Answer:
y = 14°
Step-by-step explanation:
since we can see it is an isosceles triangle so
base angles of isosceles triangle are equal then
2x = 50°
50° + 2x + 5y + 10° = 180° { being sum of angles of triangle }
50° + 50° + 5y + 10° = 180°
110° + 5y = 180°
5y = 180° - 110°
5y = 70°
y = 14°
Hope it will help :)

A bank auditor randomly selects 200 loans.
a) What are the mean and standard deviation of the proportion
of clients in this group who may not make timely payments?
Answers
Answer:
Step-by-step explanation:
Mean 0.7 and standard deviation 0.018
p = 0.07
n = 200
q = 1 - 0.07 which = 0.93
u = 0.07
o = (p * q) / n = [tex]\sqrt{(0.07)(0.93)/200}[/tex] = 0.018
Part B How many more questions would Kevin have to answer correctly to get more than 80% correct? Enter the number in the box.
Answers
Answer: See explanation
Step-by-step explanation:
Here's the complete question:
Kevin correctly answered 75% of his 32 test questions. how many questions would kevin have to answer to get more that 80% correct?
The number of questions he answered correctly will be:
= 75% × 32
= 75/100 × 32
= 3/4 × 32
= 24
He got 24 questions correctly.
To get more than 80% correctly, he will have to answer:
= 80% × 32
= 80/100 × 32
= 4/5 × 32
= 128/5
= 25.6 = 26
He will have to answer at least 26.

Answers
Answer:
V= 512 inches or, 42.67 feet
Step-by-step explanation:
So a cube has the same length on all sides so you would multiply length times with times area or V = a^3
So, 2/3 foot is equal to 8 inches so you would do V = 8^3 which would get you the answer,

The Patel family looks at map to plan their family vacation. They plan to travel from Smithville to Jonesville, which are 3 3/4 inches apart on the map. Then they plan to travel from Jonesville to Clarksville, which are 5 1/4 inches apart on the map. The scale on the map is 1/2 inch equals 4 miles. What is the actual distance the Patel family will travel by the time they reach Clarksville? Enter your answer in the box
Answers
Answer: 72 miles
Step-by-step explanation:
The total distance from Smithville to Clarksville will be:
= 3 3/4 + 5 1/4
= 9 inches
Since the scale on the map is:
1/2 inch = 4 miles
1 inch = 4 × 2 = 8 miles
Therefore, 9 inches will be:
= 9 × 8 = 72 miles
The actual distance that the Patel family will travel by the time they reach Clarksville will be 72 miles.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(5, 11) = 55. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 11 = 55. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - thirty-three fifths minus twenty-six elevenths = two hundred thirty-three fifty-fifths.

6 3/5 - 2 4/11 = 233/

Over a 24 hour period the temperature in a town can be modeled by one period of a sinusoidal function. The temperature measures 70*F in the morning, rises to a high of 80*F, falls to a low of 60*F, and then rises to 70*F by the next morning.
What is the equation for the sine function f(x), where x represents time on hours since the beginning of the 24 hour period that models the situation
Answers
Start with an initial temperature of T0 = 70° at t = 0 hours, and add to that a sine function that does the following, in order:
Rises by 10°, reaching 80° after 6 hours
Drops by 10º, reaching 70° after 12 hours
Drops by 10°, reaching 60° after 18 hours
Rises by 10°, reaching 70° after 24 hours
Note that the amplitude of the sine function is A = 10°.
T = period of the sine function
T = 24 hours
f(x) = T0 + A sin[(2π/T)x]
where
T0 = 70°
A = 10°
T = 24 hours
x = elapsed time in hours
f(x) = 70º + (10°)sin[(π/12)x]
with x in hours.
Test this solution and see that it fits the data. (Make sure your calculator is in the radian mode!)

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
In ΔFGH,
The measure of ∠H=90°, HG = 56, FH = 33, and GF = 65.
Now, By the formula;
⇒ cos θ = Base / Hypotenuse
Hence, We get;
⇒ cos G = GH / GF
⇒ cos G = 56/65
Thus, The value of ratio which represents the cosine of ∠G is,
⇒ cos G = 56/65
