This triangle is an iscoceles, how can I (or we) tell?? Well, the angles of a triangle always add up to 180° and we know the angles of 2 corners, 90° and 45° so we can do this to find the last angle where "c" is the unknown corner:
180 - (90 + 45) = c
180 - 135 = c
45 = c
so "c" is also equal to 45° so we can decisively conclude that this figure is an iscoceles triangle.
How to find x:
Use the pythagorean theorem
c = √a² + b²
Then calculate using that equation
c = √7² + 7²
c = 9.9
In this case "c" is for the length of hypotenus but the image asks for x so
x = c
and
c = 9.9
so
x = 9.9
Hope this helps!

Does anyone know how to find the measure of this missing angle ?
Answers
Answer:
x=57
Step-by-step explanation:
x+28+x+38=180
Step 1: Simplify both sides of the equation.
x+28+x+38=180
(x+x)+(28+38)=180(Combine Like Terms)
2x+66=180
2x+66=180
Step 2: Subtract 66 from both sides.
2x+66−66=180−66
2x=114
Step 3: Divide both sides by 2.
2x/2=114/2
Answer:

A researcher is interested in determining the average number of years employees of a company stay with the company. If past information shows a standard deviation of 7 months, what size sample should be selected so that at 95% confidence the margin of error will be 2 months or less?
Answers
Answer:
48
Step-by-step explanation:
The significance level is 95%
Z-alpha/2 = 1.96 at 0.05 from the standard normal distribution table.
The standard deviation has been given to be 7
Margin of error is 2
We solve further using the formula:
n = (z-alpha/2 * sd/ME)²
n = (1.96 * 7/2)²
n = (1.96x3.5)²
= 6.86²
= 47.0596
This is approximately
n = 48
So the sample size they should be selected should be 48 for at 95% confidence level.
Estimation for 2 1/3 divided by 1/3

Answer:
7 because u are changing division to mutiplication its called replicate
Answer:
since 2 and 1/3 is a mixed number change it into an improper fraction so it will be 7/3 / 1/3 find the reciprocal of the second fraction that is one of the three the reciprocal will be 3/1 so it will be 7/3 * 3/1 because when you find the reciprocal of a second fraction you also find the reciprocal of the sine and in this case division will change to multiplication when you multiply it you'll get the answer to be 7 hope it helps

The members of a band are arranged in a rectangular formation. When they are arranged in 8 rows, there are 2 positions unoccupied in the formation. When they are arranged in 9 rows, there are 3 positions unoccupied. How many members are in the band if the membership is between 100 and 200
Answers
Answer:
150
Step-by-step explanation:
Using 8 rows leaves 2 positions unoccupied implies that the population of the number of members in the band is 2 less than a multiple of 8. That makes this an even number.
Similarly, we understand that the number of members is 3 less than a multiple of 9. So, If we list the even numbers that are 3 less than multiples of 9 between 100 and 200 and are even; we have:
117 – 3, 135 – 3, 153 – 3, 171 – 3, 189 – 3
= 114, 132, 150, 168, 186
Also, the numbers that are two less than a multiple of 8:
102, 110, 118, 126, 134, 142, 150, 158, 166, 174, 182, 190, 198
From above, we will realize that the number common in both is 150
Let's check if that satisfy our calculation;
SO:
150/8 = 18 remainder 6 ; Thus 8 - 6 = 2 (positions)
150/9 = 16 reminder 6 ; Thus 9 - 6 = 3 (positions)
Hence the number of members in the band if the membership is between 100 and 200 is 150

In a small city, approximately 15% of those eligible are called for jury duty in any one calendar year. People are selected for jury duty at random from those eligible, and the same individual cannot be called more than once in the same year. (a) What is the probability that a particular eligible person in this city is selected in both of the next 2 years
Answers
Answer:
0.0225
Step-by-step explanation:
Probability that an eligible individual is called for jury duty in any one calendar year = 15/100 = 0.15
a) What is the probability that a particular eligible person in this city is selected in both of the next 2 years
Probability that an eligible person is chosen in each of the next 2years:
P(being chosen in first year) * P(being chosen in second year)
Since the probability of being chosen is the same in any one year with a probability of 0.15
Hence,
P(being chosen in first year) * P(being chosen in second year)
0.15 * 0.15 = 0.0225
a. the probability that a particular eligible person in this city is selected in both of the next 2 years is 0.0225
Calculation of the probability:Since In a small city, approximately 15% of those eligible are called for jury duty in any one calendar year and there is two years.
So, the probability is
= 0.15 (0.15)
= 0.0225

you have observed that the average size of a particular goldfish is 1.5 inches long. the standard deviation of the size of the goldfish is 0.25 inches. approximately what is the size of a goldfish such that only 16 percent of the goldfish are smaller from such size
Answers
Answer:
The 16 percent of the goldfish are smaller from 1.25 inches.
Step-by-step explanation:
Let X denote the size of a particular goldfish.
It is provided that the mean size is, μ = 1.5 inches and standard deviation of the size is, σ = 0.25 inches.
Assume that X is normally distributed.
Compute the size of a goldfish such that only 16 percent of the goldfish are smaller from such size as follows:
P (X < x) = 0.16
⇒ P (Z < z) = 0.16
The z-value for such a probability is:
z = -0.99
*Use a z-table.
Compute the value of x as follows:
[tex]z=\frac{x-\mu}{\sigma}\\\\-0.99=\frac{x-1.5}{0.25}\\\\x=1.5-(0.99\times 0.25)\\\\x=1.2525\\\\x\approx 1.25[/tex]
Thus, the 16 percent of the goldfish are smaller from 1.25 inches.
