Answer:
x = 1&16
Step-by-step explanation:
f(x) = 0 then
0 =x^2 - 17x + 16
(x-1)(x-16) =0
x -1 =0 or x-16=0
x =1 & x = 16
Answer:
x = 5, x = 12.
Step-by-step explanation:
This is a quadratic function which may factor to the form (x - a)(x - b) whose zeroes are a and b.
To factor this we need two numbers whose product is +60 and whose sum is -17. They are -5 and -12 ( -5*-12 = 60 and -12 + -5 = -17).
So the factors are :
(x - 5)(x - 17)
To find the zeros we equate this to 0:
(x - 5)(x - 17) = 0
x- 5 = 0 gives x = 5
and
x - 12 = 0 gives x = 12.

The box and whisker plots represent the number of minutes spent by users on two different social media groups. Which THREE statements are correct when comparing the plots?
A) The median time for users of Group B is 40 minutes.
B) Group B has greater median value than Group A.
C) The data for Group B varies slightly more than Group A.
D) The spread of the data for Group A is 25 minutes.
E) The spread of the data for Group A is 40 minutes.
Answer: I feel the answer is C
Step-by-step explanation:
The three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.
What is a box and Whisker plot?A box and whisker plot displays the minimum value, lower quartile (Q1), median, upper quartile (Q3), and maximum values of a data set.
Let's analyze each of the given statements given the box and whisker plots for both groups:
Statement A is TRUE:
Median time for Group B = 40.
Statement B is FALSE:
Median value for Group A is between 45 and 50
Median value for Group A is 40.
Therefore, Group B does NOT have median value greater than Group A.
Statement C is TRUE:
The interquartile range (IQR) for Group A and Group are similar, therefore, data for Group B varies slightly more than Group A.
Statement D is TRUE while E is FALSE:
Spread for Group A (IQR) = 55 - 30 = 25 minutes
Therefore, the three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.

Solve the equation. x6−9=7 x = ___ (type only an integer - no words, variables, or equal signs)
Answer:
We want to solve the equation:
x*6 - 9 = 7
To solve this we need to isolate x in one side of the equation.
First, we need to add 9 in both sides of the equation to get:
(x*6 - 9) + 9 = 7 + 9
x*6 - 9 + 9 = 16
x*6 = 16
Now we can divide both sides by 6, to get:
x*6/6 = 16/6
x = 16/6 = 2.66
This is not an integer as the question wants, so i only can suppose that the question is incorrectly written.
If the equation was something like:
x/6 - 9 = 7
Using the same approach than before (the only difference is that we multiply both sides by 6 in the second step), we would get:
x/6 = 7 + 9 = 16
x/6 = 16
x = 16*6 = 96
x = 96
Which is an integer, so i suppose that the actual equation is "x/6 - 9 = 7" instead of "x*6 - 9 = 7"

Answer:
72 meters
Step-by-step explanation:
12 times 9 is 72
Answer:
243 m²
Step-by-step explanation:
Given the scale is 4 : 6 = 2 : 3 , then
scale of areas = 2² : 3² = 4 : 9
area of scale drawing = 12 × 9 = 108 cm²
let x be the actual area then using proportion
[tex]\frac{4}{108}[/tex] = [tex]\frac{9}{x}[/tex] ( cross- multiply )
4x = 972 ( divide both sides by 4 )
x = 243
Actual area = 243 m²

Konni and her son, Declan, went for a run. Declan ran for a total of 27 minutes and 45 seconds. Konni ran for twice as long as Declan. How much time did Konni spend running?
Answer:
Konni spent 55 minutes and 30 seconds running.
Step-by-step explanation:
27 x 2 = 54
30 x 45 = 90
90/60 = 1.5
1.5 minutes is one minute and 30 seconds.

In ijk,i=170 inches,j=119 and k=42.find the area of ijk,to the nearest square inch
9514 1404 393
Answer:
25,975 in²
Step-by-step explanation:
Since your j+k < i, we assume that not all of these dimensions are side lengths. If we assume ...
i = 170 in
J = 119°
K = 42°
Then we can find side j using the law of sines.
I = 180° -119° -42° = 19°
Then the law of sines tells us ...
j/sin(J) = i/sin(I)
j = i·sin(J)/sin(I) = (170 in)sin(119°)/sin(19°) = 456.695
Then the area of the triangle is ...
A = (1/2)(i·j·sin(K)) = (1/2)(170 in)(456.695 in)sin(42°) ≈ 25,975.03 in²
The area of triangle IJK is about 25,975 square inches.

The perimeter of a worksheet is 28 inches. The worksheet is 6 inches tall. How long is it?
Answer:
The worksheet is 8 inches long
Step-by-step explanation:
Here, we want to get the length of the worksheet
From the description, we can see that the worksheet is rectangular in shape
Thus;
P = 2(l + b)
28 = 2(l + 6)
28/2 = l + 6
14 = l + 6
l = 14-6
l = 8 inches

Hii! I need help with this question! The question is "You have 8 hours to get ready and 5 1/2 of those hours have already passed. How much time do you have left?" Someone help ASAP!
Answer:
2 1/2 hours
Step-by-step explanation:
Answer:
3 1/2 hours left
Step-by-step explanation:
Write an equation for this:
8 - 5 1/2 = how much time you have left
(8 is the total hours, you subtract since the hours passed, and 5 1/2 is the amount of hours passed)
Solve equation:
8 - 5 = 3, add the 1/2
So, 8 - 5 1/2 = 3 1/2 or 3.5

Jana, a high school principal, hosted a movie event at her school. Jana's assistant kept track of the number of students in each grade who attended the event. The distribution shown in the table
represents the number of students in each grade that were present.
Grade Level
Sophomore-56
Senior-70
Freshman-52
Junior-60
Jana knows that the grade levels are equally distributed across the school of 1,200 students. She would like to use a chi-square test to see if the proportion of individuals in each class at the
movie are also equally distributed. How many seniors would be expected at the event?
Answer:
59.5 Seniors expected
Step-by-step explanation:
"Equally distributed" means that it is expected that each grade has equal number of students for 1200 schools. This means 1200/4 = 300 students expected in each grade for 1200 students. The proportion would be 300/1200 = .25
The actual total of the school shown is (56+70+52+60) = 238
Therefore 238 * .25 = 59.5 expected students in each grade for this school
The proportion for each grade can also be found by just knowing that each grade has the same proportion.There are 4 grades so 1/4 = .25
