Step-by-step explanation:

In a parallelogram, alternate angles are equal, so

[tex]\left \{ {{3x-8=4y+7} \atop {4x+13=5x-12}} \right.[/tex]

From the latter equation we obtain [tex]x= 13 + 12 = 25[/tex]. So substituting in the former equation gives

[tex]75-8 = 4y + 7\\4y = 60\\y = 15[/tex]

A store is instructed by corporate headquarters to put a markup of 25​% on all items. An item costing ​$16 is displayed by the store manager at a selling price of ​$4. As an​ employee, you notice that this selling price is incorrect. Find the correct selling price. What was the​ manager's likely​ error?

Answers

Answer:

$20

Step-by-step explanation:

the manager's error could likely be putting the percentage mark up rather than the markup price added to the original price

25%×16

= $4

mark up price= (16+4)$

= $20

Suppose that a box of 86 circuits is sent to a manufacturing plant. Of the 86 circuits shipped, 5 are defective. The plant manager receiving the circuits randomly selects 2, without replacement, and tests them. If both circuits work, the manager will accept the shipment. Otherwise the shipment is rejected. What is the probability that the shipment is accepted

Answers

Answer:

the probability that the shipment is accepted is 0.8865

Step-by-step explanation:

Given the data in the question;

N = 86,  n/d = 5 and n = 2

now, without replacement

the probability that the shipment is accepted will be;

probability that the shipment is accepted = probability that non is defectives

so p( non is defective ) = ( (86-5)/86) × ((86-5-1)/(86-1))            

p( non is defective ) =  ( 81 / 86) × (80/85)

p( non is defective ) =  0.8865

Therefore, the probability that the shipment is accepted is 0.8865

Suppose that a balanced, six-sided die has been altered so that the faces are 1, 2, 3, 4, 5, and 5. If the die is tossed five times, and the number on the uppermost face is recorded each time, what is the probability that the numbers recorded are 1, 2, 3, 4, and 5 in any order

Answers

Answer:

0.0309

Step-by-step explanation:

Faces on dice ( 1, 2, 3, 4, 5, 5)

Number of outcomes = 6

With 5 repeated twice

P(event A) = Required outcome / Total possible outcomes

Required outcome :

Number of 5's = 2 * distinct faces!

Required outcome = 2 * 5! = 2 * 120 = 240

Total possible outcomes = (number of faces)^distinct Numbers = 6^5 = 7776

Required / total possible = 240 / 7776

= 0.0308641

= 0.0309

Given f(x) = 7x^9, find f^-1 (x). Then state whether f^-1 (x) is a function

Answers

A though without graphing software it would appear to be C


Step-by-step explanation:
The inverse of a function is the function reflected across the line y=x. This results in the coordinate points (x,y) of the function becoming (y,x) for the inverse function. Algebraically to find the inverse, switch the x and y locations and solve for y.
y = 7x^9
x = 7y^9
x/7 = y^9
(9)√(x/7) = y
This is a ninth root of (x/7) also written in exponents as y = (x/7)^(1/9).
This is a function. While it appears not to be a function because the middle portion over the origin appears vertical, it is a function because the middle portion over the origin is changing and graphing software shows it has no input with more than one output. Without graphing software you would rule it is not a function.

When you multiply a given fraction by a factor greater than 1, the product will (always, sometimes, never) be less than the given fraction

Answers

9514 1404 393

Answer:

  sometimes

Step-by-step explanation:

For positive numbers, multiplying by a factor greater than 1 increases their value:

  (1/2) × 2 = 1 > 1/2

For negative numbers, multiplying by a factor greater than 1 decreases their value:

  (-1//2) × 2 = -1 < -1/2

So, "sometimes" the product will be less than the given fraction.

An investment service is currently recommending the purchase of shares of Dollar Department Store selling at $18 per share. The price is approximately normally distributed with a mean of 20 and a standard deviation of 2. What is the probability that in a year the shares will be selling: Between $21 and $24

Answers

Answer:

0.2857 = 28.57% probability that in a year the shares will be selling between $21 and $24

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 price is approximately normally distributed with a mean of 20 and a standard deviation of 2.

This means that [tex]\mu = 20, \sigma = 2[/tex]

What is the probability that in a year the shares will be selling between $21 and $24

This is the pvalue of Z when X = 24 subtracted by the pvalue of Z when X = 21. So

X = 24:

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

[tex]Z = \frac{24 - 20}{2}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a pvalue of 0.9772

X = 21:

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

[tex]Z = \frac{21 - 20}{2}[/tex]

[tex]Z = 0.5[/tex]

[tex]Z = 0.5[/tex] has a pvalue of 0.6915

0.9772 - 0.6915 = 0.2857

0.2857 = 28.57% probability that in a year the shares will be selling between $21 and $24
