The diameter of a circular table top is 2.6 metres. What is it’s circumference to the nearest metre?

1 answer:

7 0

Hoi!

To calculate the circumference, we use the formula $C = \pi d$

Plug in the values.

$C = \pi * 2.6$
$8.2 = \pi * 2.6$

Your answer to the nearest meter is 8.

Mileage tests are conducted for a particular model of automobile. If a 98% confidence interval with a margin of error of 1 mile

kipiarov [429]

Answer: 37

Step-by-step explanation:

As per given description in the question, we have

Population standard deviation : $\sigma=2.6\text{ miles per gallon}$

Critical value for 98% confidence interval = $z_{\alpha/2}=2.33$

Margin of error : E= 1 mile per gallon

Formula we use to find the sample size :

$n=(\dfrac{z_{\alpha/2}\cdot \sigma}{E})^2$

i.e. $n=(\dfrac{(2.33)\cdot(2.6)}{1})^2$

$\Rightarrow\ n=36.699364\approx37$

Therefore , the number of automobiles should be used in the test =37

6³ ÷ 4 + 2 x 9(32 x 8 – 17 x 4).

inn [45]

ANSWER

3438

EXPLANATION:

PARENTHESIS FIRST

32 x 8 = 256

17 x 4 = 68

256 - 68 = 188

(now the equation is, 6³ ÷ 4 + 2 x 9 (188))

EXPONENTS NEXT

6³= 216

(now the equation is, 216 ÷ 4 + 2 x 9 (188))

MULTIPLICATION AND DIVISION NEXT (left to right)

216 ÷ 4 = 54

2 x 9 = 18

18 x 188 = 84

(now the equation is, 54 + 3384)

LASTLY ADDITION AND SUBTRACTION (left to right)

54 + 3384 = 3438

Ta-da!
