what times 3 equals 3/10
Answer:
1/10
Step-by-step explanation:
Divide 3/10 by 3. Remember to "keep, flip, change".
3/10 ÷ 3/1
3/10 × 1/3
Multiply across: 3/10 × 1/3 = 3/30
Simplify: 3/30 = 1/10

The table shows the balance of a money market account over time. Write a function that represents the balance in y (dollars) after t years
Answer: y = 200·1.15^t
Step-by-step explanation:
The ratio from one year to the next is 1.15, so the balance is a geometric sequence. Since t starts at zero, we can write the balance (y) after t years as
y = initial value · (common ratio)^t
y = 200·1.15^t
circle WX = xy 2x+16, xw 7x-29 find wx
The value of WX will be; (8y³)/(7y+8).
To find the length of WX, we need to substitute the given values of x and simplify the expression:
WX = xy/(2x+16) - xw/(7x-29)
xy/(2x+16) = xw/(7x-29)
Cross-multiplying, we get:
xy(7x-29) = xw(2x+16)
Expanding both sides;
7x²y - 29xy = 2x²w + 16xw
Rearranging terms and factoring out x;
x(7xy - 2xw) = 29xy - 16xw
Solving for x, we get:
x = (29xy - 16xw)/(7xy - 2xw)
Now we can substitute this value of x into the expression for WX to find its value. use the expression WX = xy/(2x+16):
WX = xy/(2x+16)
WX = y(29xy - 16xw)/[2(7xy - 2xw) + 16]
Simplifying the denominator,
WX = y(29xy - 16xw)/[14xy - 4xw + 16]
Finally, we can substitute the given values of xw and xy to get,
WX = y(29xy - 16xw)/[14xy - 4xw + 16] = (8y³)/(7y+8)
Therefore, WX = (8y³)/(7y+8).

what is x ? full explanation please
Answer:
x = 6
Step-by-step explanation:
Looking at the figure, we can say that it is a vertical angle.
5x - 7 = 23
5x - 7 + 7 = 23 + 7
5x = 30
5x / 5 = 30 / 5
x = 6
Since it is a vertical angle, the other side should be 23⁰. You can also plug in the x value to find if it gives you 23⁰ or not.
5x - 7
5(6) - 7
30 - 7
23
Therefore, x = 6. Hope this helps and stay safe, happy, and healthy, thank you :) !!

What are the zeros of the function f, where f(x) = 6x2 - 9x – 6?
Answer:
Step-by-step explanation:
Use the Pythagorean Theorem to find the zeros of 6x² - 9x - 6.
x = [9±√(9²-4(6)(-6))]/[2(6)] = [9±√225]/12 = [9±15]/12 = 2, -½

How many tiles with dimensions 14 cm and 9 cm will be needed to fit in a rectangular
region whose length and breadth are 168 cm and 72 cm respectively?
Answer:
96 tiles
Step-by-step explanation:
if the rectangular region has dimensions of 168cm by 72 cm then what you would do is multiple them to find the area (168 x 72) which would equal 12,096. then after that you would find the area of the tiles, with the given dimensions being 14cm by 9cm you would do 14 x 9, which would give you 126 sq cm. then after you have you two products, you would then divide them (12,096/126). this equation would give you the sum of 96 tiles be able to fit within the rectangular region.

An occupational safety officer for a large company is conducting a study to investigate back problems in office workers who use a computer for most of the workday. The study will investigate the difference in back problems for workers who stand and workers who sit. A group of 68 volunteers have agreed to participate in the nine-month study. Half the group is randomly assigned to work while standing, and the other half is assigned to work while sitting. At the end of the study, the mean number of back problems between the two groups will be calculated. The officer will use the results to estimate the difference in the mean number of back problems between those who work while standing and those who work while sitting.
Which of the following is an appropriate inference procedure for the study?
A. A one-sample tt-interval for a population mean
B. A one-sample tt-interval for a sample mean
C. A matched pairs tt-interval for a mean difference
D. A two-sample tt-interval for a difference between sample means
E. A two-sample tt-interval for a difference between population means
Answer:
C. A matched pairs tt-interval for a mean difference
Step-by-step explanation:
When the observations from two samples are paired either naturally or by design we find the difference between the two observations of each pair. Treating the differences as a random sample from a normal population with mean ud= u1-u2 and unknown standard deviation , we perform one sample t- test on them . This is called paired difference or a paired or a matched t- test.
The test statistic
t= d`/sd/√n
where d`= ∑ di/n
and sd= ∑ (di- d`)²/n-1
with υ= n-1 degrees of freedom.
For example suppose 10 young recruits are given a strenuous physical training programme by Army. Their weights are recorded before they begin and after they complete they complete the training. The two observations obtained for each recruit. i.e. before and after measurements constitute natural pairing.

Find several points that are on the graph of the function y = x^2 + 1. Plot the points in a coordinate plane.
Is this a linear function? Explain.
Answer:
Below.
Step-by-step explanation:
Plot following points.
Calculate the point by plugging in values of x into x^2 + 1
for example When x = 0, y = 0^1 + 1 = 1.
So plot plot (0, 1),
Make a table of points to plot:
x -3 -2 -1 0 1 2 3
y 10 5 2 1 2 5 10
When you plot the points you'll see the graph is U shaped.
The function is of second degree (as it contains x^2) so it wont be linear.
