(+)(-) → (-)

(+)(+) → (+)

(-)(-) → (+)

4 + (-2) - (-3) - 6 = 4 - 2 + 3 - 6 = 2 + 3 - 6 = 5 - 6 = -1

4+(-2) -(-3) -6

first of all we distribute the signs inside to simplify it for the first step

negative times positive = negative

and

negative times negative = positive

=4 -2 +3 -6

Now we can combine using PEMDAS rule

= 7 - 8

= -1

So the answer is -1

You bike for 2 hours at a speed no faster than 17.6 mph. Write an inequality that represents the possible number of miles you bi
Whitepunk [10]
Total no. of hours you spent biking = 2 hours
the speed at which you rode your bike ≤ 17.6 mph
Now,
We have,
speed =  \frac{distance}{time}

17.6 =  \frac{distance}{2}

17.6 *2=  distance

35.2=distance

So, you for given conditions, you can't travel more then 35.3 miles

So, the inequality for the given circumstances is:
x ≤ 35.2

ky has 3 times more books than grant and grant has 6 fewer books than Jaime if the total combined number of books is 176 how man
sergiy2304 [10]
Number of books each of them have:

Jaime: x
Grant: x - 6
Ky: 3 (x - 6)

There are 176 books in total, so we can write it down as:

176 = x + x - 6 + 3 (x - 6)
176 = x + x - 6 + 3 * x + 3 * (-6)
176 = x + x - 6 + 3x - 18
176 = 2x - 6 + 3x - 18
176 = 5x - 24                        / + 24 (both sides)
5x = 200                              / ÷ 5 (both sides)
x = 40

Doublecheck:

Jamie: 40
Grant: 40 - 6 = 34
Ky: 3 (40 - 6) = 3 * 34 = 102

102 + 34 + 40 = 176, so it's correct :)

PLEASE HELP ME
natulia [17]

<u>Answer:</u>  

Broker1 with $66.

Broker2 with $54.25

Broker4 with $50

Broker3 with $47.5

Broker5 with $33.5

<u>Explanation : </u>

Total number of shares Cindy have : 300

Market Price per share : $25  

Total price for the shares : 300 \times$25

                                        = $7500

Now ,

<u>Case 1: </u>

Commission provided by broker1 = 0.75%

Online fees provided by broker1 = $ 10

Total price provided by broker1= \frac{75}{10000}\times7500 +$10

                                                =$66.25

<u>Case 2:  </u>

Commission provided by broker2= 0.5%

Online fees provided by broker2=$17

Total price provided by broker2= \frac{5}{1000}\times 7500 + $17

                                                =$54.5

<u>Case 3: </u>

Commission provided by broker 3= 0.6% for 100 0r few  

Not applicable because  the total shares are 300

For over 100 shares

Commission provided= 0.5%

Online fees = $10

Total price =  \frac{5}{1000}\times 7500 + $10

                =$47.5

<u>Case 4: </u>

For more than 100 shares

Online fees for buying and sharing= $50

Total price = $50

<u>Case5 : </u>

Commision for a share bought or sold = 0.05%

Online fees =$30

Total Price= \frac{5}{10000}\times 7500 + $30

                 =$33.75

Suppose ACT Composite scores are normally distributed with a mean of 20.6 and a standard deviation of 5.2. A university plans to
zimovet [89]

Answer:

The minimum score required for admission is 21.9.

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 = 20.6, \sigma = 5.2

A university plans to admit students whose scores are in the top 40%. What is the minimum score required for admission?

Top 40%, so at least 100-40 = 60th percentile. The 60th percentile is the value of X when Z has a pvalue of 0.6. So it is X when Z = 0.255. So

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

0.255 = \frac{X - 20.6}{5.2}

X - 20.6 = 0.255*5.2

X = 21.9

The minimum score required for admission is 21.9.
