-3+8.

We know that the temperature /was/ -3, so it was 3 under zero. It has /risen/ by 8, meaning we have added 8 degrees to whatever the starting temperature was.

We can find out how much the temperature is right now: it was -3, went through -2, -1, 0, 1, 2, 3, 4, and now its at 5 degrees. Thats risen by 8 degrees, right? And -3+8 is the same as 8-3 (commutative property of addition, since we basically did 8+(-3)) which equals 5, so we know that we got the correct answer. :)

Ierofanga [76]

The reason why the number of failures and successes in two population proportions must be up to 10 is because it is important to have many of samples from both populations.

<h3>What is a Confidence Interval?
</h3>

This refers to the probability displayed that a parameter will exist between a pair of values around the mean.

It measures the extent to which one can be certain or uncertain about ones sampling method. Confidence Intervals are usually constructed using levels of 95% or 99%.

belka [17]

The lot is <u>9.2% of the an acre.</u>

<u>Given:</u>

Area of an acre = 4840 sq. yards

Area of lot = 40 by 100 ft = 40 ]\times 100 = 4,000 $ ft^{2}

Convert the area of the lot to feet (9 ft^{2} = yd^{2}):

<em>Therefore:</em>

Area of lot = \frac{4,000}{9} = 444.4 $ yd^{2}

Percentage occupied by the lot = area of lot / area of acre x 100

= \frac{444.4}{4840} \times 100\\\= 9.2

The lot therefore is <u>9.2% of the an acre</u>.

How many times does the digit 7 appear among the terms of the sequence of consecutive integer numbers 7, 8, 9, ...., 777?
Dahasolnce [82]

Answer:

234 times

Step-by-step explanation:

<u>Number of times the number 7 appears in a hundred</u>

7 as units digit (07-17-27 ..... 97): 10 times

7 as tens digit (70-71-72..... 79): 10 times

20 times the digit 7 appears in first one hundred (0-100)

Let's calculate how many times 7 would be as units or tens in 7 hundreds

20X7 = 140 times digit 7 appears until number 699

<u>Now, from 700 to 777</u>

7 as hundreds digit (700-701-702 .... 777): 78 times

7 as tens digit (770-771-772 .... 777): 8 times

7 as units digit (707-717-727....777): 8 times

78 + 8 + 8 = 94 times the digit 7 appears in the range 700 - 777. Plus 140 times

140 + 94 = 234 times
