x^2y^2 + 5x + xy

Step-by-step explanation:

\dfrac{24x^3y^3 + 30x^2y + 6x^2y^2}{6xy}

6xy is a common factor.

= \dfrac{6xy(4x^2y^2 + 5x + xy)}{6xy}

6xy from numerator and denominator are canceled off.

= 4x^2y^2 + 5x + xy

Answer:

C, 4x²y² + 5x + 1

Step-by-step explanation:

to solve, we can first factor the numerator by finding a GCF.

\frac{24x^3y^3+30x^2y+6xy}{6xy}

the GCF of the numerator would be 6xy, as each term can be divided by 6xy. we have the following:

6xy(\frac{4x^2y^2+5x+1}{6xy})

we can cancel out the numerator and the denominator as both contain 6xy so we have the following:

4x²y² + 5x + 1

we cannot simplify this any further, so our answer is C

Cerrena [4.2K]

Answer:

113/24

Step-by-step explanation:

Simplify the following:

(14 + 1/8)/3

Put 14 + 1/8 over the common denominator 8. 14 + 1/8 = (8×14)/8 + 1/8:

((8×14)/8 + 1/8)/3

8×14 = 112:

(112/8 + 1/8)/3

112/8 + 1/8 = (112 + 1)/8:

((112 + 1)/8)/3

112 + 1 = 113:

(113/8)/3

113/8×1/3 = 113/(8×3):

113/(8×3)

8×3 = 24:

Answer: 113/24

Your sample is normally distributed with a mean age of 36. The standard deviation in this sample is 4 years. You would expect:
Nostrana [21]

Kindly find complete question attached below

Answer:

Kindly check explanation

Step-by-step explanation:

Given a normal distribution with ;

Mean = 36

Standard deviation = 4

According to the empirical rule :

68% of the distribution is within 1 standard deviation of the mean ;

That is ; mean ± 1(standard deviation)

68% of subjects :

36 ± 1(4) :

36 - 4 or 36 + 4

Between 32 and 40

2.)

95% of the distribution is within 2 standard deviations of the mean ;

That is ; mean ± 2(standard deviation)

95% of subjects :

36 ± 2(4) :

36 - 8 or 36 + 8

Between 28 and 44

3.)

99% is about 3 standard deviations of the mean :

That is ; mean ± 3(standard deviation)

99% of subjects :

36 ± 3(4) :

36 - 12 or 36 + 12

Between 24 and 48

Ilya [14]
Question #1
\frac{9}{25}=\frac{x}{120}\\\\120(9) = 25x\\\\1080 = 25x\\\\x= 43.2

For #1, the answer is 43.2

Question #2
\frac{6}{5} = \frac{2580}{x} \\\\2580(5) = 6x\\\\12900 = 6x\\\\x = 2150

For #2, the answer is 2150

A bowling leagues mean score is 197 with a standard deviation of 12. The scores are normally distributed. What is the probabilit
Bond [772]

Answer:

0.281 = 28.1% probability a given player averaged less than 190.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

A bowling leagues mean score is 197 with a standard deviation of 12.

This means that \mu = 197, \sigma = 12

What is the probability a given player averaged less than 190?

This is the p-value of Z when X = 190.

Z = \frac{X - \mu}{\sigma}

Z = \frac{190 - 197}{12}

Z = -0.58

Z = -0.58 has a p-value of 0.281.

0.281 = 28.1% probability a given player averaged less than 190.

write the slope - intercept equation of the line that passes through the point (6, "-1)" and has a slope of "-1/3"
TEA [102]

Answer:

y = - \frac{1}{3} x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - \frac{1}{3} , then

y = - \frac{1}{3} x + c ← is the partial equation

To find c substitute (6, - 1 ) into the partial equation

- 1 = - 2 + c ⇒ c = - 1 + 2 = 1

y = - \frac{1}{3} x + 1 ← equation of line
