Answer: 9 (with a margin of: 0)

Step-by-step explanation:

Times everything by 5

That gives you 15 + 10w = 105.

Subtract 15 from both sides

Divide by 10 to get w by itself

Then you solve

Rewrite 6/9 fraction two different ways

valkas [14]

2/3 (simply simplify/divide them by 3)
Or
.66666 (basically repeating numbers)
Or
66.6 % (Make sure for the decimal or percentage you write a line above the 6 after the 1st number behind the decimal to show it as a repeating number!)

Lavita finally got her beautiful painting done it was a total of 1 2/3 meters. She was able to finish 3/8 each week. how many we

Paul [167]

<u>Answer:</u>

4 weeks

<u>Explanation:</u>

Length of Lavita’s painting = $1 \frac{2}{3} m=\frac{5}{3} m$

Length she was able to finish each week= $\frac{3}{8}m$

Now,

If she is able to finish $\frac{3}{8}m$ in 1 week

Then

$\frac{3}{8}m$ = 1 week

1 m = $\frac{8}{3}m$ week

Therefore

$\frac{5}{3} m=\frac{8}{3} \times \frac{5}{3} \text { week }$

= $\frac{40}{9}$ week

=4.44 week

= 4 weeks (approx.)

Television sizes are determined by the length of their diagonal measure. Michael just bought a new television. The height of the

julsineya [31]

Answer:

Step-by-step explanation:

The height of the television is 40 inches and the length is 71.5 inches.

Part A

The part of the right angle triangle that you have been given are the legs which are also the opposite and adjacent sides. You are looking for the hypotenuse

Part B

The Pythagorean theorem is expressed as

Hypotenuse² = opposite side² + adjacent side²

The equation becomes

Hypotenuse² = 40² + 71.5²

Part C

Length ² = 1600 + 5112.25

Length ² = 6712.25

Length = √6712.25

Length = 81.9 inches

Part D

The size of the television is 82 inches

Suppose 44% of the students in a university are baseball players. If a sample of 736 students is selected, what is the probabili

zaharov [31]

Required probability is 0.8990

Given that,

p = 0.44

1 - p = 0.56

n = 736

$\mu_\hat{p}} = p = 0.44\\\sigma_\hat{p}} = \frac{p*(1-p)}{n} = \sqrt(\frac{0.44*0.56)}{736} ) =$ 0.01830

Converting Normal distribution to standard normal because A normal distribution is determined by two parameters the mean and the variance. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. Hence it's easy to work with standard normal distribution.

P(0.14< $\hat{p}$ <0.47) = P((0.41-0.44)/0.01830) < $\frac{\hat{p} - \mu _{\hat{p}} }{\sigma _{\hat{p}} }$ <(0.47-0.44)/0.01830

Using normal algebra we get:

= P(-1.64 < z < 1.64)

= P(z < 1.64) - P(z < -1.64)

= 0.9495 - 0.0505

= 0.8990

Thus, required probability is 0.8990
