how many questions out of 42 do I need to get right to score 75?
Answer:
31 questions, but it's impossible to score 75%.
Step-by-step explanation:
It's impossible to get exactly a score of 75% out of 42 questions. However, you can get the next closest percentage, which is rounded up to 74% with 31 questions right out of 75.
This is because 31 / 42 = 0.738... You can round 0.738 to 0.74. Then multiply 0.74 by 100, which gives you 74. This means the closest score you can get to 75 is 74% with 31 questions.
You can also score 76% with 32 questions right out of 42 questions. This is because 32 / 42 = 0.761... You can round 0.761 to 0.76. Then multiply 0.76 by 100, which gives you 76.
Today, everything at a store is on sale. The store offers a 18% discount.
a. The regular price of a T-shirt is $20. What is the discount price?
Answer:
Discount : 3.60$
Discounted shirt price: 16.40$
Step-by-step explanation:
If there is a 18% then we can get the discounted price you get by multiplying 20$ by 18%
So we can change 18% to decimal if we need to by just moving a decimal point 2 decimal points to the left. so .18.
Now 20*.18 = 3.60$ | That is the discount you get on sale. To get the actual discount price you just need to subtract 20-3.6= 16.40$
Answer:
Step-by-step explanation:
To calculate the 18% discount, convert 18% into the equivalent decimal fraction 0.18 and then multiply the regular price ($20) by 0.18; the discount is thus $3.60.
Subtract the discount, $3.60, from the regular price ($20) to obtain the discount price: $16.40.
********************************
Alternatively, take the shortcut of multiplying $20 by (1.00 - 0.18), or
$20 by 0.82. The result (i. e., the discount price) is the same: $16.40

Find the zeros of y = x2 - 6x – 4 by completing the square.
O A. x = 3 + 5
B. X = +3
C. X = 3 + 13
D. x.-3113
Answer:
√13 + 3 = x
-√13 + 3 = x
Step-by-step explanation:
y = x² - 6x - 4
0 = x² - 6x - 4
0 + 13 = x² - 6x - 4 + 13
13 = x² - 6x + 9
13 = (x-3)²
±√13 = x-3
±√13 + 3 = x
√13 + 3 = x
-√13 + 3 = x

Step-by-step explanation:
Suppose an urn has six balls, three red, two blue, and one yellow. On any draw from the urn, all balls in the urn are equally likely to be drawn. Suppose that two balls are drawn, in sequence without replacement, that is, the second ball is drawn without replacing the first ball in the urn. What is the probability that the second ball drawn is blue
Answer:
1 / 3
Step-by-step explanation:
Number of balls :
Red, R = 3 ; Blue, B = 2 ; Yellow, Y = 1
Total = 6
From two draws without replacement, probability that 2nd draw is blue :
Possibilities :
P(RB) or P(YB) or P(BB)
P(RB) = 3/6 * 2/5 = 6/30
P(YB) = 1/6 * 2/5 = 2 /30
P(BB) = 2/6 * 1/5 = 2 / 30
HENCE,
P(RB) + P(YB) + P(BB)
6/30 + 2/30 + 2/30 = 10/30 = 1/3

The amount that two groups of students spent on snacks in one day is shown in the dot plots below.
Group A
A dot plot titled Group A. A number line going from 0 to 5 labeled Amount in Dollars. There are 0 dots above 0, 5 above 1, 4 above 2, 1 above 3, and 0 above 4 and 5.
Group B
A dot plot titled Group B. A number line going from 0 to 5 labeled Amount in Dollars. There are 0 dots above 0, 3 above 1, 2 above 2, 4 above 3, 0 above 4, and 1 above 5.
Which statements about the measures of center are true? Select three choices.
O The mean for Group A is less than the mean for Group B.
O The median for Group A is less than the median for Group B.
O The mode for Group A is less than the mode for Group B.
O The median for Group A is 2.
O The median for Group B is 3.
Answer:
A, B, and C
not D or E
Step-by-step explanation:
A: the mean is 1.6 for group A compared to 2.5 of group B
B: the median is 1.5 for group A compared to 2.5 of group B
C: the mode is 3 for A and the mode is 5 for B
therefor, abc :)
The three statements that are true about the measures of the centre are:
The median for Group A is 2.
The median for Group B is 3.
The mode for Group A is less than the mode for Group B.
What are the mode, median, and mean?We must tally up every dollar spent and divide it by the number of pupils in each group to determine the mean for each group.
The dot plots show that Group A is expected to have a mean that is lower than Group B because Group A has more values that are less than $2, which will lower the average.
Yet, based just on the dot plots, we cannot be certain of the precise values of the means. The claim "The mean for Group A is less than the mean for Group B" is therefore not always accurate.
When the data are organized in order, the median is the middle value. The dot plots show that Group A's median is 2 and Group B's median is 3, respectively. It follows that the claim "The median for Group A is less than the median for Group B" is untrue.
The value that appears the most frequently is the mode. The dot plots demonstrate that Group A has a mode of 1, while Group B has a mode of 3. The adage "The mode for Group A is less than the mode for Group B" is therefore accurate.

