The radius of the circle below is 21 mm.
Calculate the area of the circle.
Give your answer in mm² to 1 d. p.
21 mm
Answer:The area of a circle can be calculated using the formula:
A = πr²
where A is the area and r is the radius.
Plugging in the given radius of 21 mm, we get:
A = π * 21² = π * 441
A = 441π mm²
To 1 decimal place, 441π can be approximated to 1393.1 mm². So, the area of the circle with a radius of 21 mm is approximately 1393.1 mm² to 1 decimal place.

1/8 of the toys in a play area are yellow, and 1/4 are green. 3/5 of the remainder are red. The rest of the toys are blue. If there are 100 green toys, how many blue toys are there?
A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
To figure out what fraction of the toys are blue, we need to convert all of the fractions to have a common denominator.
What is a common denominator?A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.
Looking at the fractions, we can see that there are 3 fractions, [tex]\frac{1}{8}, \frac{1}{4}[/tex] and [tex]\frac{3}{5}[/tex].
To solve for the common denominator between [tex]\frac{1}{8}[/tex] and [tex]\frac{3}{5}[/tex], we first multiply the denominators, 8 and 5.
8 × 5 = 40We now know that the denominator is going to be 40.
[tex]\frac{?}{40} \frac{?}{40}[/tex]To get the numerators, we can use these equations:
1 × 5 = 58 × 3 = 24The new fractions look like this:
[tex]\frac{5}{40} \frac{24}{40}[/tex]To easily convert the last fraction ([tex]\frac{1}{4}[/tex]) we can multiply the numerator and denominator by 10.
1 × 10 = 104 × 10 = 40Why do we multiply by 10?We multiply by 10 because the denominator, which is 4, can be multiplied by 10 to get our common denominator of 40.
Now, we have our 3 fractions converted to have common denominators.
([tex]\frac{5}{40}, \frac{24}{40}[/tex] and [tex]\frac{10}{40}[/tex])
(Yellow, red, and green)
We can now add these up and see what fraction of blue is remaining.
[tex]\frac{5}{40}+ \frac{24}{40}+ \frac{10}{40} =\frac{39}{40}[/tex][tex]1 - \frac{39}{40} = \frac{1}{40}[/tex]Therefore, the fraction of blue toys compared to the total amount is [tex]\frac{1}{40}[/tex].
If there are 100 green toys resulting in [tex]\frac{10}{40}[/tex] of all the toys, we can divide 100 by 10 to get the number of blue toys.
Why do we divide by 10?We divide by 10 because [tex]\frac{1}{40}[/tex] is only [tex]\frac{1}{10}[/tex] of [tex]\frac{10}{40}[/tex], meaning we divide by 10.
100 ÷ 10 = 10Therefore, there are 10 blue toys.
Answer:
1/4=100
10/40=100
40/40=400
1/8=400/8=50
3/5=400/5*3=240
400-100-50-240=10
10 of the toys are blue

Bashir has a toy car collection. He keeps some in display case and the rest on the wall. 136 of his toys are on the wall and 15% of the toys are in the display what is the total number of toys in barshirs collection
The total number of toys in Bashir's collection is 160.
How to find the total number of toys in Bashir's collection?
A percentage is a number or ratio that can be expressed as a fraction of 100.
Let N represent the total number of toys in Bashir's collection
Since 136 of his toys are on the wall and 15% of the toys are in the display. We can write:
136 + (15% of N) = N
136 + (15/100 * N) = N
136 + 0.15N = N
N - 0.15N = 136
0.85N = 136
N = 136/0.85
N = 160

A pool measuring 16 meters by 28 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the pool and the path combined is 864 square meters, what is the width of the path?
Let the width of the path be represented by x.
The total width of the pool and the path would then be 16 + 2x (for the two shorter sides) and 28 + 2x (for the two longer sides).
The area of the pool itself is 16 × 28 = 448 square meters.
The area of the combined pool and path is 864 square meters.
So the area of just the path is:
864 - 448 = 416 square meters
The area of the path can also be expressed as the area of the larger rectangle (16 + 2x) × (28 + 2x) minus the area of the pool (16 × 28).
So we can set up the equation:
(16 + 2x) × (28 + 2x) - 448 = 416
Expanding the left side and simplifying:
4x^2 + 88x - 480 = 0
Dividing by 4:
x^2 + 22x - 120 = 0
Using the quadratic formula:
x = (-22 ± sqrt(22^2 - 4(-120)))/2
x = (-22 ± 26)/2
x = 2 or x = -24
The width of the path cannot be negative, so the width of the path is 2 meters.

