x=-3y+3
x-3y=-15
Answer:
x = -6
y = 3
Step-by-step explanation:
Since we are given what x equals, we will plug that in first to the second equation.
(-3y+3) - 3y = -15
Solve by combining like-terms and isolating y.
-6y + 3 = -15
-6y = -18
y = 3
Now plug in y to the first equation to solve for x.
x = -3(3) + 3
x = -9 + 3
x = -6

Each side of a cube is 4 inches long. What surface area of the cube
Answer:
96 in^2
Step-by-step explanation:
This is because u have to multiply the two bases and the lateral sides to get your area
Answer:
96
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces.
Area = l x w
4 x 4 = 16
16 x 6 = 96

Write in radical form
Step-by-step explanation:
I'll do one for you.
Using the formula for turning exponents into radicals
[tex](b) {}^{ \frac{x}{y} } = \sqrt[y]{b} {}^{x} [/tex]
where b is the base
This means that the numerator in the exponet form becomes the power under the radical in radical form and
the denominator in exponet form becomes the nth root in radical form.
For example 5,
[tex](5) {}^{ \frac{ - 3}{5} } [/tex]
That becomes in radical form
[tex] \sqrt[5]{5 {}^{ - 3} } [/tex]
or if you want to write it using positive exponents
[tex] \frac{1}{ \sqrt[5]{5 {}^{3} } } [/tex]
I'll do one more for you
For example 6,
[tex]11 {}^{ \frac{4}{3} } [/tex]
That becomes in radical form
[tex] \sqrt[3]{11 {}^{4} } [/tex]
PLEASE HELP ME I WILL GIVE ALL MY POINTS!!! 1440 tons of grain were brought to a silo over 2 days. On the second day, 80% of the amount of the delivered during the first day was brought in. How many tons of grain were delivered to the silo on the first day?
Answer:
800 tonsStep-by-step explanation:
Let the amount brought in the first day be x
In the second day brought:
80% of x = 0.8xTotal in two days:
1440 tonsSolve the following equation for x:
x + 0.8x = 14401.8x = 1440x = 1440/1.8x = 800 tonsWhat is the least common multiple of 3 and 10?

Step-by-step explanation:
If a man walks at the rate of 3 feet per second, how many minutes will it take him to walk 5760 feet?
Answer:
32 minutes
Step-by-step explanation:
There are 60 seconds in a minute
That means we will need to know how many feet he walks in a minute
So we would do 3 x 60 which equals 180 so he walks 180 ft per miute
Now we need to figure out how many minutes it took for him to walk 5760 ft.
So we would do 5760 ÷ 180 which equals 32
So the aswer is 32 minutes for him to walk 5760 ft.
Hope this helps
b is the midpoint of ac. if ab=8x-7 bc=6x+7 find ac
Answer: AC = 98
Step-by-step explanation:
A midpoint is a point on a line segment that divides it into two equal parts.
This means AB = BC
AB = 8x - 7
BC = 6x + 7
AB = BC
8x - 7 = 6x + 7
Solve this to find x
Add 7 to both sides
8x = 6x + 14
Subtract 6x from both sides
2x = 14
Divide both sides by 2
x = 7
Now AC = AB + BC
AC = AB + BC
AC = 8x - 7 + 6x + 7
AC = 14x
Substitute 7 for x
AC = 14(7)
AC = 98
Hope this helps!

case study
a test was conducted in the school for class 7 to test their knowledge out of 30 marks for 15 students their scores
21,16,30,15,16,18,10,24,26,20,19,24,24,25,23,
1) find the range of the above information
a) 24 b) 21 c) 10 d) 16
2) find the average score
a) 279 b)289.33 c) 289.53 d) 289.55
3) find the median
a) 20 b) 21 c) 19 d) 18
Given:
The data set is
21, 16, 30, 15, 16, 18, 10, 24, 26, 20, 19, 24, 24, 25, 23
10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30
To find:
The range, average and median for the given data set.
Solution:
Arrange the data set in ascending order.
10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30
(1)
Range = Maximum value - Minimum value
= 30 - 10
= 20
Therefore, the range of the given data set is 20. All the options are incorrect.
(2)
[tex]Average=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}[/tex]
[tex]Average=\dfrac{311}{15}[/tex]
[tex]Average\approx 20.73[/tex]
Therefore, the average score is about 20.73. All the options are incorrect.
(3)
Number of observations = 15, which is odd.
[tex]Median=\dfrac{n+1}{2}\text{th term}[/tex]
[tex]Median=\dfrac{15+1}{2}\text{th term}[/tex]
[tex]Median=\dfrac{16}{2}\text{th term}[/tex]
[tex]Median=8\text{th term}[/tex]
In the arranged data set 8th term is 21.
[tex]Median=21[/tex]
Therefore, the correct option is b.
The union representing the Bottle Blowers of America (BBA) is considering a proposal to merge with the Teamsters Union. According to BBA union bylaws, at least three-fourths of the union membership must approve any merger. A random sample of 2,000 current BBA members reveals 1,600 plan to vote for the merger proposal. What is the estimate of the population proportion
Answer:
The answer is "(0.782, 0.818)".
Step-by-step explanation:
computing the sample proportion:
[tex]p=\frac{x}{n}= \frac{1,600}{2000}=0.80 \\\\[/tex]
[tex]\text{Computing the} \ 95\% \ \ C.I \\\\[/tex]
[tex]C.I= p \pm Z_{\frac{\alpha}{2}}\sqrt{\frac{P(1-p)}{n}}[/tex]
[tex]= 0.80 \pm 1.96 \sqrt{\frac{0.80(1-0.80)}{2000}} \\\\= 0.80 \pm 1.96 \sqrt{\frac{0.80(0.20)}{2000}} \\\\= 0.80 \pm 1.96 \sqrt{\frac{0.16}{2000}} \\\\ = 0.80 \pm 1.96 \sqrt{0.00008} \\\\=0.80 \pm 0.18 \\\\= (0.782, 0.818)[/tex]
conclusion:
Since the interval calculation contains higher values than 75 percent of its union membership, the merger proposal is likely to pass.
