a certain triangle has a 30 angle and a 60 angle which must be a true statement about the triangle
Answer:
the other side has an 90° angle , it must be an acute triangle
Step-by-step explanation:
a triangle has a total angle of 180°
So if one side has an angle of 60° and the other has an angle of 30°, the other side must be the substraction of both angles to the 180° sum
180° - 60° - 30° = 90°
Answer: The longest side is twice as long as the shortest side.

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?
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.

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
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.

Does anyone know how to find the measure of this missing angle ?
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:
x=57
Answer:
57
Step-by-step explanation:
x+28+x+38=180
2x+66=180
-66 -66
2x=114
/2 /2
x=57

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

Pythagorean Theorem:a2 + b2 = c2
Re−write the formula solving for b2 .
Answer:
b^2=c^2-a^2
Step-by-step explanation:
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
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

Write the equation of the line:
(1,-7); slope =-1
Answer:
y=-1x-6
Step-by-step explanation:
the slope is -1
use y=mx+b
Plug the point into y=mx+b, -7=-1(1)+b
-7=-1+b
add 1 both sides the y- intercept is b=-6

Write an equation of a line with the given slope and y-intercept.
m = 4, b = -1
a. y = -x + 4
b. y = 4x + 1
C. y = -x - 1
d. y = 4x - 1
Please provide explanation :)
Answer:
D. y=4x-1
Step-by-step explanation:
y=mx+b (This is the slope intercept formula) The M(X) represents the slope and the B represents the y intercept.
y=4x-1
Answer:
d. y = 4x -1
Step-by-step explanation:
y = mx + b
m= 4
b= -1
y = (4)x + (-1)
y = 4x - 1

The solution to -2x/3 + 7< 15 is the set ? A x>-12 B x<-12 C x>33 D x<-10
Answer:
A. x>-12
Step-by-step explanation:
-2x/3+7<15 Subtract 7 on both sides.
-7 -7
-2x/3<8 -2x/3 is equal to -2/3x, so you can simplify to that.
-2/3x<8 Because you have to isolate x, multiply by the reciprocal of the
*-3/2 *-3/2 fraction. This will divide by -2/3 on both sides.
x>-12 Remember, because you multiplied by a negative, you have to flip the inequality sign.
Hope this helps you! Have a nice day c:
