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.

X+123°=180°(BEING DUM OF CO INTEROIOR ANGLES IS EQUAL TO 180°)
X=180°-123°
X=57°
Hi!
x = 57 degrees.
Explanation:
There is a straight line, so that must mean there is a linear pair. We know the first part of that pair is 123 degrees. The linear pair adds up to 180 degrees. Subtract 123 from 180 to get 57.
That angle and x are alternate interior angles, so they are equivalent.
a plane ticket to Barcelona costs £175
Answers
Answer:
Given:
A plane ticket to Barcelona costs £175 the price decreases by 6%
To find:
The new price of the plane ticket
Solution:
The ticket to Barcelona costs £ 175
The price decreases by 6%
⇒ 6% = 6/100 = 3/50
The new price of the plane ticket is decreased by the amount,
= £ 175 × 3/50
= £ 10.5
Therefore, the new price of the plane ticket is given by,
= £ 175 - £ 10.5
= £ 164.5

Answers
10% of 40 is 4
40-4=36
8.25% of 36 is 2.97
36+2.97= 38.97
Answer:
$38.97
Step-by-step explanation:
100% - 10% = 90% = 0.9
$40 × 0.9 = $36
100% + 8.25% = 108.25% = 1.0825
$36 × 1.0825 = $38.97

If they instead chose front and back covers of thickness 1/3 of an inch, how would this change the equations in the previous two parts
Answers
Answer:
where is the rest of the question
Step-by-step explanation:
Answer:
y = 1/2 + 1/4*x
Explanation:
Given that the front cover has a thickness of 1/4 an inch and back cover also has a thickness of 1/4 an inch, then, the addition of both gives to the book thickness of 1/4 + 1/4 = 1/2 inch, despite how many pages it has.
Given that for every hundred pages a thickness of 1/4 inch is added to the book, then the equation is:
y = 1/2 + 1/4*x
where y refers to the width of the book, and x refers to every hundred pages printed on bond paper. Y is measured in inches.

Megan bought 2 1/4 pounds of bananas for 0.80 per pound and 1 1/2 pounds of strawberries for 1.10 per pound how much more did Megan spend on bananas than on strawberries
Answers
Answer:Megan spent 0.15 pounds more on bananas than strawberries
Step-by-step explanation:
Step 1
Cost of bananas = 2 1/4 pounds of bananas for 0.80 per pound
2 1/4 x 0.80 = 1.8 pounds
Cost of strawberry= 1 1/2 pounds of strawberries for 1.10 per pounds
1 1/2 x 1.10 = 1.65.
Step 2 how much more means the difference between the cost of bananas and strawberry .
Therefore, we have Cost of bananas - cost of strawberries
1.80 pounds - 1.65 pounds=0.15
Megan spent 0.15 pounds more on bananas than strawberries
Help plz mportant!!! Choose the point-slope form of the equation below that represents the line that passes through the point (-1.6) and has a slope of -3.
а. y - 6 = -3x - 3
b. y - 6 = -3(x + 1)
c. y=-3x + 3
d. 3x+y=3
Answers
Answer:
B
Step-by-step explanation:
point slope uses the form y - y1 = m(x - x1)
m stand for slope. in this case it is -3
x1 is -1 and y1 is 6
when you plug it in, you get
y - 6 = -3(x - [-1])
which simplifies to your final answer: y - 6 = -3(x + 1)

Answers
Answer:
The y intercept is 4
Step-by-step explanation:
Given:
-Given point: (-5,-6)
-Slope of 2
1) Put the equation into point-slope form y - y1 = m(x - x1)
With the given, we can plug it all in using this formula!
-y1 = -6
-x1 = -5
m = 2
(you would change these negative numbers into positives because the equation shows them being subtracted! remember that two negatives make one positive!)
y+6= 2(x+5)
2) Simplify
y+6= 2(x+5)
y+6=2x+10
y=2x+4
With y=2x+4, set x to 0 because the y intercept is where x is equal to 0 and you get 4!

while(condition):
Comparing while(condition): to while(x < 26),
we'll see that while(x < 26) has a missing colon.
So, the error in the program is a missing colon and the solution is (option a) adding a colon to the end of the while statement
