If the mean of A and B is 20 , the mean of B and C and the mean of A,B and C us 18 . What is the mwan of A and C
Answer:
the mean of A and C is 10
Step-by-step explanation:
Given that
The mean of A and B is 20
The mean of B and C is 24
And, the mean of A, B and C is 18
We need to find out the mean of A and C
Since the mean of A and B is 20
So, a + b = 20 × 2
= 40
Likewise for B and C it is 48
And, for A, B and C, it is 54
So,
a + b = 40
b + c = 48
a + b + c = 54
So if we put the value of b + c in the above equation
a + 48 = 54
a = 6
b = 34
c = 14
Now the mean of the A and C is
= (6 + 14) ÷ 2
= 10
Hence, the mean of A and C is 10

Consider a person from birth to age 18 and the height of that person each of the years between birth and age 18. Which best describes the variables of age and height?
no correlation
positive correlation
negative correlation
Answer:
Seems to be no correlation at all.
Answer:
anges between -1 and +1 and quantifies the direction and strength of the linear association between the two variables. The correlation between two variables can be positive (i.e., higher levels of one variable are associated with higher levels of the other) or negative (i.e., higher levels of one variable are associated with lower levels of the other).
The sign of the correlation coefficient indicates the direction of the association. The magnitude of the correlation coefficient indicates the strength of the association.
For example, a correlation of r = 0.9 suggests a strong, positive association between two variables, whereas a correlation of r = -0.2 suggest a weak, negative association. A correlation close to zero suggests no linear association between two continuous variables.
It is important to note that there may be a non-linear association between two continuous variables, but computation of a correlation coefficient does not detect this. Therefore, it is always important to evaluate the data carefully before computing a correlation coefficient. Graphical displays are particularly useful to explore associations between variables.
The figure below shows four hypothetical scenarios in which one continuous variable is plotted along the X-axis and the other along the Y-axis.
Step-by-step explanation:

Answer:
The surface area of the shape is 292 in^2
Step-by-step explanation:
Here, we want to find the surface area of the cuboidal shape
Mathematically, the area of a cuboid can be calculated using the formula;
A = 2(lb + lh + bh)
where l is the length which is 7 inches
b is the breadth which is 6 cm
h is the height which is 8 cm
Substituting these values, we have
A = 2((8 * 6) + (7 * 6) + (8 * 7))
A = 2(56 + 42 + 48)
A = 2 * 146
A = 292 in^2

Write the equation of the line in Slope-Intercept form.
Answer:
Y=-2/3+4
Step-by-step explanation:
The slope of the equation can be solved with
2-4/3-0 y2-y1 divide by x2-x1 which gives 3/2 and the y intercept the point at which the slope hits the y intercept which is 4. Also the slope is negative as it’s pointed downwards.
Getting the slope:
m=[tex](y_1 - y_2 )/(x_1 - x_2)[/tex]
Using this formula, the slope is calculated to be -2/3
To find intercept, plug in a point value into equation and solve.
Intercept = 4
Total equation: y=-2/3x + 4

Find the area of the regular polygon with the given radius or apothem.Shape is a hexagon with 4cm inside
Answer:
55.43cm^2
Step-by-step explanation:
Area of a hexagon given the apothem = 1/2 x perimeter x apothem
apothem = 4cm
To find the perimeter, take the following steps
4 = x√3
x = 4/√3
Multiply by 2
8√3
Since a hexagon has 6 equal sides, multiply by 6
Perimeter = 48√3
Area = (1/2) x 48√3 x 4 = 55.43cm^2
Marcy mailed a package weighing1.337 kilograms. How does the value represented by the 3 in the tenths place compare with the value represented by the 3 in the hundredths place?
If a number has a decimal point , then the first digit to the right of the decimal point indicates the number of tenths. The second digit to the right of the decimal point indicates the number of hundredths.
In this case the .3 indicates 3/10ths of a kilogram. or 300 grams!
In the other case 0.03 indicates 3/100ths of a kilogram or 30 grams!
So, to compare the two:
the tenths decimal is 10 times bigger than the decimal in the next spot (hundredths)

What two numbers multiply to +34 and add to -19
Answer:
17 * 2 = 34
-10 + (-9) = -19 or -29 + 10 = -19
Step-by-step explanation:
For the first question, divide 34 * 2 and you get 17, DOUBLE CHECK YOUR ANSWER!
17*2 = 34 ✔
For the second, mess around with a few numbers add +10 and -29, COUNT DOWN from 10 and -29.
since + + + = + then - + - = -
if 10+9=19 then do the same with -
-10 + (-9) =-19

The probability of getting a blue marble is 0.15.
What is probability?The probability of an event is a number that indicates how likely the event is to occur.
Given that, a bag contains marbles of four different colors: 8 blue marbles, 24 red marbles, 16 green marbles and 4 yellow marbles,
We need to find the probability of picking a blue marble at random out of the bag,
Probability(Event) = Favorable Outcomes / Total Outcomes
Favorable Outcomes = 8
Total Outcomes = 52
Therefore,
P(blue marble) = 8/52 = 0.15
Hence, the probability of getting a blue marble is 0.15.
