Huw is paid a weekly wage.
Every week he:
saves
1/5 of his wage,
spends 70% of the money he has left on his living expenses,
spends all that remains on his social life.
One week, Huw saves £40.
How much does Huw spend on his social life?
_____%
Answers
= 40 x 5
= £200
As he saves £40,
so the amount of money he spends on his living expenses
= (200-40) x 70%
= £112
The amount of money he spends on his social life
= 200 - 40 - 112
= £48
The percentage of the money he spends for his social life
= 48/200 x 100%
= 24%

A large high school has been waging a campaign against drug use, particularly marijuana. Before the campaign began in
2007, a random sample of 100 students had their lockers checked for drugs. In 27 of the lockers, marijuana was found.
To assess if the program has been successful, another random locker check was conducted in 2017. This time, 30 out of
175 students had marijuana in their lockers. Using a = 0.05, is there evidence to suggest that the proportion of students
who are found with marijuana in their lockers has decreased?
Answers
Using the z-distribution, as we are working with a proportion, it is found that there is evidence that the proportion has decreased.
What are the hypothesis tested?At the null hypothesis, it is tested if the proportion is still the same, of 27/100 = 0.27, hence:
[tex]H_0: p = 0.27[/tex]
At the alternative hypothesis, it is tested if the proportion has decreased, hence:
[tex]H_1: p < 0.27[/tex].
What is the test statistic?The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.In this problem, the parameters are as follows:
[tex]n = 175, \overline{p} = \frac{30}{175} = 0.1714[/tex]
Hence, the value of the test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.1714 - 0.27}{\sqrt{\frac{0.27(0.73)}{175}}}[/tex]
z = -2.94.
What is the decision?Considering a left-tailed test, as we are testing if the propoortion is less than a value, the critical value is of [tex]z^{\ast} = -1.645[/tex].
Since the test statistic is less than the critical value for the left-tailed test, it is found that there is evidence that the proportion has decreased.

6 times 2.5 is 15
so that means 20 also has to be multiplied by 2.5
which becomes 50
Answer: B. 50 feet
Step-by-step explanation:
We can set up a proportion. x will be the length of the second rectangle, I will have width on the bottom (denominator) and length on the top (numerator). All units are in feet:
[tex]\frac{20}{6} =\frac{x}{15}[/tex]

300 = 6x
50 = x
x = 50

The dimensions of a cone are shown in the figure below. What is the approximate volume, in cubic centimeters, of the cone?
Answers
Answer:
B or 415
Step-by-step explanation:
the volume of a cone is given by the formula V = (pi × r^2 × h/3)
where,
V = volume of the cone,
r = the radius of the cone,
h = the height of the cone.
so by just plugging in the values we get the answer which is 415
if you need any further guidance make sure to ask. :)
The Volume of Cone is 414.48 cm³.
What is Volume?Every three-dimensional item requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an object inside the confines of three-dimensional space. It is also known as the object's capacity.
We have,
radius = 6 cm
height = 11 cm
Now, slant height
= √r² + h²
= √11² + 6²
= √121+ 36
= √157
= 12.52 cm
Now, Volume of cone
= 1/3 πr²h
= 1/3 (3.14)(6)²(11)
= 1/3 (3.14)(36)(11)
= 414.48 cm³

y = mx + b
y is his height during that year
x is the number of months
m is the slope or rate of change, which is 1/2 inch every month
b is the y-intercept, which is 30 inches
plug everything in then you get:
y = 1/2x + 30

Hey there!
3(2x + 4y) - y
= 3(2x + 4y) - 1y
= 3(2x) + 3(4y) - 1y
= 6x + 12y - 1y
= 6x + 11y
LETS TEST OPTION D. FOR YOUR RESULT…
Option D.
6(x + 2y) - y
= 6(1x + 2y) - 1y
= 6(1x) + 6(2y) - 1y

6x + 11y = 6x + 11y which makes this statement TRUE ☑️
Therefore, your answer is:
