Answer:

a=250, \ b=10

Step-by-step explanation:

a=\frac{5\cdot10^2}2=\frac{5\cdot100}2=\frac{500}2=250\\ b=\frac{2\cdot10^2\cdot(10-5)}{10\cdot10}=\frac{2\cdot100\cdot5}{100}=\frac{1000}{100}=10

Hi there!

Find the value of a and b when x = 10.

-------------------------------------------------------

Let's solve A:

a = \frac{5(10)^2}{2}

a = \frac{5 * 100}{2}

a = \frac{500}{2}

a = 250

-------------------------------------------------------

Let's solve B:

b = \frac{2(10)^2(x(10)-5)}{10(10)}

b = \frac{2(100)(5)}{100}

b = \frac{200 * 5}{100}

b = \frac{1000}{100}

b = 10

-------------------------------------------------------

Hope This Helps :)

-7x-6y=-1

Cancel something
we cancel x's

multiply 1st equation by 5 and 2nd by 7 and add them
-35x-30y=-5
<u>35x-28y=7 +</u>
0x-58y=2

-58y=2
divide both sides by -58
y=-1/29
sub back
5x-4(-1/29)=1
5x+4/29=1
minus 4/29 from both sides
note, 1=29/29
5x=25/29
divide bot sides by 5 (or times 1/5)
x=5/29


(5/29,-1/29)

An accelerated life test on a large number of type-D alkaline batteries revealed that the mean life for a particular use before
zheka24 [161]

Answer:

68.2% of the batteries failed between 17.8 and 20.2 hours.

95.44% of the batteries failed between 16.6 and 21.4 hours.

99.97% of the batteries failed between 15.4 and 22.6 hours.

Step-by-step explanation:

The 68-95-99.7 states that, for a normally distributed sample:

68.26% of the measures are within 1 standard deviation of the sample.

95.44% of the measures are within 2 standard deviations of the sample.

99.97% of the measures are within 3 standard deviations of the sample.

In this problem, we have that:

Mean of 19 hours, standard deviation of 1.2 hours.

About 68.26% of the batteries failed between what two values?

This is within 1 standard deviation of the mean. So 68.2% of the batteries failed between 17.8 and 20.2 hours.

About 95.44% of the batteries failed between what two values?

This is within 2 standard deviations of the mean. So 95.44% of the batteries failed between 16.6 and 21.4 hours.

About 99.97% of the batteries failed between what two values?

This is within 3 standard deviations of the mean. So 99.97% of the batteries failed between 15.4 and 22.6 hours.
