1 answer:

8 0

To write 215% as a decimal you can approach the problem two ways. You can divide 215 by 100. 215/100 = 2.15 You can also move the decimal two places to the left 215.0 = 2.15 To write 2.15 as a fraction you will place 215 over 100. {215/100}. You will then want to write this fraction in it’s simplest form. The greatest common denominator is 5 so you will then divide the numerator and denominator by 5. 215/5 = 43 100/5 = 20 215/100 = 43/20 To write this fraction as a mixed fraction you would divide 43 by 20. 43 ÷ 20 = 2 with a remainder of 3 This is written as: 2 3/20

Step-by-step explanation:

ΔJLK = ΔNLM ( vertically opposite Δ)

ΔJKL = ΔNML ( each 90° )

so,

triangle JKL = triangle NML (by AA similarity)

JK / KL = NM / ML

JK / 21m = 42m / 49m

JK = 42 × 21 ÷ 49

JK = 18m

Answer:

The true statement about Kendra's sample is:

b) Kendra's samples are precise but not accurate.

Step-by-step explanation:

a) Data and Calculations:

Average age of dogs currently alive = 4.8 years

Average ages of dogs in Kendra's sample

Week Average Age (in years)

1 3.7

2 3.8

3 4.2

4 4.1

5 3.9

6 3.9

7 4.0

Total 27.6

Mean = 3.9 (27.6/7)

b) Accuracy refers to how close Kendra's sample mean age of dogs is to the average age value as stated in the Modern Dog Magazine. While the Magazine stated an average age of 4.8 years, Kendra's sample produced a mean of 3.9 years. On the other hand, precision refers to how close Kendra's sample measurements are to each other. With a mean of 3.9 years, the sample measurements are very close to each other. Therefore, we can conclude that "Kendra's samples are precise but not accurate."

There is 3/4 of pizza leftover from the night before . how many 1/8 portions are there

serg [7]

We want to know how many 1/8's are in 3/4, so we divide.

$\sf\dfrac{3}{4}\div\dfrac{1}{8}$

Flip the 2nd fraction and multiply:

$\sf\dfrac{3}{4}\times\dfrac{8}{1}$

Multiply the numerators and denominators together:

$\sf\dfrac{3\times8}{4\times1}\rightarrow\dfrac{24}{4}$

Divide:

$\boxed{\sf6}$
