Hi there! The most accurate way to estimate 23% of 70 is to write and solve a proportion. You would write it out as x/70 = 23/100, because we’re looking for the number that is 23% of 70. Cross multiply the values to get 1,610 = 100x. Divide each side by 100 to isolate the “x”. When you do, you get x = 16.1. There. 23% of 70 is 16.1.

Suppose that we wish to assess whether more than 60 percent of all U.S. households in a particular income class bought life insu

IceJOKER [234]

Answer:

A. 0.0049

B. Yes

Step-by-step explanation:

Sample proportion = 0.64

N = 1000

Population proportion = 0.60

We solve for standard deviation

= √p(1-p)/n

= √0.60(1-0.60)/1000

= √0.60x0.40/1000

= √0.00024

= 0.0155

The probability of sample >=0.64

Z>=0.64-0.60/0.0155

Z >= 0.04/0.0155

So z >= 2.5806

Using excel this equal to 0.0049

0.0049 is probability of sample proportion being 0.64 at least.

This answer in a shows that than 60% of households in the united states income class purchased life insurance last year.

Ami'yan runs every day for exercise at a rate of 1 kilometer every 15 minutes. How many meters does he run in 1 hour? - Thank yo

Alona [7]

Answer:

The total distance covered in 1 hour is 4000 meters.

Step-by-step explanation:

The distance Ami'yan runs is 15 minutes = 1 kilometer

Using the unit formula,

The distance ran in 1 minute = $(\frac{1}{15} ) \textrm{Kilometer}$

Now, 1 hour = 60 minutes

⇒The distance covered in 60 minutes = 60 x (Distance run in 1 minute)

= $60 \times \frac{1}{15} = 4$

So, the distance covered in 1 hour = 4 kilometer

1 kilometer = 1000 meters

⇒ 4 km = 4 x 1000 meters = 4000 m

Hence, the total distance covered in 1 hour = 4000 meters.
