If FE is a midsegment of BCD, find BC.
A.
3.8
B.
6.9
C.
8.7
D.
13.8
AND CAN YOU EXPLAIN IT ALSO THANK YOU
Answer:
D
Step-by-step explanation:
The side BC is bisected at E by the midsegment FE , then
BE = EC = 6.9 , so
BC = BE + EC = 6.9 + 6.9 = 13.8 → D
In aclassroom 5/6 of the students are wearing blue shirts and 2/5 are wearing white shirts there are 36 students in the class how many students are wearing a shirt other than blue or white
Blue shirt - 5/6
White shirt - 2/5
Total students - 36
So the answer is
5/6 of the students wearing blue shirts out of 36 are 30.
2/5 (i.e 4/10) of the students wearing white shirts out of 36 are 24.
Remaining 5/6 students are wear shirts other than blue or white are 30.

How do you determine the value of the unknown exponent in the
equation 9,700 divided by 10 to the power of what equals 0.97?
Answer:
?=4
Step-by-step explanation:
First, we have to tell how we got from 9700 to 0.97. so we know that it is divided by 10^?. When you divide by 10, it is the same as moving the decimal point one space to the left. SO all you have to do is count how many times the decimal point got moved to get from 9700 to 0.97. This number is 4 so the question mark is 4 because 9700/10^4 will move the decimal place 4 to the right and give you 0.97.
Ay 4 function is represented by the equation y = 2(x + 1). Complete the table and graph for the function. Does the quation represent a linear function? Explain your reasoning. (2 oints) N -4 -2 2 4 -2 4 Input -2 -1 0 1 Output
Use point (-3,2):
2 = 4*(-3) + b
b = 2 +12

A coin is tossed and an eight-sided die numbered 1 through 8 is rolled Find the probability of tossing a head and then rolling a number greater than 1 The probability of tossing a head and then rolling a number greater than 1 is (Round to three decimal places as needed.)
Answer:
Step-by-step explanation:
Probability of a head is 1/2 of getting heads.
probability of a number greater than 1 is 7/8 on 8 sided die
Total probability = 1/2 * 7/8 = 7/16 = 0.4375

For x-intercepts, y is zero y = x² - 12x + 32 then x-intercept is (8,0) and (4,0)
For x-intercepts, y is zero y = x² - 10x + 24 then x-intercept is (6,0) and (4,0)
For x-intercepts, y is zero y = x² + 10x + 16 then x-intercept is (-2,0) and (-8,0)
For x-intercepts, y is zero y = x² - 25 then x-intercept is (5,0) and (-5,0)
For x-intercepts, y is zero y = x² + 8x + 12 then x-intercept is (-2,0) and (2,0)
What is x-intercepts?X- intercepts is "x coordinates of a point where a line, a curve or surface intersects at x- axis".
According to the question,
a) y = x² - 12x + 32 (Put y=0)
x² - 12x + 32 = 0
(x-8) (x-4) = 0
x - 8 =0: x - 4 = 0
x = 8 and 4
x - intercept is (8,0) and (4,0)
b) y = x² - 10x + 24 (Put y=0)
x² - 10x + 24= 0
(x-6) (x-4) = 0
x - 6 = 0: x - 4 = 0
x = 6 and 4
x - intercept is (6,0) and (4,0)
c) y = x² + 10x + 16 (Put y=0)
x² + 10x + 16 = 0
(x+2) (x+8) = 0
x + 2=0: x + 8 = 0
x = -2 and -8
x - intercept is (-2,0) and (-8,0)
d) y = x² - 25 (Put y=0)
x² - 25 = 0
x² = 25
x = ± 5
x - intercept is (+5,0) and (-5,0)
e) y = x² + 8x + 12 (Put y=0)
x² + 8x + 12 = 0
(x+2) (x+6) = 0

Answer:

Step-by-step explanation:
The grid show the non-possibilities in red, with each number corresponding to the statement that eliminates that choice. The green square (with black text) shows the one combination that is specified already (by statement 4). The lighter green numbers show possible alternatives: first period may be Schiller or English, and room 113 will be the other one. Similarly, Art may be 3rd period or Thomlinson.
__
These choices (light green 5, light green 6) give rise to four possibilities. Working through them, you run into inconsistencies if you choose Schiller for first period. (Art must be, but can't be, in room 112.) That leaves two possibilities.
Again, you run into inconsistencies if you choose Thomlinson as the Art teacher. (The class in 112 is 2 periods after Xavier's class, not 1.)
Hence, the only viable pair of remaining choices is Schiller in room 113 and art in 3rd period.
The final schedule is shown in the attachment.

