a building brick weighs 2.7 kilograms. work out the weight of 840 bricks. give the answer in tonnes
Answer:
2.268 tons
Step-by-step explanation:
Multiply 840 to 2.7 to figure out the weight of 840 bricks.
840 x 2.7 = 2268 kilograms
Convert 2268 kilograms into tons which will be 2.268 tons.
How did I convert? Divide 2268 by 1000 because 1 ton = 1000 kilograms.
Solve for x. 1/2x - 1/4 = 1/2
Answer:
x = 3/2
Step-by-step explanation:
Simplify this equation by dividing all three terms by 1/4:
2x - 1 = 2, or
2x = 3
Then x = 3/2

For males in a certain town, the systolic blood pressure is normally distributed with a mean of 105 and a standard deviation of 7. Using the empirical rule, what percentage of males in the town have a systolic blood pressure between 98 and 112?
Answer:
Answer:
68%
Step-by-step explanation:
The percentage of males in the town who have systolic blood pressure between 98 and 112 is 68%.
What is a normal distribution?It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
For males in a certain town, the systolic blood pressure is normally distributed with a mean of 105 and a standard deviation of 7.
68 percent of the data is within one standard deviation of the mean, i.e. between μ - σ and μ + σ.
μ - σ = 105 - 7 = 98
μ + σ = 105 + 7 = 112
More about the normal distribution link is given below.

Find a formula for the nth term in this
arithmetic sequence
(picture is attached)
please help, thank you
Answer:
nth term: n+6
Step-by-step explanation:
a1 gives -7 and a2 gives -1. Let's compare these two numbers. From -7 to -1, we need a +6. Since -7 + 6 = -1.
a2 to a3, -1 + 6 = 5
a3 to a4, -5 + 6 = 11

find the value of X, round to the nearest 10th
Answer:
4.0731 cm
Step-by-step explanation:
Use pythagorean Theorem which is a^2 + b^2 = c^2 where a and b are the sides of the triangle and c is the hypotenuse, in other words the longest side.
Since x is in line with the center of the circle and is perpendicular with line that measures 15.6 cm we know that one side of the triangle is half of 15.6 or 7.8.
So then we input our known values into the formula and solve for the missing one. The formula looks like this
7.8^2 + b^2 = 8.8^2
solve for b and you get about 4.07431

An FBI agent orders a block of ballistics gel. The gel weighs 54 pounds per cubic foot. What is the weight of the block of gel?
Answer:
22.5 pounds
Step-by-step explanation:
The computation of the weight of the block of gel is shown below:
As we know that
Volume = (length) (width) (height)
= (20) (6 ) (6)
= 720 cubic inches
Now we have to convert into cubic foot
As we know that
1 ft = 12 inches
So 1ft^3 = 12 inches^3
= 1728 inches ^3
Now
= 720 × 1 cubic foot ÷ 1728 cubic inches
= 5 ÷ 12
Now the weight is
= 54 × 5 ÷ 12
= 22.5 pounds

Does the nature of the data allow you describe the difference of the two medians as a multiple of the interquartile range? If so, what is the multiple?
Answer:
1/3
Step-by-step explanation:
From the figure, we know that the median of Amy is 40 and the median of Megan is 35.
Therefore the difference in their medians is = 40 - 35
= 5
We see that Q1 of Megan is 25 and Q3 is 40. Therefore, her interquartile range is given by Q3 - Q1 = 40 - 25
= 15
So, the difference of the medians is the multiple of the interquartile range.
So the multiple is = 5/15
= 1/3 (IQR of Megan)
Answer:
Yes, I can describe the difference of the two medians as a multiple of the interquartile range as shown below.
Step-by-step explanation:
The difference of the medians for the two data sets is 69 − 60 = 9. The interquartile ranges for the data sets are 9 ounces and 8 ounces.
This shows that the difference of the medians is about 1 times, or nearly equal to, the interquartile range of either data set.
For Genivieve, the multiple is 1:
9 = m(9)
m = 1
For Mindy, the multiple is 1.125:
9 = m(8)
m = 1.125