A building casts a shadow 5 ft long. At the same time, the shadow cast by a vertical yardstick is 5 ft long. How tall is the building?
Answer: Let's call the height of the building "h".
The length of the shadow cast by the building is 5 feet, and the length of the shadow cast by the yardstick is also 5 feet. This means that the ratio of the height of the building to the length of its shadow is the same as the ratio of the height of the yardstick to the length of its shadow.
h / 5 = 1 / 5
Cross-multiplying, we get:
h = 5 * 1 / 5
h = 1
So the building is 1 foot tall.

Suppose that Motorola uses the normal distribution to determine the probability of defects and the number of defects in a particular production process. Assume that the production process manufactures items with a mean weight of 10 ounces. Calculate the probability of a defect and the suspected number of defects for a 1,000-unit production run in the following situations.
(a) The process standard deviation is 0.25, and the process control is set at plus or minus one standard deviation. Units with weights less than 9.75 or greater than 10.25 ounces will be classified as defects. If required, round your answer for the probability of a defect to four decimal places and for the number of defects to the nearest whole number.
Probability of a defect:
Number of defects:
The probability of a defect is 5.7330 x [tex]10^{-5}[/tex] and the number of defects is 5.73.
To calculate the probability of a defect, we need to find the area under the standard normal curve that lies outside of the process control limits of 9.75 ounces and 10.25 ounces. We can use the standard normal distribution table to find this area.
First, we need to standardize the weight limits as follows -
[tex]Z_{lower}[/tex] = (9.75 - 10) / 0.25 = -4
[tex]Z_{upper}[/tex] = (10.25 - 10) / 0.25 = 4
Next, we will find the area under the standard normal curve that lies outside of these limits as follows -
P(Defect) = P(Z < -4) + P(Z > 4)
Using a standard normal distribution table, we can find that P(Z < -4) = 2.8665 x [tex]10^{-5}[/tex] and P(Z > 4) = 2.8665 x [tex]10^{-5}[/tex] .
So, the total probability of a defect is -
P(Defect) = 2.8665 x [tex]10^{-5}[/tex] + 2.8665 x [tex]10^{-5}[/tex] = 5.7330 x [tex]10^{-5}[/tex]
Finally, we will find the number of defects for a 1,000-unit production run as follows -
The number of defects = 1000 * 5.7330 x [tex]10^{-5}[/tex] = 5.73 (rounded to the nearest whole number).

How can I find the area under the normal distribution between z= -0.30 and z=0.90?
To find the area under the normal distribution between z = -0.30 and z = 0.90, you can use a standard normal distribution table or a calculator with a normal distribution function.
Using a standard normal distribution table:
Look up the area to the left of z = 0.90 in the standard normal distribution table. This will give you a value of 0.8159.
Look up the area to the left of z = -0.30 in the standard normal distribution table. This will give you a value of 0.3821.
Subtract the value from Step 2 from the value from Step 1 to find the area between z = -0.30 and z = 0.90:
Area = 0.8159 - 0.3821 = 0.4338
Using a calculator with a normal distribution function:
Use the normal distribution function on your calculator with a mean of 0 and a standard deviation of 1 to find the area to the left of z = 0.90. This will give you a value of 0.8159.
Use the normal distribution function on your calculator with a mean of 0 and a standard deviation of 1 to find the area to the left of z = -0.30. This will give you a value of 0.3821.
Subtract the value from Step 2 from the value from Step 1 to find the area between z = -0.30 and z = 0.90:
Area = 0.8159 - 0.3821 = 0.4338
Therefore, the area under the normal distribution between z = -0.30 and z = 0.90 is 0.4338.

Convert to scientific notation.
0.000000032
Answer:
3.2 × 10⁻⁸
Step-by-step explanation:
Scientific notation is written in the form [tex]a \times 10^n[/tex], where [tex]1 \leq a < 10[/tex] and [tex]n[/tex] is any positive or negative whole number.
To convert a number into scientific notation, move the decimal point to the left or right until there is one non-zero digit to the left of the decimal point.
The number of times you have moved the decimal point is the power of 10 (the value of n).
If the decimal point has moved to the left, n is positive.If the decimal point has moved to the right, n is negative.Therefore, to convert 0.000000032 to scientific notation, move the decimal point 8 places to the right so that [tex]a[/tex] is 3.2.
As the decimal point has been moved 8 places the right, the exponent of 10 is -8.
Therefore, 0.000000032 = 3.2 × 10⁻⁸.

f(x)=c(1/4)^x , x = 1, 2, 3, . ... d. f(x) = c(x + 1)², x = 0, 1, 2, 3. e. f(x) = x/c, x = 1, 2, 3, ... , n. f. f(x) = c/(x + 1) (x + 2), = 0, 1, 2, 3, ... . Hint: In part (f), write f(x) = 1/(x + 1) − 1/(x + 2).
For each of the functions, the constant c was determined so that the function would satisfy the conditions of being a pmf for a random variable X, and then a line graph was plotted for each pmf.