What is the diameter of a hemisphere with a volume of 272\text{ m}^3,272 m
3 , to the nearest tenth of a meter?
Answer:
D = 10.1m
Step-by-step explanation:
We know that the volume of a sphere of radius R is:
V = (4/3)*pi*R^3
where pi = 3.14
A hemisphere is half a sphere, then the volume of an hemisphere is half of the volume of a sphere, then the volume of a hemisphere of radius R is:
V' = (1/2)*(4/3)*pi*R^3
Now, we know that our hemisphere has a volume:
V' = 272m^3
Then we can solve the equation:
272m^3 = (1/2)*(4/3)*pi*R^3
For R.
(we want the diameter, but remember that the diameter is equal to two times the radius, so finding the radius is a good start)
272m^3 = (1/2)*(4/3)*pi*R^3
272m^3 = (4/6)*3.14*R^3
272m^3*(6/4*3.14) = R^3
∛( 272m^3*(6/4*3.14) ) = R = 5.06 m
And the diameter is two times that, so we get:
D = 2*5.06m = 10.12 m
Rounding this to the nearest tenth of a meter (first digit after the decimal dot), we get:
D = 10.1m

A man borrows $500 and agrees to repay $750 at the end of 4 years. What is the rate of simple interest charged?
Answer:
The rate of simple interest is 0.125, or 12.5%.
Step-by-step explanation:
If the man must repay $750 after 4 years on a $500 loan, the simple interest would be ($750-$500), or $250.
The simple interest formula is i = p*r*t. Solving this for the interest rate, r, yields
i
r = ----------
p*t
and so, with i = $250, p = $500 and t = 4 yr, we find r as follows:
$250
r = ----------------- = 0.125
$500*4
The rate of simple interest is 0.125, or 12.5%.

The total cost of the set using the hire purchase plan. *
How much can be saved by paying cash? *
Write the savings as a fraction of the cash price in its lowest terms.
Answer:
The correct answer is -
1. $115
2. 15 (each of $25) that equal to $375
3. $490
4. $30
Step-by-step explanation:
As given in the picture related to the given question, there are two ways one can get a color television, one by the cash price of $460 or by the renting plan of 25% of the price as a deposit and the rest in a15 equal payments of $25.
Then the amount of deposit would be :
$460*25/100
= $115
It is given in the image attached that there must be 15 payments (each of $25) after the deposit.
The total amount one has to pay using hire purchase plan is :
= deposit + total money by monthly payments
= 115 + 375
= $ 490
By using cash price one can save -
= total cost using the rental plan - cash price
= 490 - 460
= $ 30
sam wants to fence his rectangular garden plot along its length on the front side. The perimeter of the plot is 24 meters, and its length is 3 times its width
Answer:
Length: 12 meters
Step-by-step explanation:
Step 1:
Let us start with the formula of the perimeter of a rectangle, [tex]P=2l+2w[/tex], where l represents the length of the rectangle, and w represents the width of the rectangle.
We can set width as variable x. We are also given that the length is three times the width, hence it can be represented as 3x.
Step 2:
We can now write our equation and solve for x :
[tex]24=2x+2*2x\\24=2x+4x\\24=6x\\x=\fbox{4}[/tex]
We set x as width, so the width is 4 meters. However, in this problem we are looking for the length. The length is three times the width, so it would be [tex]\fbox{12}[/tex] meters.
I hope this helps! Let me know if you have any questions :)
Answer:
From the given information, there are two equations in terms of x and y:
2x + 2y = 24 (perimeter of the rectangular plot)
x = 3y (relationship between length and width)
The second equation is expressed in terms of x, so directly substitute the value of x into the first equation and find y:
2(3y) + 2y = 24
y = 3
Substitute y in the second equation to find x:
x = 3(3)
x = 9
The fencing cost is $25 multiplied by the length of the side Sam wants to fence: 25 × 9 = 225. Therefore, Sam needs to spend $225 to fence that side of his plot.

what is the equation of the line that is perpendicular to the line y = − x / 2 + 4 / 5 and passes through the point ( − 2, 6 ).
pls answer quickly
Answer:
y = 2x + 10
Step-by-step explanation:
Equation of the line is;
y = −(x/2) + (4/5)
Slope here is m = -½ following the equation y = mx + c
Now, for a line perpendicular to it, the slope will now be; m = -1/(-½) = 2
To pass through the point ( − 2, 6 ), let's find C and it will be;
6 = 2(-2) + c
6 = -4 + c
c = 6 + 4
c = 10
Thus equation is;
y = 2x + 10
