Mathematics

Answer:

If a is 1.. we substitute one in every a in g(a)

4 * 1 + 16

4+ 16 = 20

g(a)= 20

f(20)

-16 + 20 = 4

and 4/4 = 1

so f (g (a)) = a

Find X, and the two angle measures.
Snowcat [4.5K]

Answer:

x = -4

m<LMP = 77°

m<NMP = 103°

Step-by-step explanation:

Straight angles by definition have a total measure of 180°.

This means that m<LMP and m<NMP are 180° together.

Therefore m<LMP + m<NMP = 180°.

[substitution property]

(-16x + 13)° + (-20x + 23)° = 180°

[associative property of addition]

(-36x + 36)° = 180°

-36x + 36 = 180

–36 –36

-36x = 144

÷-36 ÷-36

x = -4

_________________

Since m<LMP = (-16x + 13)°.

Using substitution with x = -4:

m<LMP = (-16(-4) + 13)° = (64 + 13)° = 77°.

Since m<NMP = (-20x + 23)°.

Using substitution with x = -4:

m<NMP = (-20(-4) + 23)° = (80 + 23)° = 103°.

This is true because 77° + 103° = 180°.

Two more than the product of a number and 8 is 5
Andreyy89
When ever the problem says is, the next number after that is going to be the answer to the equation. So now you have =5.

Next it say two more which means adding so now we have, +2=5

Now we have the product of a number and 8. This means that the number and 8 equal the product. Now we know that an answer that is a product is a multiplication problem. That means that you have to multiply 8 and the number.

That leaves us with the answer, n•8+2=5

If a variable has a distribution that is​ bell-shaped with mean 28 and standard deviation 5​, then according to the Empirical​ R
mars1129 [50]

Answer:

99.7% data lies between 13 to 43

Step-by-step explanation:

Mean:  \mu = 28

Standard deviation : \sigma = 5

68% of data lies between \mu - \sigma to \mu +\sigma

95% of the data lies between \mu - 2\sigma to \mu +2\sigma

99.7% data lies between  \mu - 3\sigma to \mu +3\sigma

We are supposed to find  99.7 of the data will lie between which​ values

99.7% data lies between  28 - 3(5) to 28 +3(5)

99.7% data lies between  13 to 43

Hence 99.7% data lies between 13 to 43
