Answer:

$1,152 Mort will make if he sells 36 necklaces at the local art fair.

Step-by-step explanation:

Unit rates are expressed as the rates as a quantity 1 such that 4 miles per hour or 3 meter per seconds.

As per the given statement: Mort makes beaded necklaces that he sells for $32 each.

⇒ Unit rate per necklace = $32

It is also given that if he sells 36 necklaces at the local art fair.

by definition of unit rate;

\text{Total cost} = \text{Unit rate per necklace} \times 36

Substitute the given values we have;

\text{Total cost} = 32 \times 36 =\$ 1,152

Therefore, $1,152 Mort will make if he sells 36 necklaces at the local art fair.

if accrotime guarantees a full refund on any defective watch for 2 years after purchase, what percentage of total
adell [148]

Answer:

A. 0.62%

B. 28 months

Step-by-step explanation:

A. Calculation for what percentage of total production will the company expect to replace

Let x represents the distribution of life times

Let mean be 34 months

Let standard deviation be 4 months.

Based on the information the full refund on any defective watch for 2 years will represent 24 months (2 years *12 months).

First step

P(X<24)

= p(x-mean/ standard deviation< 24-34/4)

= p(z< -10/4)

=P(z<-2.5)

Second step is to Use the excel function to find NORMSDIST(z) of P(z<-2.5)

NORMSDIST(z)=0.62%

Therefore the percentage of total production will the company expect to replace will be 0.62%

B. Calculation for how much the guarantee period should be

First step

P(X<x)=0.06

P(x-Mean/Standard deviation < x-34/4) = 0.06

Second Step is to Use excel function

P(z<x-34/4) = (Normsinv(0.06)

x-34/4 = -1.555

Now let calculate how much the guarantee period should be

x = -6.22+34 months

x = 27.78

x = 28 months (Approximately)

Therefore the guarantee period should be 28 months

5<br> Find the slope of a line parallel to 2y - 6x+8.<br> -6
morpeh [17]

Answer:

Change the equation to the slope intercept form (y = mx + b)

2y = 6x + 8

Divide equation by 2

y = 3x + 4

Therefore

The line as a y intercept of 4

:

Parallel lines have the same slope;

Find the slope by putting in the equation in the point/intercept form

4x + 4y = 20

4y = -4x + 20

Divide equation by 4, results

y = -1x + 5

:

Now we know the slope (-1) and the y intercept (+4) if the line

y = -1x + 4

or just

y = -x + 4 is "the line"

Step-by-step explanation:
