Step-by-step explanation:

For Q 1 : 25 % of the scores are below this value. The area under the bell-shaped curve of the normal distribution is 0.25. And since we have 288 electricians that took a certification test:

Anyone know how to do these?
erastovalidia [21]

Answer:

B. 1/m¹⁸

Step-by-step explanation:

To simplify the equation, we start with the values inside the brackets.

Therefore  m⁻¹m⁵ results to m⁴.

This is because the sign between the m⁻¹ and m⁵ is multiplication, and when multiplying figures that have a similar base, we add the indices.

that is, -1+5=4

then we divide m⁴ by m⁻², that is, m⁴/m⁻²=m⁶

To divide figures that have the same base we subtract the powers.

That is, 4-(-2)=6

the resulting expression from inside the brackets will be (m⁶)³ which results to m⁻¹⁸ which is the same as 1/m¹⁸

Begin by clearly stating the problem; you can copy this from the problem set file. Show how you solved the problem step by step,
Y_Kistochka [10]

Answer: 13%

Step-by-step explanation:

The formula to find the simple interest is given by :-

I=Prt, where P is the principal amount, r is rate of interest () in decimal and t is the time ( in years).

Given : P = $19,100 ,  I=$9932.00  and t=  4 years

Substitute all the above values in the formula , we get

9932.00=(19100)r(4)\\\\\Rightarrow\ r=\dfrac{9932}{19100\times4}\\\\\Rightarrow r=\dfrac{13}{100}=0.13

In percent , r=0.13\times100=13\%

Hence, the rate of interest = 13%

Use place value to find the product 5 x 70 = 5 x. Tens
Mekhanik [1.2K]
Well x will need to equal 70 because if u do 70 x 5 it will be 350 so u will need to divide that by 5x and u will get x=70
