2 answers:

7 0

360 to 30 can be written as 360:30 and call also be written as 360/30

$\frac{360}{30} = \frac{36 \times 10}{3 \times 10}= \frac{36}{3} = \frac{12 \times 3}{1 \times 3} = \frac{12}{1}$

360 to 30 simplified can be expressed as a ratio like 12:1, 12 to 1, or 12/1

I think it's 12:1 ? Well ratios are easy to do, but seriously I'm still not sure which number comes first ( like the 1 or the 12 ) . I just learned it.

Simplify complex fraction 3/4 + 1/3/1/6 + 3/4

Arturiano [62]

= (3/4 + 1/3)/(1/6 + 3/4)
= (3/4 + 1/3)/(1/6 + 3/4)
Multiply numerator and denoiminator by 12
=12(3/4+1/3) / 12(1/6 + 3/4)
= (3*3 + 1*4) / (2 + 3*3)
= 13/11

Identify the vertex f(x) = 3(x - 2) 2square + 11

scoray [572]

Answer:

Step-by-step explanation:

Vertex form of a quadratic equation is: y = a(x - h)² + k, where point (h, k) is the vertex

f(x) = 3(x - 2)² + 11

This is in vertex form, so the vertex is (2, 11)

*it's positive 2 because we are subtracting h in the equation, and we are subtracting positive 2 in our problem

The average waiting time for a drive-in window at a local bank is 9.2 minutes, with a standard deviation of 2.6 minutes. When a

Lady bird [3.3K]

Answer:

a) 56.91% probability that the customer will have to wait between 5 and 10 minutes.

b) 65.49% probability that the client will have to wait less than 6 minutes of more than 9 minutes.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 9.2, \sigma = 2.6$

(a) Between 5 and 10 minutes

This is the pvalue of Z when X = 10 subtracted by the pvalue of Z when X = 5. So

X = 10

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

$Z = \frac{10 - 9.2}{2.6}$

$Z = 0.31$

$Z = 0.31$ has a pvalue of 0.6217

X = 5

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

$Z = \frac{5 - 9.2}{2.6}$

$Z = -1.62$

$Z = -1.62$ has a pvalue of 0.0526

0.6217 - 0.0526 = 0.5691

56.91% probability that the customer will have to wait between 5 and 10 minutes.

(b) Less than 6 minutes or more than 9 minutes

Less than 6

pvalue of Z when X = 6

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

$Z = \frac{6 - 9.2}{2.6}$

$Z = -1.23$

$Z = -1.23$ has a pvalue of 0.1230

12.30% probability that the client will have to wait less than 6 minutes

More than 9

1 subtracted by the pvalue of Z when X = 9.

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

$Z = \frac{9 - 9.2}{2.6}$

$Z = -0.08$

$Z = -0.08$ has a pvalue of 0.4681

1 - 0.4681 = 0.5319

53.19% probability that the client will have to wait more than 9 minutes

Less than 6 or more than 9

12.30 + 53.19 = 65.49% probability that the client will have to wait less than 6 minutes of more than 9 minutes.

9-5 1/2 x - 3 (-2x+1)

Stells [14]

First, distribute the -3(-2x + 1).
-3 x -2x = 6x -3 x 1 = -3 -3(-2x + 1) = 6x - 3
Now we have:
9 - 5 1/2x + 6x - 3
Combine like terms.
-5 1/2x + 6x = 1/2x 9 - 3 = 6
The two terms we are left with are 1/2x and 6.
The simplified version of this expression is 1/2x + 6.
Hope this helps!

Event A is "rolling a 5 on a six-sided die" and event B is "rolling an odd number on the same die." Are the events dependent or

Lerok [7]

The probability of rolling a 5 and rolling an odd number on a die is independent; rolling a 5 does not influence the probability of rolling an odd number the next time.

King or Jack is mutually exclusive; they cannot both happen at the same time.
Club or Queen is not mutually exclusive; they can happen at the same time.
King or Ace is mutually exclusive; they cannot both happen at the same time.