Additional comment
When I'm working these on paper, I use an X to mark any impossible combinations, and a circle (O) to mark a known combination. In any given 4×4 square of the grid, the remaining cells of the row and column containing a O must be Xs. Consistency must be maintained between rows and columns. This often means filling a circle in one place may result in a circle being filled in another place. Of course, once 3 of the squares in a row or column have Xs, the remaining one must be O.

solve the system of linear equations by substitution. x+4y=18 y=-x+9
Using the substitution method, the solution to the system of linear equations, is: (6, 3).
System of Linear EquationsUsing substitution method, we can make one of the variables the subject of the formula for one of the equations, then find the other variable by substituting.
Given:
x + 4y = 18 --> eqn. 1y = -x+9 --> eqn. 2.Substitute y = -x + 9 into equation 1.
x + 4(-x + 9) = 18
x - 4x + 36 = 18
-3x + 36 = 18
-3x = 18 - 36
-3x = -18
x = 6
Substitute x = 6 into equation 2 to find y
y = -6 + 9
y = 3
Therefore, using the substitution method, the solution to the system of linear equations, is: (6, 3).

enter answers as integers and or as reduced fractions in the form A/B
Answer:
m = -3/4; b = -2
Step-by-step explanation:
y = mx + b
First, we use the coordinates of the points to find the slope, m.
m = (y2 - y1)/(x2 - x1) = (-2 - (-5))/(0 - 4) = (-2 + 5)/(-4) = -3/4
The slope, m = -3/4.
Now we use the slope and the coordinates of one point in the equation y = mx + b to find b.
y = mx + b
y = (-3/4)x + b
Let's use point (0, -2).
-2 = (-3/4)(0) + b
b = -2
Answer: m = -3/4; b = -2

Anas wants to build a one-sample z interval with 85% confidence to estimate what proportion of users will click an advertisement that appears on his website. He takes a random sample of 250 users and finds that 54 of them clicked the advertisement. Answer the following:
1. What critical value z start superscript, times, end superscript should Anas use to construct this confidence interval?
2. Provide the value of margin of error.
3. Provide the confidence interval with 85% of confidence.
4. What would happen if Anas managed to have 500 sample size?
Answer:
See below
Step-by-step explanation:

n(1-p)≥10? √
One-Sample Z-Interval Information
Formula --> [tex]CI=\hat{p}\pm z^*\biggr(\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\biggr)[/tex]Sample Proportion --> [tex]\hat{p}=\frac{54}{250}=0.216[/tex]Critical Value --> [tex]z^*=1.4395[/tex] (for a 85% confidence level)Sample Size --> [tex]n=250[/tex]Margin of Error (MOE) --> [tex]\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}[/tex]Problem 1
As stated previously, Anas should use the critical value [tex]z^*=1.4395[/tex] to construct the 85% confidence interval
Problem 2
Given our formula for the margin of error (MOE), the value is [tex]MOE=\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}=\sqrt{\frac{0.216(1-0.216)}{250}}\approx0.026[/tex]
Problem 3
The 85% confidence interval would be [tex]CI=\hat{p}\pm z^*\biggr(\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\biggr)=CI=0.216\pm 1.4395(0.026)\appro=\{0.1786,0.2534\}[/tex], which means that we are 85% confident that the true proportion of people that clicked on the advertisement is between 0.1786 (~45 people) and 0.2534 (~63 people)
Problem 4
Increasing the sample size to [tex]n=500[/tex] is going to decrease the margin of error because it is a closer representation of the population, but, alas, requires more time, energy, and resources to observe.
