A right square pyramid is shown.
The height is 10 centimeters and the side length of the base is 16 centimeters. What is the length, in centimeters (cm), of s?
Given the height and the side length of the square pyramid, the length of s is 12.81 cm.
What is the length of s?A square pyramid is a three-dimensional object that is made up of a square base and four triangular bases that are joined together at a vertex.
S in the diagram represents the slant height of the square pyramid.
The formula that can be used to determine the slant height is:
s² = r² + h².
Where:
r = side length / 2 = 16/2
s = √8² + 10²

Solve for x.
Answer:
x = 28.744
Step-by-step explanation:
Seeing as this is a right triangle, and you're given an angle, an unknown measurement to the opposite side, and the measure of the adjacent side. You can use trig functions. In this case, tangent, because you are given the opposite and adjacent, and tangent covers opposite/adjacent.

Students are voting on the color of T-shirts to wear on their field trip. There are 160 students-65 boys and 95 girls-going
on the field trip. A random sample of students is chosen. Surveying the random sample produced a representative
sample of the population. Which was most likely true of the representative sample?
The representative sample contained all 160 students.
O The representative sample contained more boys than girls.
The representative sample contained more girls than boys.
O The representative sample contained an equal number of boys and girls.
Answer:
more girls than boys.
Step-by-step explanation:
because there is 95 girls compared to 65 boys, so whatever random numbers of both are pulled, girls will have the higher ratio.

A) 42xy
B) 28x + 2y
C) 11x + 2y
D) 28x + 14y
Answer:
D) 28x + 14y
Step-by-step explanation:
7(4x + 2y)

Step-by-step explanation:
Use a distributive property.
Distributive property:
⇒ A(B+C)=AB+AC
⇒ 7(4x+2y)
Multiply by expanding.
⇒ 7*4x=28x
⇒ 7*2y=14y
Then, rewrite the problem.
⇒ = 28x+14y

The crime rate of a certain city is increasing by exactly 6% each year. If there were 550
crimes in the year 1990 and the crime rate remains constant each year, determine the approximate number of crimes in the year 2016.
Round to the nearest whole number.
Using an exponential function, it is found that the approximate number of crimes in the year of 2016 was of 2502.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growth rate, as a decimal.In this problem, there were 550 crimes in the initial year observed, and the growth rate is of 6%, hence the parameters are A(0) = 550, r = 0.06, and the equation is given by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
[tex]A(t) = 550(1 + 0.06)^t[/tex]
[tex]A(t) = 550(1.06)^t[/tex]
2016 is 26 years after 1990, hence:
[tex]A(26) = 550(1.06)^{26} \approx 2502[/tex]
The approximate number of crimes in the year of 2016 was of 2502.

Dean Halverson recently read that full-time college students study 20 hours each week. She decides to do a study at her university to see if there is evidence that students study an average of less than 20 hours each week. A random sample of 33 students were asked to keep a diary of their activities over a period of several weeks. It was found that he average number of hours that the 33 students studied each week was 17. 7 hours. The sample standard deviation of 3. 9 hours. Find the p -value. The p -value should be rounded to 4-decimal places
Using the t-distribution, as we have the standard deviation for the sample, it is found that the p-value is of 0.0009.
What are the hypotheses tested?At the null hypothesis, it is tested if the students study 20 hours, that is:
[tex]H_0: \mu = 20[/tex].
At the alternative hypothesis, it is tested if they study less than 20 hours, that is:
[tex]H_1: \mu < 20[/tex].
What is the test statistic?The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.In this problem, the values of the parameters are given as:
[tex]\overline{x} = 17.7, \mu = 20, s = 3.9, n = 33[/tex].
Hence, the value of the test statistic is:

What is the total area of the three triangles? 12.5 square units 13 square units 13.5 square units 14 square units
The area of the considered 3 triangles is given by: Option B: 13 sq. units.
How to find the area of a triangle whose vertices' coordinates are given?Suppose the vertices of the considered triangle ABC are on [tex]A(A_x,A_y), B(B_x,B_y), C(C_x,C_y)[/tex], then, the area of the triangle is given by:
[tex]Area = \dfrac{|A_x(B_y-C_y) + B_x(C_y-A_y) + C_x(A_y-B_y)|}{2}[/tex]
For this case, the missing image is attached below.
The second and third triangle are easy as their base and height are parallel to x or y axis.
We will find area of third triangle by coordinates of its vertices.
Getting area of first triangle:
Coordinates of A : (4,10)Coordinates of B : (5,7)Coordinates of C : (7,8)Thus, we get:
[tex]Area_{ABC} = \dfrac{|4(7-8) + 5(8-10) + 7(10-7)|}{2} = \dfrac{7}{2} = 3.5 \: \rm unit^2[/tex]
Area of second triangle = [tex]\dfrac{|RS| \times h}{2}[/tex]base, and h is the perpendicular line connecting from line RS and the vertex T
From figure we see:
|RS| = 3 units, h = 3 units
Thus, area of second triangle = [tex]3 \times 3 /2 = 4.5 \: \rm unit^2[/tex]
Area of third triangle = [tex]\dfrac{|XY| \times h}{2}[/tex] where XY is base, and h is the perpendicular line connecting from line XY and the vertex Z
From figure we see:
|XY| = 5 units, h = 2 units
Thus, Area of third triangle = [tex]5 \times 2 /2 = 5 \: \rm unit^2[/tex]
Total area = 3.5 + 4.5 + 5 = 13 sq. units
Thus, the area of the considered 3 triangles is given by: Option B: 13 sq. units.

Write an equation of the line that passes through (0, 0) and (2, 6).
Answer:
y=3x
Step-by-step explanation:
hello :
an equation is : y=ax ( the line that passes through (0, 0) )
and (2, 6): x= 2 y=6 qo : 6 = a ×2 a =3
an equation of the line that passes through (0, 0) and (2, 6) is : y=3x
The equation of the line passing through the points (0, 0) and (2, 6) is:
y = 3x.
What is the equation of a line?The equation of a line is a relation between the dependent variable y and an independent variable x, used to determine the value of y for a given x. The general form of such an equation is,
y = mx + b, where m is the slope and b the y-intercept.
What is the two-point formula?The two-point formula is the formula used to determine the equation of a straight line when the slope m and the y-intercept b are not given, but we know two points on the line.
The formula is such: y-y₁ = ((y₂-y₁)/(x₂-x₁))*(x-x₁).
How do we solve the given question?We have been given two points on the required line, (0, 0) and (2, 6)
We take the points as (x₁, y₁), and (x₂, y₂) respectively.
∴ x₁ = 0, x₂ = 2, y₁ = 0, y₂ = 6.
Since it's an equation of a line, we use the two-point method to determine the equation.
The two-point formula is:
y-y₁ = ((y₂-y₁)/(x₂-x₁))*(x-x₁)
Substituting the values we have, we get:
y - 0 = ((6-0)/(2-0))*(x-0)
or, y = 3x.
∴ The equation of the line passing through the points (0, 0) and (2, 6) is:
y = 3x.
