Histogram attached
Answer and explanation:
To find the center of the distribution, we find the mean of the distribution.
Mean= sum of all values/number of values
To calculate the mean of the distribution using the histogram(attached) with given frequencies, we find the mid point of each class and multiply by its frequency to get the sum of the values(estimated) and then divide by the number of values(sum of the frequencies of the classes)
midpoint of 50-60=50+60/2=55
midpoint of 70-80=150/2= 75
midpoint of 80-90=170/2=85
midpoint of 90-100=190/2=95
midpoint of 100-110=210/2=105
Midpoint of 110-120=230/2=115
Midpoint of 120-130=250/2=125
Midpoint of 130-140=270/2=135
Midpoint of 140-150=290/2=145
Midpoint of 150-160=310/2=155
Sum of the values= 55*frequency= 55*3+75* 2+85*1+95*7+105*17+115*29+125*10+
135*2+145*3+155*3
Sum of all values =8605
Number of values= 3+2+1+7+17+29+10+2+3+3=77
Mean= 8605/77= 111.753
Therefore the center of the distribution is between 110 and 120 calories.

Which expression is equivalent to 6x2 – 19x – 55?
Answer: (x - 5)(6x + 11)
Step-by-step explanation:
Let's factorie the given expression using middle term splitting method.
Thus, we have ;
=> 6x² - 19x - 55
=> 6x² - 30x + 11x - 55
=> 6x(x - 5) + 11(x - 5)
=> (x - 5)(6x + 11)
Hence,
The equivalent expression of 6x² - 19x - 55 is :
(x - 5)(6x + 11).
The points (20, 80) and (30, 120) form a proportional relationship. What is the slope of the line that passes through these points?

If a figure starts off in a Quadrant I and is reflected along the x-axis and then rotated 180 degrees about the origin, what quadrant will it land on?
Answer:
Quadrant 2
Step-by-step explanation:
First you reflect and it goes to Quadrant 4(Positive,Negative). When rotating 90 degrees you go to the next quadrant. In this case it is 180 degrees, so it ends up two quadrants away. The final location is quadrant 2

What is the graph?A graph, which is a mathematical representation of a network, describes the relationship between lines and points. A graph is made up of a few points and the arcs that connect them. Neither the location of the points nor the length of the lines matters.
Given that, the equation of a line is y=x+2.
Substitute x=0, 1, 2, 3, 4, 5 and 6 in the equation y=x+2, we get
y = 2, 3, 4, 5, 6, and so on.
So, the coordinate points are (0, 2), (1, 3), (2, 4), (3, 5) and (4, 6).
In the obtained graph, we got the points (0, 2), (1, 3) and (2, 4), they are accurate as we calculated.
Yes, the ordered pairs are accurate as estimated by our theoretical calculations.

Shawn uses 45N of force to stop the cart 1 meter from running his foot over. How much work does he do?
Answer:
[tex]\boxed {\boxed {\sf 45 \ Joules}}[/tex]
Step-by-step explanation:
Work can be found by multiplying the force by the distance traveled in the direction of the force.
[tex]W=F*d[/tex]
The force is 45 Newtons.
The distance traveled is 1 meter.
[tex]F=45 \ N \\d= 1 \ m[/tex]
Substitute the values into the formula.
[tex]W=45 \ N * 1 \ m[/tex]
Multiply.
[tex]W=45 \ N*m[/tex]
1 Newton meter is equal to 1 Joules.
Therefore our answer of 45 Newton meters is equal to 45 Joules.
[tex]W= 45 \ J[/tex]
The work done is 45 Joules.
Step-by-step explanation:
[tex]\sf Required\:Answer\begin{cases} \sf Force_(f)=45N \\ \sf Distance_(d)=1m \\ \sf As\:we\:know\:that \\ {\boxed{\sf Work_(w)=Force_(f)\times Distance_(d)}} \\ \sf W=45 \times 1Nm \\ \sf =45Nm \\ \longrightarrow {\underline{\boxed{\bf W=45Joule}}}\end {array}[/tex]

In the question the value of IQ is missing that is = 140
Given value:
IQ= 140
MA=35
CA=?
Formula for calculating the chronological age:
[tex]\to CA = (\frac{MA}{IQ})\times 100[/tex]

Answer:
Multiply the first, outside, inside, and last terms of the binomials.
Multiply a times a, a times -b, b times a, and b times -b.
This is the same as just squaring a and squaring b.
A shortcut is to add a squared and b squared

Callan goes for a hike every Saturday. Callan hikes at a rate of 3 miles per hour.
Complete the table for the given ratio.
Answer:
(1) 27 meters. (2, 3) Both distances in miles (y) are 10 miles (y)
Step-by-step explanation:
For the first question, every mark represents 9 meters. and 9 multiplied by 3 is 27.For the second half, look at the y section and see that the dots are a line higher than 9. So they both have 10 as y.
Find BA
CB + BA = CA
7x-2 + 5x+1 = 23
Answer:
BA = 11
Step-by-step explanation:
CB + BA = CA , substitute values
7x - 2 + 5x + 1 = 23, that is
12x - 1 = 23 ( add 1 to both sides )
12x = 24 ( divide both sides by 12 )
x = 2
Thus
BA = 5x + 1 = 5(2) + 1 = 10 + 1 = 11

athickness of 7 * 10^-2 mm, what will the
total thickness of the paper and the
construction
board be? Write your ansicer
in scientific notation
Answer:
9.5 * 10^-2 mm
Step-by-step explanation:
To find the total thickness, we proceed to add the two thickness that we have
Mathematically, this will be;
0.025 mm + 7 * 10^-2 mm
7 * 10^-2 mm = 0.07
So we have;
0.025 mm + 0.07 mm = 0.095
In scientific notation, this is 9.5 * 10^-2 mm
1) The sum of two consecutive integers is greater than 21. Find the smallest possible values for the integers.
The smallest possible values for the integers will be 11 and 12.
What exactly is simplification?Simplifying means making something easier to do or comprehend, as well as making something less difficult.
Let the two consecutive integers will be x and y.
From the given conditions the sum of two consecutive integers is greater than 21;
x+y>21
11 and 12 are the only two consecutive digits has the sum of 21.
