About 250 million drivers are registered in the United States. While on a trip with her family, a student counted the number of
Lilit [14]
She could estimate that there would be about 148 million female drivers.

From her data, she found there were 118 females drivers out of the total 200 drivers that she counted.

That is 118 out of 200 or 0.59 or 59%.

Now, just take 59% of 250.

0.59 x 250 = 147.5 which rounds to 148.

Find r if (r, 6) and (5, -4) are two points on a line with a slope of 5/7 (Hint: use the slope formula)
andreyandreev [35.5K]

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have

(r,\ 6),\ (5,\ -4)\\\\m=\dfrac{5}{7}

Substitute

\dfrac{-4-6}{5-r}=\dfrac{5}{7}\\\\\dfrac{-10}{5-r}=\dfrac{5}{7}\qquad|\text{cross multiply}\\\\5(5-r)=(-10)(7)\qquad|\text{use distributive property}\\\\25-5r=-70\qquad|-25\\\\-5r=-95\qquad|:(-5)\\\\\boxed{r=19}

Choose as many answers as apply.
alexandr1967 [171]

Answer:

  • multiplying a multi-digit number by itself several times (finding the power of a number)
  • finding a square root
  • statistical calculations

Step-by-step explanation:

We don't know what your introduction tells you, but the above-listed operations are ones I choose to use a calculator for. I also use a calculator for ordinary arithmetic, such as division by numbers with 2 digits or more. (It is simply faster and requires no scratch paper.)

If statistical calculations are not done with a calculator, they at least require the availability of suitable tables.

___

All of these operations can be done by hand without a calculator, and were in times passed. Lifetimes of effort were involved in generating some of the original math tables for statistics, trig, logarithms, and other functions readily evaluated using a modern calculator.
