sheila is 155 cm tall lilias height is 10 cm less than twice sheila's height. how tall is lilia?​

Answer:

w = 12

Step-by-step explanation:

-3(2-5w) = 9w + 66

Complete the parenthesis:

-6 + 15w = 9w + 66

Switch the numbers and group them with like terms;

15w - 9w = 66 + 6

6w = 72

w = 12

Answer:

The point estimate for the population proportion of successes is 0.35.

Step-by-step explanation:

The point estimate for the population proportion of successes is the sample proportion of successes(number of successes divided by the size of the sample).

A sample of 60 results in 21 successes.

[tex]\pi = \frac{21}{60} = 0.35[/tex]

The point estimate for the population proportion of successes is 0.35.

Answer:

  (x, y) = (2, 5)

Step-by-step explanation:

Substitute the expression for y in the second equation into the first equation:

  5x -5 = x +3

  4x = 8 . . . . . . add 5-x to both sides

  x = 2 . . . . . . divide by 4

  y = 2+3 = 5 . . . substitute for x in the first equation

The solution is (x, y) = (2, 5).

Answer:

For significance levels lower than 0.07, the null hypothesis would be rejected.

Step-by-step explanation:

Decision regarding the null hypothesis:

The decision depends on the p-value of the test.

If the p-value of the test is less than the significance level, the null hypothesis is reject.

If the p-value of the test is more than the significance level, the null hypothesis is not reject.

The analyst reported a p-value of 0.07. For what significance level of will the null hypothesis would be rejected?

From the theory above, for significance levels lower than 0.07, the null hypothesis would be rejected.

Answer:

D. √176 cm

Step-by-step explanation:

Were given a right triangle.

PQ = 7 cm

QR = 15 cm

To find the length of side PR, apply Pythagorean theorem, which is c² = a² + b²

Where,

c = hypotenuse/longest side = 15 cm

a = PR

b = 7 cm

Thus:

15² = PR² + 7²

225 = PR² + 49

225 - 49 = PR²

176 = PR²

√176 = PR

PR = √176 cm

Answer:

640g

Step-by-step explanation:

1000m=1km so 125m times x= 2km x is 16 so we multiply 16 by 40 to get 640 g

The mass of 2 km long yarn ball is 640.

A measure of how much matter is in an object. This gold bar is quite small but has a mass of 1 kilogram (about 2.2 pounds), so it contains a lot of matter.

Given

40 g ball of yarn is 125 m long

To find mass for 2 km = 2000 m long yarn

[tex]\frac{40}{125} \ 2000[/tex]   =   [tex]\frac{80000}{125}[/tex]    =     640g

Hence, The mass of 2 km long yarn ball is 640.

Answer:

x = 46

Step-by-step explanation:

Since the angle that is not marked is a vertical angle, is must be the same in each triangle

The sum of each triangle is 180, set them equal and subtract the same angle from each side, this leaves the equation

53+85 = x+92

138 = x+92

138-92 =x

46 =x

C. 11.60 ounces to 12.60 ounces

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean 12.10, standard deviation 0.25.

In which range will the amount of water dispensed be found 95% of the time?

By the Empirical Rule, within 2 standard deviations of the mean. So

12.10 - 2*0.25 = 12.10 - 0.5 = 11.60

12.10 + 2*0.25 = 12.10 + 0.5 = 12.6

So the correct answer is given by option C.

Orca Correct, Sea Star Wrong. Heart it if it was helpful :D

Step-by-step explanation:

11-4=7. Orca correct.

Sea star...11-4=7

Wrong its 7, not -7

Answer:

The orca is right and the sea star is wrong.

If you were to add 11 to -4, it would no longer be a negative number.

You take four out of 11 which would bring it to a zero. There would be 7 left, therefore the answer being a positive 7.
