Answer:

The answer is 8 r 3.

Step-by-step explanation:

When you multiply 4 by 8, you get 32. 32 would go in the two boxes below 35 so we can get thw remainder of 3. We get this because 35-32 is 3. The box below 32 would be the 3. Hope this helps :)

Are 0.34 and 3/4 equivalent? Please explain your answer In complete sentences.

insens350 [35]

No

when 3 divided by 4 is converted into a decimal, it is 0.75 which does not equal 0.34

0.34 can also be written as 34/100
and 3/4 can be written as 75/100

therefore 0.34 and 3/4 are not equivalent

<h3>What is a scale drawing?</h3>

A scale drawing is a smaller diagram of a larger image / building / object. The scale drawing is usually reduced at a constant dimension

<h3>What is the actual distance between the two cities?</h3>

The actual distance between the two cities = (22.5 X 4) / 3 = 30 miles

Determine the margin of error for a 90% confidence interval to estimate the population mean when s = 40 for the sample sizes bel

Ann [662]

Answer:

a) The margin of error for a 90% confidence interval when n = 14 is 18.93.

b) The margin of error for a 90% confidence interval when n=28 is 12.88.

c) The margin of error for a 90% confidence interval when n = 45 is 10.02.

Step-by-step explanation:

The t-distribution is used to solve this question:

a) n = 14

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 14 - 1 = 13

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 13 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.9}{2} = 0.95$ . So we have T = 1.7709

The margin of error is:

$M = T\frac{s}{\sqrt{n}} = 1.7709\frac{40}{\sqrt{14}} = 18.93$

In which s is the standard deviation of the sample and n is the size of the sample.

The margin of error for a 90% confidence interval when n = 14 is 18.93.

b) n = 28

27 df, T = 1.7033

$M = T\frac{s}{\sqrt{n}} = 1.7033\frac{40}{\sqrt{28}} = 12.88$

The margin of error for a 90% confidence interval when n=28 is 12.88.

c) The margin of error for a 90% confidence interval when n = 45 is

44 df, T = 1.6802

$M = T\frac{s}{\sqrt{n}} = 1.6802\frac{40}{\sqrt{45}} = 10.02$

The margin of error for a 90% confidence interval when n = 45 is 10.02.

You are dealth one card from a 52-card deck. find the probability that you are dealt a two or a black card

grigory [225]

The probability of getting a 2 or a getting a black card, find individual probabilities;

A standard deck has 52 cards.

There are 4 2's in a normal deck; probability of getting it is 4/25

The probability of getting a black card is; 26/52 since half the deck is red and black.

Now add up the probabilities since it says "or"

(4/52)+(26/52)=30/52 probability of the card that you were dealt being a two or a black card.

Hope I helped :)
