The area of a circle with radius 7 m is 49π m².
What is circle?A circle is a shape or a curve in a plane that has a fixed distance, called the radius, from a given point, called the centre. A circle is also the set of all points that are equidistant from the centre.
Given that, we need to find the area of a circle, with radius 7 m
Area of circle = π × radius²
Area = π × 7²
Area = 49π
Hence, the area of a circle with radius 7 m is 49π m².

Step-by-step explanation:
Admission to a museum is $7.10 per
adult and $4.80 per child. The expression
7.1a 1 4.8c represents the total cost in
dollars for admission for a adults and
c children.
If 6 adults and 6 children attend the
museum, what is the total cost?
The total cost of admission for 6 adults and 6 children to the museum is $71.4.
What is the total cost?Total cost refers to the sum of all costs incurred in producing a product, delivering a service, or achieving a particular outcome. It encompasses all the expenses, both direct and indirect, that are associated with a specific activity, project, or process.
According to the given information:
To calculate the total cost of admission for 6 adults and 6 children to the museum, we can substitute the values of "a" and "c" into the given expression "7.1a + 4.8c" and perform the calculations.
Given:
Number of adults (a) = 6
Number of children (c) = 6
Admission cost per adult = $7.10
Admission cost per child = $4.80
Substituting the values into the expression:
7.1a + 4.8c = 7.1 * 6 + 4.8 * 6
Now, we can perform the calculations:
7.1 * 6 = 42.6
4.8 * 6 = 28.8
Adding the results together:
42.6 + 28.8 = 71.4
So, the total cost of admission for 6 adults and 6 children to the museum is $71.4.

Given right triangle ABCABC with altitude \overline{BD}
BD
drawn to hypotenuse ACAC. If AD=4AD=4 and AC=11,AC=11, what is the length of \overline{AB}
AB
in simplest radical form? (Note: the figure is not drawn to scale.)
Answer:
[tex] x = 2\sqrt{11} [/tex]
Step-by-step explanation:
AD = 4
AC = 11
DC = 11 - 4 = 7
First, find BD using the right triangle altitude theorem:
[tex] BD = \sqrt{AD*DC} [/tex]
Plug in the values
[tex] BD = \sqrt{4*7} [/tex]
[tex] BD = 2\sqrt{7} [/tex]
Use pythagorean theorem to find x:
x² = AD² + BD²
Plug in the values
[tex] x^2 = 4^2 + (2\sqrt{7})^2 [/tex]
[tex] x^2 = 4^2 + (2\sqrt{7})^2 [/tex]
[tex] x^2 = 16 + (4*7) [/tex]
[tex] x^2 = 16 + 28 [/tex]
[tex] x^2 = 44 [/tex]
Take the square root of both sides
[tex] \sqrt{x^2} = \sqrt{44} [/tex]
[tex] x = \sqrt{44} [/tex]
[tex] x = \sqrt{4 * 11} [/tex]

Answer:
x = √2
Step-by-step explanation:
Since this is a 30° 60° 90°, the hypotenuse is 2 times greater than the small leg. We can use this information to make an equation and solve for x.
2x = √8
x = √2
Therefore, x = √2.
A quality control expert at Glotech computers wants to test their new monitors. The production manager claims they have a mean life of 75 months with a standard deviation of 5 months. If the claim is true, what is the probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
Answer:
86.65% probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
Population: [tex]\mu = 75, \sigma = 5[/tex]
Sample of 85: [tex]n = 85, s = \frac{5}{\sqrt{85}} = 0.5423[/tex]
If the claim is true, what is the probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors
This is 1 subtracted by the pvalue of Z when X = 74.4. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{74.4 - 75}{0.5423}[/tex]
[tex]Z = -1.11[/tex]
[tex]Z = -1.11[/tex] has a pvalue of 0.1335
1 - 0.1335 = 0.8665
86.65% probability that the mean monitor life would be greater than 74.4 months in a sample of 85 monitors

There are a few ways to find out the correct answer. One of them is to divide 2.40 by 6 to get a price of one cake and then multiply it by 10:
2.40 ÷ 6 = 0.40
0.40 * 10 = 4.00
Ten cakes would cost 4 pounds.
Answer:

Answer:
The range is between 27.9 minutes and 35.5 minutes.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 31.7 minutes
Standard deviation = 1.9 minutes.
Within what range would you expect 95% of your customers to stay in your store
Within 2 standard deviations of the mean.
Lower bound: 31.7 - 2*1.9 = 27.9 minutes
Upper bound: 31.7 + 2*1.9 = 35.5 minutes
The range is between 27.9 minutes and 35.5 minutes.

What is the surface area of the prism?The surface area of the prism is calculated as
The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism
Surface Area of the prism = 2B + ph
The area of the triangular prism is A = ph + ( 1/2 ) bh
Given data ,
Let the area of the 2 triangles be T
Let the area of the 2 rectangles be R
Let the area of the third side be U
Now , the total surface area of the prism = T + R + U
where T = 2 x ( 1/2 ) ( 16 x 12 )
T = 192 cm²
R = ( 16 x 10 ) + ( 12 x 10 )
R = 280 cm²
And , U = 20 x 10
U = 200 cm²
Therefore , the total surface area of prism S = 192 cm² + 280 cm² + 200 cm²
S = 672 cm²
Hence , the surface area of prism is S = 672 cm²
