-1/3 (n + 15) = -2
46 = -6t -8
Urgent. Please answer ASAP. Thanks guys!
Answer:
n= -9, t= -9
Step-by-step explanation:
1) -1/3(n+15)=-2
-1/3×n+-1/3×15=-2
-1/3×n -5= -2
-1/3 n-5+5= -2+5
-1/3×n=3
3/-1×-1/3×n=3/-1×3
n= -9
2) 46 = -6t -8
−6t−8=46
−6t−8+8=46+8
−6t=54
Divide both sides by -6
t=-9

Question 10(Multiple Choice Worth 1 points)
(05.02 MC)
The table below shows data from a survey about the amount of time students spend doing homework each week. The students were in either college or high school:
High Low Q1 Q3 IQR Median Mean σ
College 50 6 8.5 17 8.5 12 15.4 11.7
High School 28 3 4.5 15 10.5 11 10.5 5.8
Which of the choices below best describes how to measure the spread of these data?
(Hint: Use the minimum and maximum values to check for outliers.)
Both spreads are best described by the IQR.
Both spreads are best described by the standard deviation.
The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Answer:
The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
Step-by-step explanation:
The college data has large outliers which skews the data, therefore the IQR is better measure of spread.
The high school data does not appear to be skewed so the standard deviation is fine as a measure of spread.

The distribution of 4 in the following expression (5+s)4
Answer:
( 5 + s ) 4 = 20 + 4 s
Step-by-step explanation:
Distribution property
Let a, b and c are numbers then distribution property is defined by
a( b + c) = a b + a c
(a+ b) c = a c + b c
Given that
( 5 + s ) 4 = 5× 4 + s× 4
= 20 + 4 s
Final answer:-
( 5 + s ) 4 = 20 + 4 s
Sum of two numbers = 15 (Addition)
Difference of two numbers =3 (Subtraction)
Find the two numbers.
What is the product of those two numbers? (Multiplication)
Answer:
The numbers are x= 9 and y =6
The product of two numbers
x y = 9 × 6 = 54
Step-by-step explanation:
Step(i):-
Let x and y are two numbers
Given that the sum of two numbers
x + y = 15 ..(i)
Given that the difference of two numbers
x - y = 3 ..(ii)
adding (i) and (ii) , we get
x + y + x -y = 15 +3
2 x = 18
x =9
Step(ii):-
Substitute x = 9 in equation (i) , we get
x + y = 15
9 + y = 15
y = 15 - 9
y = 6
Final answer:-
The numbers are x= 9 and y =6
The product of two numbers
x y = 9 × 6 = 54

Steve prepreformed the chemistry experiment in which divided 5/8 of a box of baking soda evenly among the five bottles he then added vinegar and water teach volatile to make them bubble up like volcanoes how much baking soda do you put in each bottle
Answer:
[tex]\mathbf{ \dfrac{1}{8} \ box}[/tex]
Step-by-step explanation:
Given that:
Steve divided 5/8 of a box evenly among 5 bottles. To determine the amount of baking soda added;
Then, mathematically:
[tex]=\dfrac{5}{8} \ box \div 5[/tex]
[tex]= \dfrac{5}{8} \ box \times \dfrac{1}{5}[/tex]
[tex]\mathbf{= \dfrac{1}{8} \ box}[/tex]
Ryan had some candy to give to his five children. He took three pieces for himself and then evenly divided the rest among his children. Each child received two pieces. With how many did he start?
Answer:
he had 13 peices of candy
Step-by-step explanation:
if he has 3 pieces for himself and 2 for each kid and he has 5 kids then you would just multiply 2 and 5 then add 3
the equation is (2 times 5)+3
The scatterplot for number of enrollments, N, in a sports club, t years after the
year 2006. The equation of the line of the best fit is N = 62t + 35. Find the residual
for the number of enrollments in year 2020 if the actual enrollment is 885
students.
Answer:
13.7 years
Step-by-step explanation:
The equation of the line of the best fit is N = 62t + 35
where
N is the number of enrollments
t is years after the year 2006
If the actual enrollment is 885 students. Put N = 885 in the given equation.
885 = 62t + 35
or
885 -35 = 62t
850 = 62t
t = 13.7 years
So, the required answer is 13.7 years.

Answer:
A.) 3/4
Step-by-step explanation:
You can find this by dividing the distance from point Z to point Y by the distance of point X to point Y. The distance from Z to Y is 6 and the distance from X to Y is 8, so that means that the slope is 6/8, which simplifies to 3/4.

Caleigh had a jewelry box with a volume of 14 cubic inches. The area of the base is 7 square inches. What is the height of caleigh’s jewelry box
Answer:
2 in
Step-by-step explanation:
Given data
Area= 7 in^2
Volume= 14 in^3
from
Volume= Area* height
substitute
14= 7*x
divide both sides by 7
x=14/7
x= 2 in
Hence the height is 2 in

ACFG is a parallelogram, If AG = 2x + 10 and CF = 5x – 2, find CF.
Answer:
d. 18
Step-by-step explanation:
Lengths AG and CF of the parallelogram are equal.
i.e AG = CF
where AG = 2x + 10
CF = 5x -2
→ 2x + 10 = 5x-2
(collecting like terms): 5x - 2x = 10 + 2
→ 3x = 12
x=12÷3 = 4
∴ CF = 5x -2 = 5(4) -2 = 20 - 2 = 18
∴ CF = 18 (answer)

help me please !
Step-by-step explanation:
When you multiply exponents of the same base (variable), add the exponents.
1. The exponents are 12 - 4 + 6 = 14 or c^14
When you divide exponents of the same base, subtract them.
2. 8 - 2 = 6 or c^6
When you raise a power to a power, you multiply the exponents.
3. 4 * 5 = 20 or c^20
When a number is raised to a negative exponent it can be re written like this x^-n = 1/x^n.
4. x^-2 * y / x^4 * y^-1; using the above information, rewrite everything to have positive exponents. If the negative exponent is in the denominator, then it becomes x^n/1
y * y / x^2 * x^4 ; then just add your exponents to simplify
y^2 / x^6
As we said before, a power raised to a power is exponent x exponent.
5. (a^2 * b) ^-1 / (a^-3 * b^2)^-1 ; as before a power raised to a power, multiply the powers.
a^-2 * b-1 / a^3 * b^-2 rewrite this as before, inverting negative exponents. a^3 / a^2 * b^1 * b^2 = a^3 / a^2 * b^3
Simolifynthe new expression to reduce the a variable by subtracting the bottom a^2 from the top a^3 and are left with
a / b^3
Work number 6 like 5, no negative exponents, so there won't be any inversions. Just multiply the outside power times every exponent, then do the division by subtracting exponents of like bases.
When figuring out the problems with constants, treat them like the variables. In number 7 the 5a^2 when raised to the 2nd power would be 5^2*(a^2)^2 = 25 a^4
Im sorry, out of time.
