Answer:

4 hours

Step-by-step explanation:

6 × 2 = 12

12 ÷ 3 = 4

4 hours is the correct answer

Glad I could help:)

Answer:

x > -4

Step-by-step explanation:

What you do is in order to get the x by itself you need to do the opposite of -12 which is just +12 so you need to add 12 to both sides. You should end up with something like this:

x -12 + 12 < -16 + 12

x < -4

So, that should be your answer. Hope this helps :) Have a good day!!

Answer:

the "b" term is the term "-5 x" in the final quadratic expression

Step-by-step explanation:

Normally the "b" is the "linear term" in a quadratic equation.

So, perform the product of binomials and combine like terms to identify the final "b" term of the quadratic expression you get:

[tex](x-4)*(2x+3)=2x^2 +3x-8x-12=2x^2-5x-12[/tex]

Therefore the "b" term is the term "-5 x" in the final quadratic expression.

Step-by-step explanation:

The sum of the first four terms of the given sequence which is aₙ = (aₙ ₋ ₁)² is gotten as; 278

We are given the arithmetic sequence as;

a₁ = 2

aₙ = (aₙ ₋ ₁)²

We already have the first term. Thus;

Second Term;

a₂ = (a₂ ₋ ₁)²

a₂ = 2² = 4

Third Term;

a₃ = 4²

a₃ = 16

Fourth Term;

a₄ = 16²

a₄ = 256

Thus;

Sum of first four terms is;

S₄ = 2 + 4 + 16 + 256

S₄ = 278

Answer:

The median of the MCAT scores was of 500.

The first quartile of MCAT scores was of 492.845.

The third quartile of MCAT scores was of 507.155.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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 pvalue, we get the probability that the value of the measure is greater than X.

The mean score was 500.0 with a standard deviation of 10.6.

This means that [tex]\mu = 500, \sigma = 10.6[/tex]

Median:

In a normal distribution, the median is the same as the mean, so the median of the MCAT scores was of 500.

First quartile:

This is the 100*(1/4) = 25th percentile, which is X when Z has a pvalue of 0.25. So X when Z = -0.675.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.675 = \frac{X - 500}{10.6}[/tex]

[tex]X - 500 = -0.675*10.6[/tex]

[tex]X = 492.845[/tex]

The first quartile of MCAT scores was of 492.845.

Third quartile:

This is the 100*(3/4) = 75th percentile, which is X when Z has a pvalue of 0.75. So X when Z = 0.675.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.675 = \frac{X - 500}{10.6}[/tex]

[tex]X - 500 = 0.675*10.6[/tex]

[tex]X = 507.155[/tex]

The third quartile of MCAT scores was of 507.155.
