Step-by-step explanation:
a.) the given term can be written as
=
[tex] \sqrt{3} \times \sqrt{3 \times 2} [/tex]
=
[tex] \sqrt{3 \times 3 \times 2} [/tex]
=
[tex]3 \sqrt{2} [/tex]
hence the given term is
[tex]3 \sqrt{2} [/tex]
where b = 3
b.)
=
[tex] \sqrt{8} \times \sqrt{18} [/tex]
=
[tex] \sqrt{2 \times 2 \times 2} \times \sqrt{2 \times 3 \times 3} [/tex]
=
[tex] \sqrt{2 \times 2 \times 2 \times 2 \times 3 \times 3} [/tex]
=
[tex]12[/tex]
hence the given term is 12
For which of these variables would you be interested in finding the biserial correlation coefficient rather than the point-biserial correlation coefficient?
Answer:
The formula for the point biserial correlation coefficient is:
point biserial correlation formula
M1 = mean (for the entire test) of the group that received the positive binary variable (i.e. the “1”).
M0 = mean (for the entire test) of the group that received the negative binary variable (i.e. the “0”).
Sn = standard deviation for the entire test.
p = Proportion of cases in the “0” group.
q = Proportion of cases in the “1” group.
Most people won’t work this formula by hand as most statistical software packages can calculate the coefficient for you.
How does the denominator of the sum, 1 5/12, compare to the denominators of the addends, 2/3 and 3/4?
Answer:
There denominators are same, ie = 12
Step-by-step explanation:
Sum , 1 + 5/12 = (12 + 5) / 12
= 17 / 12
Sum , 2/3 + 3/4 = (8 + 9) / 12
= 17 / 12

find the measure of all of the angles on the diagram
Answer:
Angle 1: 135*
Angle 2: 45*
Angle 3: 45*
Angle 4: 135*
Angle 5: 135*
Angle 6: 45*
Angle 7: 45*
Angle 8: 135*
Step-by-step explanation:
So we have angle 2, 45*, we can subtract 45 from 180 to get the angle for 1. Since everything is the same size as either 1 or 2 we can just plug in the bigger angle number we have for it, ex 4= 135 and so is 7.
If you don't understand something please don't hesitate to ask.
Answer:
Step-by-step explanation:
∠2 = 45
∠3 = ∠2 {Vertically opposite angles}
∠3 = 45
∠7 = ∠3 {Corresponding angles}
∠7 = ∠45
∠6 = ∠7 {Vertically opposite angles}
∠6 = 45
∠1 + ∠2 = 180 {Linear pair}
∠1 + 45 = 180
∠1 = 180 -45
∠1 = 135
∠4 =∠1 {Vertically opposite angles}
∠4 = 135
∠8 = ∠4 {Corresponding angles}
∠8 = 145
∠5 = ∠4 {Alternate interior angles}
∠5 = 145

Answer:
30.96 m^2
Step-by-step explanation:
Side length of the square is also the diameter of the semicircle so:
r = 0.5 * 12 m = 6 m
Since you want the area of the shaded area, you have to subtract the area of both semi circles from the area of the square:
Square Area - Semi Circle Area - Semi Circle Area = Shaded Region Area
(12 m * 12 m) - (0.5 * 3.14 * 6^2 m) - (0.5 * 3.14 * 6^2 m)
= 144 - 56.52 - 56.52
= 30.96 m^2

x=a+b+4 and a is inversely proportional to y²; b is inverseley propotional to 1/y. when y = 2 x = 18 and when y = 1 x = -3. find x when y = 4
Answer:
When y = 4, x is equal to 39
Step-by-step explanation:
The given parameters are;
x = a + b + 4
a ∝ 1/y²
b ∝ 1/(1/y) = y
When y = 2, x = 18
When y = 1, x = -3
Therefore, we have;
a·y² = j
a = j/y²
b ∝ 1/(1/y)
∴ b ∝ y
b = k·y
When y = 2, x = 18, we have;
a = j/y² = j/2² = j/4
b = k·y = k·2
x = a + b + 4
∴ 18 = j/4 + k·2 + 4...(1)
When y = 1, x = -3, we have;
a = j/y² = j/1² = j
b = k·y = k·1 = k
x = a + b + 4
∴ -3 = j + k + 4...(2)
Making 'j', the subject of equation (1) and (2) gives;
From equation (1), we have;
18 = j/4 + k·2 + 4
∴ j = (18 - 4 - k·2) × 4 = 56 - 8·k
From equation (2), we have;
-3 = j + k + 4
∴ j = -3 - 4 - k = -7 - k
Equating the two values of 'j', gives;
56 - 8·k = -7 - k
56 + 7 = 8·k - k
63 = 7·k
k = 63/7 = 9
k = 9
From equation (2), we get;
-3 = j + k + 4
k = 9
∴ -3 = j + 9 + 4
j = -3 - 9 - 4 = -16
j = -16
When y = 4, we get;
x = a + b + 4
a = j/y²
b = k·y
∴ x = j/y² + k·y + 4
Plugging in the values of 'j', and 'k' and y = 4, gives;
x = (-16)/y² + 9·y + 4
∴ x = (-16)/4² + 9 × 4 + 4 = 39
x = 39
Therefore;
When y = 4, x = 39.

Andrew and Sebastian are training for a weightlifting competition. In order to prepare, each of them has created their own personal training plan as follows:
• Andrew will start off by lifting 50 pounds and will increase the weight he lifts by 10% each week.
• Sebastian will start off by lifting 40 pounds and will increase the weight he lifts by 10 pounds each week.
Which of the following statements are true?
OOOOO
Andrew and Sebastian both increase the weight they lift each week by the same amount
Andrew's training plan can be modeled by a linear function, and Sebastian's training plan can be modeled by an exponential function.
Andrew's training plan can be modeled by an exponential function, and Sebastian's training plan can be modeled by a linear function.
Andrew increases the weight he lifts each week by equal factors, and Sebastian increases the weight he lifts each week by equal differences
Andrew increases the weight he lifts each week by equal differences, and Sebastian increases the weight he lifts each week by equal factors

Seven less than a number is 18
Let the number be n.
Now, "seven less than a number" means we subtract 7:-
n-7
This expression is equal to 18:-
[tex]\sf{n-7=18}[/tex]
[tex]\mathcal{SOLUTION:-}[/tex]
Add 7 to both sides:-[tex]\bigstar{\boxed{\pmb{n=25}}}[/tex]

what ratios is equivalent to 6/7
Answer:
6:7
12:14
24:28
Step-by-step explanation:
The beginner ratio is 6:7 to find new equal ratios we just multiply both numbers by a number. In those, each of them is multiplied by two. You can multiply it by any number as long as you keep the 6's answer in the 6's spot and same for 7 & that you multiply both sides and not just one.
