the measures of the angles of a triangle are shown below .solve for x ​

Answers

Answer:

x=17

Step-by-step explanation:

The equation is 44+60+(4×+8)=180

X=17
There are 180 degrees in a triangle.
You subtract the other whole angles in the triangle to 180 degrees.
Also you have to subtract 8 because that is the only whole number in the equation.
Divide your answer by the slope, or 4.
Then you get 17.

Emma earned $120 babysitting. She saved 44% of his money. How much money did she save?

Answers

Answer:

$52.80

Step-by-step explanation:

First off we need to find out how much she didn't save (to make it easier)

$120 - 44% = $67.20

Well how much did she save? Lets subtract $67.20 from $120 to find our answer.

$120 - $67.20 = $52.80

Emma saved $52.80 (44%).

Given : ABCD is a rectangle
m∠B1DB = 60°, m∠ADB = 45°
DB1=37
Find: Volume

Answers

Answer:

Step-by-step explanation:

∠B₁DB = 60°

△B₁BD is a 30°-60°-90° triangle. The sides are in the ratio 1:√3:2

B₁D = 37 ⇒ BD = 37/2 = 18.5

BB₁ = 18.5√3

△ABD is isosceles

AB = AD = BD/√2 = 18.5/√2

volume = AB × AD × BB₁

= (18.5/√2) × (18.5/√2) × 18.5√3

= 18.5³√3/2

≅ 5483 cubic units

Answer:

Answer: x = y = 2√7

Step-by-step explanation:

x = (2√14)cos45

x = (2√14)½√2

x = √14(√2) = √28 = 2√7

y = (2√14)sin45

y = (2√14)½√2

y = √14(√2) = √28 = 2√7

What is the slope of a line parallel to the line whose equation is 6x -2y= 32. Fully simplify your answer

Answers

Step-by-step explanation:

Given equation is

6x -2y= 32.........i)

Slope of line I) is

[tex]m1 = \frac{ - x \: coefficient}{y \: coefficient} \\ = \frac{ - 6}{ - 2} \\ = 3[/tex]

Now

As it is said that the lines are parallel so slope, m1 = m2

So the slope of a line parallel to line I) is

= 3

A standard weight known to weigh 10 grams. Some suspect bias in weights due to manufacturing process. To assess the accuracy of a laboratory scale,that weight is weighed repeatedly. The scale readings are normally distributed with unknown mean. The population standard deviation of the scale readings is known to be 0.0003 gram.
(a) The weight is weighed FIVE times. The mean result is 10.0044 grams. Give a 98% confidence interval for the mean weight. Please keep 5 decimals in your answer.
(
,
)

(b) How many measurements must be averaged to get a margin of error of +/- 0.0001 with 98% confidence? Your answer must be a whole number.

Answers

Answer:

a) The 98% confidence interval for the mean weight is between 10.00409 grams and 10.00471 grams

b) 49 measurements are needed.

Step-by-step explanation:

Question a:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.98}{2} = 0.01[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.01 = 0.99[/tex], so Z = 2.327.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.327\frac{0.0003}{\sqrt{5}} = 0.00031[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 10.0044 - 0.00031 = 10.00409 grams

The upper end of the interval is the sample mean added to M. So it is 10 + 0.00031 = 10.00471 grams

The 98% confidence interval for the mean weight is between 10.00409 grams and 10.00471 grams.

(b) How many measurements must be averaged to get a margin of error of +/- 0.0001 with 98% confidence?

We have to find n for which M = 0.0001. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.0001 = 2.327\frac{0.0003}{\sqrt{n}}[/tex]

[tex]0.0001\sqrt{n} = 2.327*0.0003[/tex]

[tex]\sqrt{n} = \frac{2.327*0.0003}{0.0001}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.327*0.0003}{0.0001})^2[/tex]

[tex]n = 48.73[/tex]