Exercise 1. A batch of 400 containers for frozen orange juice contains 4 that are defective. Two are selected, at random, without replacement from the batch.
(1) What is the probability that the second one selected is defective given that the first one was defective?
(2) What is the probability that both are defective?
(3) What is the probability that both are non-defective?
Answer:
1. 1/13,300
2. 1/13,300
3. 2607/2660
Step-by-step explanation:
Probability is the ratio of the number of possible outcomes to the number of total outcome. The probability that an event will happen added to the probability of the same even not happening is 1.
Given that there are 400 containers of frozen orange juice with 4 that are defective,
non-defective = 400 - 4 = 396
Probability of selecting
Non-defective = 396/400 = 99/100
Defective = 4/100 = 1/100
the probability that the second one selected is defective given that the first one was defective is the same as the probability that both are defective
= 4/400 *3/399
= 1/13,300
the probability that both are non-defective
= 396/400 * 395/399
= 99/100 * 395/399
= 33*79/20*133
= 2607/2660
30^2 + 15^2 = c^2
Use pythagorean theorem
Answer:
c = 33.5
Step-by-step explanation:
[tex]30^{2} + 15^{2} = c^{2}[/tex]
[tex]900 + 225 = c^{2}[/tex]
[tex]1125 = c^{2}[/tex]
(find square root of both sides to get c alone)

solve the following question
Given:
The expressions are:
[tex]\dfrac{2a^2b}{2c^2}\cdot \dfrac{6ac^3}{20b^4}[/tex]
[tex]\dfrac{x^2-y^2}{4x+4y}\cdot \dfrac{x+y}{x-y}[/tex]
To find:
The simplified form of the given expressions.
Solution:
We have,
[tex]\dfrac{2a^2b}{2c^2}\cdot \dfrac{6ac^3}{20b^4}[/tex]
It can be written as:
[tex]\dfrac{2a^2b}{2c^2}\cdot \dfrac{6ac^3}{20b^4}=\dfrac{12a^{2+1}bc^3}{40b^4c^2}[/tex]
[tex]\dfrac{2a^2b}{2c^2}\cdot \dfrac{6ac^3}{20b^4}=\dfrac{3a^{3}c^{3-2}}{10b^{4-1}}[/tex]
[tex]\dfrac{2a^2b}{2c^2}\cdot \dfrac{6ac^3}{20b^4}=\dfrac{3a^{3}c^{1}}{10b^3}[/tex]
Therefore, the value of the given expression is [tex]\dfrac{3a^{3}c}{10b^3}[/tex].
We have,
[tex]\dfrac{x^2-y^2}{4x+4y}\cdot \dfrac{x+y}{x-y}[/tex]
It can be written as:
[tex]\dfrac{x^2-y^2}{4x+4y}\cdot \dfrac{x+y}{x-y}=\dfrac{(x+y)(x-y)}{4(x+y)}\cdot \dfrac{x+y}{x-y}[/tex]
[tex]\dfrac{x^2-y^2}{4x+4y}\cdot \dfrac{x+y}{x-y}=\dfrac{x+y}{4}[/tex]
Therefore, the value of the given expression is [tex]\dfrac{x+y}{4}[/tex].
3. Find the area of a semicircle with a diameter of
30 inches.
Answer:
Answer:
Area of a CIRCLE with radius of 3 inches is
PI * radius^2 =
3.14159265 * 3^2 =
28.27433385 square inches.
Since we are dealing with a SEMI-CIRCLE, we divide that by 2 and get:
14.137166925 square inches which rounds to about
14.14 square inches
Step-by-step explanation:
Answer: 30pi^2 divided by 2
Explanation:
To find the area of a circle, it is pi x radius ^2
Since it is a semicircle 30 is the radius.
pi x radius ^ 2 = 30pi^2
the area would be 30pi^2 divided by 2
