What is the measure of the missing angle?
Answer:
B=23.19
Step-by-step explanation:
First, find the last side of the triangle using the Pythagorean theorem.
[tex]a^{2} +b^{2} =c^{2} \\21^{2} +9^{2} =c^{2} \\441+81=c^{2} \\\sqrt[3]{58}=c[/tex]
Then, find the missing angle, lets name it B.
The angle B can be found using the inverse sine function.
B=arcsin(opp/hyp)
[tex]B=arcsin(\frac{9}{\sqrt[3]{58} } )\\B=23.19[/tex]

You want to walk from home to a grocery store that is3/4 miles away. You stop for a rest after 5/8 miles. How much farther do you have to walk?
Write your answer as a fraction in simplest form.
Answer:
1/8 miles
Step-by-step explanation:
You have to subtract [tex]\frac{3}{4}- \frac{5}{8}[/tex] for the answer.
First, you gotta make 3/4 have a common denominator.
To do this multiply 3/4 by 2/2 (2/2 equals one, so value isn't changed.)
and you get 6/8.
Then you can subtract 6/8 - 5/8 to get 1/8 miles.
And there's no need to simplify 1/8.
The function f gives the weekly profit, in thousand dollars, that an airline makes on its flights from Boston to Washington D.C. when the ticket price is p dollars. Interpret the following.
f'(70) = 1.5
When the ticket price is _____, the weekly profit to the airline on flights from Boston to Washington is _____
Answer:
When the ticket price is $70, the weekly profit to the airline on flights from Boston to Washington is $1500.
Step-by-step explanation:
The function has the following format:
f(p)
That is, f is a function of p.
The derivative, f'(p), is the variation of f for the given value of p.
f'(70) = 1.5
p = 70, thus, ticket price of $70.
f'(70) = 1.5 means that the weekly profit to the airline on flights from Boston to Washington is 1.5 thousand dollars, that is, $1500.
Thus the correct answer is:
When the ticket price is $70, the weekly profit to the airline on flights from Boston to Washington is $1500.
Twice Henry's earnings increased by 10 is $253. Therefore, Henry earned $____
Answer:
121.50
Step-by-step explanation:
Let x be the earnings
2x+10 = 253
Subtract 10 from each side
2x+10-10 = 253-10
2x = 243
Divide by 2
2x/2 = 243/2
x = 121.50
1/3 x 1/2 x 1/4 = V.
Answer:
Step-by-step explanation:
1*1*1/3*2*4=V
1/24=V
multiply all numerator and all denominator.

What is side e
Angle d and angle f
Please let me know asap
9514 1404 393
Answer:
e ≈ 9.608D ≈ 46.5°F ≈ 38.5°Step-by-step explanation:
The only given angle is between the two given sides, so the Law of Cosines must be used to find the side opposite the angle. It tells you ...
e² = d²+f² -2df·cos(E)
e² = 7² +6² -2·7·6·cos(95°) ≈ 92.321082
e ≈ 9.608
The remaining angles can be found from the law of sines.
sin(D)/d = sin(E)/e
D = arcsin(d/e·sin(E)) ≈ arcsin(7/9.608·sin(95°)) ≈ 46.5°
F = 180° -95° -46.5° = 38.5°

Sonya has a collection of gold and silver coins.
65% of her collection consists of gold coins.
70 of her coins are silver.
What is the total number of coins in Sonya's collection?
Enter your answer in the space provided.
HELP PLEASE
Answer:
10.5
Step-by-step explanation:
65% of 70 is 45.5
So gold is 45.5 and silver is 54.5
so but45.5 + 54.5 = 100% but divide by 2
which is 50% but now we find 10% and 5%
10% = 7
5% = 3.5
now add 7 and 3.5 together
7+3.5 = 10.5

Answer:
a) 42
b) 42/120
Step-by-step explanation:
Oof, I was just about done with answering this question but I deleted it all by accident so I had to rewrite it.
Anyways, the first part of it is correct.
The second part of it is a bit harder. See, this is conditional probability, which uses the equation that I've attached below.
For Event A, you'll need the total boys / total students:
0.44166
For Event B, you'll need the total counters / total students:
0.83333
Now, plug these values into the equation. The weird U thingy is called "Union". It basically means "and".
P(A and B) / P(B)
P(0.44166 * 0.8333) / P(0.8333)
0.36803 / 0.8333
This is about 0.44165, or 53/120

The equation shown below represents a logarithmic equation of base b.
a = logb(c)
Which set of numbers can a represent?
A.Only numbers > 0
B. Only numbers < 0
C All real numbers except 0
DAll real numbers
Answer:
C. All real numbers except 0
Step-by-step explanation:
It is the same as " numbers > 0"
Option (A) is correct.
What is logarithmic equation?"This equation will have all the terms but one be a logarithm and the one term that doesn’t have a logarithm will be a constant. In order to solve these kinds of equations we will need to remember the exponential form of the logarithm".
For the given situation,
The logarithmic equation, [tex]a = logb(c)[/tex]
⇒[tex]b^{c} = a[/tex]
Where a>0 , b>0 and b!=1
Thus a can represent, only numbers > 0.
Hence we can conclude that option (A) is correct.

A manufacturer considers his production process to be out of control when defects exceed 3%. In a random sample of 100 items, the defect rate is 4% but the manager claims that this is only a sample fluctuation and production is not really out of control. At the 0.01 level of significance, test the manager's claim.
Answer:
The p-value of the test is of 0.2776 > 0.01, which means that the we accept the null hypothesis, that is, the manager's claim that this is only a sample fluctuation and production is not really out of control.
Step-by-step explanation:
A manufacturer considers his production process to be out of control when defects exceed 3%.
At the null hypothesis, we test if the production process is in control, that is, the defective proportion is of 3% or less. So
[tex]H_0: p \leq 0.03[/tex]
At the alternate hypothesis, we test if the production process is out of control, that is, the defective proportion exceeds 3%. So
[tex]H_1: p > 0.03[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.03 is tested at the null hypothesis
This means that [tex]\mu = 0.03, \sigma = \sqrt{0.03*0.97}[/tex]
In a random sample of 100 items, the defect rate is 4%.
This means that [tex]n = 100, X = 0.04[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.04 - 0.03}{\frac{\sqrt{0.03*0.97}}{\sqrt{100}}}[/tex]
[tex]z = 0.59[/tex]
P-value of the test
The p-value of the test is the probability of finding a sample proportion above 0.04, which is 1 subtracted by the p-value of z = 0.59.
Looking at the z-table, z = 0.59 has a p-value of 0.7224
1 - 0.7224 = 0.2776
The p-value of the test is of 0.2776 > 0.01, which means that the we accept the null hypothesis, that is, the manager's claim that this is only a sample fluctuation and production is not really out of control.
A ladder is leaning against the side of a 10cm house. If the base of the ladder is a 3cm away from the house, how tall is the Ladder
Answer:
10.44cm lon
Step-by-step explanation:
Given data
Height of house= 10cm
Distance of ladder from wall= 3cm
We can apply the Pythagoras theorem to get the length of the ladder
Also, the length of the ladder is the hypothenuse
z^2= x^2+y^2
z^2= 10^2+ 3^2
z^2= 100+9
z^2= 109
square both sides
z= √109
z= 10.44cm
Hence the ladder is 10.44cm long
