If UT = 31.6, what is the measure of US?
Given:
UT = 31.5
To find:
The measure of US.
Solution:
In the figure, WV bisects UT.
⇒ US = ST -------------- (1)
UT = US + ST
31.6 = US + US (using (1))
31.6 = 2 US
Divide by 2 on both sides.
[tex]$\frac{31.6}{2} =\frac{2US}{2}[/tex]
[tex]15.8=US[/tex]
The measure of US is 15.8.

Step-by-step explanation:
This is correct
Answer:
Step-by-step explanation:
Let's start by figuring out what the new balance is each time the balance changes, and the number of days with that balance. Then we can take the mean of those balances.

find the value of x in the triangle, 60°, 60°, 5x
The value of x in the expression for the angle of the triangle is 12.
What is the value of x in the triangle?The figure in the image is a triangle.
From the image:
Angle 1 = 5x
Angle 2 = 60 degrees
Angle 3 = 60 degrees
Note that, the sum of the interior angle of a triangle equals 180 degrees.
To determine the value of x, add the 3 angles and equate to 180 degrees.
Hence:
5x + 60 + 60 = 180
Collect and add like terms:
5x + 120 = 180
Subtract 120 from both sides:
5x + 120 - 120 = 180 - 120
5x = 180 - 120
5x = 60
x = 60/5
x = 12
Therefore, x has a value of 12.

A certain insecticide kills 60% 60 % of all insects in laboratory experiments. A sample of 7 insects is exposed to the insecticide in a particular experiment. What is the probability that exactly 4 insects will survive? Round your answer to four decimal places.
Answer: The probability that exactly 4 insects will survive = 0.2903.
Step-by-step explanation:
Given : The proportion of all insects in laboratory experiments killed by insecticide = 60%=0.60
Since , by using insecticide only two outcomes are possible either it kills or not kills , so we can use binomial.
Sample size of insects = 7
By using binomial probability formula : [tex]P(x)=^nC_xp^x(1-p)^{n-x}[/tex], where x is binomial variable , n = sample size and p is the probability of getting success.
Let x be the number of insects survived.
As per given , we have
n=7 , p=0.60
Now , the probability that exactly 4 insects will survive :
[tex]P(x=4)= ^7C_4(0.60)^4(1-0.60)^3\\\\=\dfrac{7!}{4!3!}(0.60)^4(0.40)^3\\\\= 35\times 0.1296\times 0.064 \\\\=0.290304\approx0.2903[/tex]
Hence, the probability that exactly 4 insects will survive = 0.2903

Mrs. Alexander wants to make a rectangular quilt that will have an area of 80 square feet So far, she has made 16
squares for the quilt each 2 feet long and 2 feet wide. Does she have enough squares to complete the quilt?
No, she doesn't have enough square to complete the quilt. Mrs. Alexander need 4 more squares to complete the rectangular quilt, that will have an area of 80 square feet. 20 square required to make quilt.
Step-by-step explanation:
The given is,
Area of an rectangular quilt - 80 square feet
She made 16 squares
Square have 2 feet long and 2 feet wide
Step:1
Area of rectangular quilt = 80 square feet
Area of 16 squares = 16 × Area of square..................(1)
Formula for area of square,
[tex]A = a^{2}[/tex]................................(2)
Where, a - Sides of square
a = Length = Wide
From given,
a = 2 feet
Equation (2) becomes,
[tex]A = 2^{2}[/tex]
A = 4 square feet
Equation (1) becomes,
Area of 16 squares = 16 × 4
= 64 square meters
Area of rectangular quilt ≠ Area of 16 squares
80 ≠ 64
Area of square is less compare to area rectangular quilt, so we need more square,
Required amount of square area = 80 - 64
= 16 square feet
Required amount of squares = [tex]\frac{16}{4}[/tex]
= 4 squares
Total(16+4) square areas = 20 × 4 = 80 square feet
Area of rectangular quilt = Area of 20 squares
80 square feet = 80 square feet
Result:
No, she doesn't have enough square to complete the quilt. Mrs. Alexander need 4 more squares to complete the rectangular quilt, that will have an area of 80 square feet. 20 square required to make quilt.

The heights of 1000 students at a local school were recorded and found to be approximated by the normal curve below. Which answer could represent the mean and standard deviation for these data ?
Answer:
The mean of the distribution of heights of students at a local school is 63 inches and the standard deviation is 4 inches.
Step-by-step explanation:
The normal curve approximating the distribution of the heights of 1000 students at a local school is shown below.
For a normal curve, the mean, median and mode are the same and represents the center of the distribution.
The center of the normal curve below is at the height 63 inches.
Thus, the mean of the distribution of heights of students at a local school is 63 inches.
The standard deviation represents the spread or dispersion of the data.
From the normal curve it can be seen that values are equally distributed, i.e. the difference between two values is of 4 inches.
So, the standard deviation is 4 inches.

The intensity of an earthquake with a magnitude of 2 is how many times greater than the intensity of an a standard earthquake ?
Answer:
The intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of a standard earthquake.
Explanation:
The magnitude of earthquakes is given by
[tex]Magnitude=log\frac{I}{S}[/tex]
[tex]2=log\frac{I}{S}\\[/tex]
Where I is the intensity of earthquake and S is the intensity of standard earthquake.
The magnitude of standard earthquakes is given by
[tex]Magnitude=log\frac{S}{S}= log(1) = 0[/tex]
So comparing the magnitude of the given earthquake and standard earthquake,
[tex]log\frac{I}{S} = log\frac{S}{S}[/tex]
[tex]log\frac{I}{S} - log\frac{S}{S}[/tex]
[tex]log(2) - log(1)[/tex]
[tex]2 - 0[/tex]
[tex]2[/tex]
which means that
[tex]10^2 = 100[/tex] times greater
Therefore, the intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of a standard earthquake.

To find Ilana's average speed, we divide the total laps by the total minutes, which results in one-fourth of a lap per minute.
Explanation:To find the average speed, we divide the total distance by the total time taken
To determine Ilana's average speed, we need to divide the total distance (2 laps) by the total time (8 minutes). When we do that, we get 0.25 laps per minute.
This is also known as one-fourth of a lap per minute. That means, on average, Ilana completes a quarter of a lap every minute.
