9514 1404 393

Answer:

  8 lb

Step-by-step explanation:

The original weight W increased by 12% is ...

  W + 12%·W = 8.96

  1.12W = 8.96

  W = 8.96/1.12 = 8.00

The kitten's weight a month ago was 8.0 pounds.

Complete the explanation of why it is possible to draw more than two different rectangles with an area of 100 square units, but
Marysya12 [62]

Answer:

100 has <u>5</u> factor pairs, so that many different rectangles can be drawn. 15 only has <u>2</u> factor pairs, so only that many different rectangles can be drawn.

Explanation:

there are 5 pairs of whole numbers that multiplied together will be 100:

  1. 100 x 1 = 100
  2. 50 x 2 = 100
  3. 25 x 4 = 100
  4. 20 x 5 = 100
  5. 10 x 10 = 100

while there are only 2 pairs of whole numbers that multiplied together will be 15:

  1. 15 x 1 = 15
  2. 3 x 5 = 15

Direct mail advertisers send solicitations​ ("junk mail") to thousands of potential customers in the hope that some will buy the
harina [27]

Answer:

The interval is (.0817, .118).

Step-by-step explanation:

Let's make this interval! The easy way is to go to STAT->TEST->A, 1-prop z-int, but I will show the long way.

<u>1. Conditions</u>

First we must check the conditions.

<em>Randomization condition: </em>The sample is given to be random, so we can assume independence.

<em>Success/failure condition: </em>Both np>10 and nq>10 must be met.

  • np = 1030(103/1030) = 103 ✓
  • nq = 1030(927/1030) = 927 ✓

<em>10% condition: </em>The sample cannot be greater than 10% of the population.

  • 10n < N, 10(1030) < 200000 ✓

All conditions are met, so we can use <u>a 1-proportion z-interval</u> to represent the data.

<u></u>

<u>2. Mechanics</u>

<u>Find </u>\hat{p}<u>, the sample proportion.</u>

103/1030 = .1

\hat{q}, then, the probability of not p, is 1 - .1 = .9

<u>Find z* (z star), the critical z-value.</u>

You can do this on your calculator using 2nd->VARS->3 (or you can memorize it - it's 1.96. Winky face.) This is called the invNorm function, that takes the left side area under the normal curve. But what do we plug in to the invNorm function?

invNorm(.975) = 1.96

<u>Plug values into the equation.</u>

\hat{p} ± z*\sqrt{\frac{\hat{p}\hat{q}}{n} }

.1 ± 1.96\sqrt{\frac{.1*.9}{1030} }

.1 ± 1.96(.00935)

.1 - .0183 = .0817

.1 + .0183 = .118

(.0817, .118)

<u>3. Conclusion</u>

Based on this sample, we are 95% confident that the proportion of people the company contacts who may buy something is between .0817 and .118. That isn't very likely, but maybe they'll make a little profit!

a man paid $8000 for a car since then ,its value has fallen by 25% calculate the current value please help me​
Anna [14]

Answer:

$6000

Step-by-step explanation:

so basically, 25% of the 100% value is gone, right? which means that 75% of the value would remain. After that, all is easy. 8000*0.75, since 75% is 0.75, and the answer of that is 6000, so the current value is 6000 dollars.
