The total number of pounds of cheese Kala bought is 1.75.
What is the Bar diagram?Bar graph (bar chart) is a graph that represents the categorical data using rectangular bars.
The bar graph shows the comparison between discrete categories.
Given
Kala bought two types of cheese at a deli.
She bought 0.50 pound of American cheese and 1.25 pounds of Swiss cheese.
The bar diagram and equation below represent Kala’s purchase, where p represents the total number of pounds of cheese she bought.
A bar diagram. The top bar contains p.
The bottom bars contain 0.50 and 1.25.
p = 0.50 + 1.25
The total number of pounds of cheese Kala bought is;
= 0.50 + 1.25
= 1.75
Hence, the total number of pounds of cheese Kala bought is 1.75.

A father is now 38 years older than his son.Ten years ago he was twice as old as his son.How old are the father and son?
Answer:
father's age = 86
son's age = 48
Step-by-step explanation:
86-10=76
48-10=38
38*2 = 76
Answer:
father: 86son: 48Step-by-step explanation:
You can use your number sense to reason your way through this problem, or you can write equations for it. If the father is 38 years older than his son, and that makes him twice as old, the son must be 38 and the father 76. This was the condition 10 years ago, so their ages now are ...
father: 86son: 48__
If you prefer to solve a set of equations, you can assign variables f, s, to the father's age and the son's age respectively.
f = s +38 . . . . . . the father is 38 years older than the son.
(f -10) = 2(s -10) . . . . 10 years ago, the father was twice as old as the son
The first equation gives an expression we can use to substitute into the second equation:
s +38 -10 = 2s -20 . . . . substitute for f, eliminate parentheses
48 = s . . . . . . . . . . . add 20-s, collect terms
f = 48 +38 = 86
The father is 86; the son is 48.
_____
Additional comment
An age difference remains the same through the years. It is the same now as 10 years ago or 10 years in the future. A multiplying factor for ages gets smaller as years go by. Someone 3 times as old now will only be 2 times as old at some point in the future, for example.
The difference in ages is a multiple of the younger age that is 1 less than their ratio. In other words, if A is 3 times as old as B, the difference (A-B) is exactly (3 -1)×B = 2B. In the above problem, this was (f-s)=38; f/s=2, so we know 38 = (2 -1)s = s.
2. Is (-3, -9) a solution of the equation y 3x?
Answer:
if you mean y=3x, then yes
Step-by-step explanation:
solution:
substitute s by -3, we obtain
y= 3 (-3)
y= -9
So, if x= - 3 then it's y= - 9

Which choice best describes the slope of the line that passes through (0, 0) and (5, 0)? A. B. 0 C. D.
Hey there!
Use the slope formula:
[tex]\bold{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]
[tex]\bold{\displaystyle\frac{0-0}{5-0} }[/tex]
[tex]\bold{\displaystyle\frac{0}{5} }[/tex]
[tex]\bold{0}[/tex]
There's an easier way to determine the slope.
As you can see, the y-coordinates of the points that the line passes through (0, 0) --> the origin and (5, 0).
This means the slope's 0.
Remember that
if the points that a line passes through have the same y-coordinates, then the slope of the line is 0.Hence, the slope's 0.
Hope everything is clear.

Two groups of students were asked how far they lived from their school. The table below shows the distances in miles:
Group A (distance in miles) 1 1.5 8 9.2 6.8 4.5 4.8 2.5 0.76
Group B (distance in miles) 2 2.5 3.23 1.3 1.8 2.4 3 1.5 1.8
Which statement best compares the mean distances for the two groups?
It is equal for Group A and Group B.
It is greater for Group B than Group A.
The value for group A is double the value for Group B.
The value for group B is three times the value for Group A.
Answer:
C. The value for Group A is double the value for Group B
Step-by-step explanation:
First, you add all the numbers from each group.
A: The distance in total is 39.06
B: The distance in total is 19.53
To find the mean, which is another way of saying the average, you divide the sum with how many numbers there are. (hope this makes sense, I suck at wording)
A: There are 9 numbers in total, hence, 39.06/9 = 4.34
B: There are 9 numbers in total, hence, 19.53/9 = 2.17
Those are the mean distance for the two groups.
2.17 * 2 = 4.34
Hence, C (third statement)
Answer:
C. Its value for Group A is double the value for Group B.

Step One, Find out the radius of the inner circle:
Circumference = 2πr
Circumference = 12.56
12.56 = 2πr
12.56/3.14 = 2r
4 = 2r
r = 2m
Step Two, Find out the radius of the entire circle:
2m + 3m = 5 m
Step Three, Find out the radius:
Area of circle = πr^2
Area of circle = 3.14 * 5^2
Area of circle = 3.14 * 25
Area of circle = 78.5 square meters

Identify the type of bias involved in this sampling design: A coffee company in Cincinnati wants to know what percent of local households drink coffee at least twice a week. A company representative calls 400 randomly-selected households during the daytime and finds that 50% of those who responded drink coffee at least twice a week. Wording of question bias Non-response bias Response bias Undercoverage
Answer:
Undercoverage Bias
Step-by-step explanation:
Undercoverage Bias occurs when some members of the population under study that should be included in the study are omitted. This then means that the sample is not a true representation of the entire population. In the sampling design above, a problem that would most likely occur would be undercoverage bias.
This is because the sample that was chosen for the study did not represent the entire population of the local households. Since they came during the daytime to conduct their poll, they have omitted members of the population who go to work and may not be at home at the time of the poll.

PLEASE SHOW STEP-BY-STEP
Answer:
a2−b2=(a−b)(a+b).
Since a≥0 and b>0, a+b>0 and a−b<0 since a<b, thus: (a−b)(a+b)<0. So a2−b2<0. Thus a2<b2.

6 = 2(y+2)
What does y equal?
Answer:
y = 1
Step-by-step explanation:
[tex]\frac{6}{2}=\frac{2(y+2)}{2}\\ \Leftrightarrow 3-2=y=2-2\\\Leftrightarrow y=1[/tex]
The solution to the given equation 6 = 2(y+2) is y = 1, which is determined by distribution and arithmetic operations.
The equation is given as follows:
6 = 2(y+2)
To solve the equation 6 = 2(y + 2) for y, we need to isolate y on one side of the equation.
First, distribute the 2 on the left side by multiplying it with y and 2:
6 = 2y + 4.
Next, move the constant term (4) to the other side of the equation by subtracting it from both sides:
6 - 4 = 2y
2 = 2y
y = 2/2
Apply division operation to get:
y = 1
Therefore, the solution to the given equation is y = 1.
