Answer:
44 cm^2
Step-by-step explanation:
A = area of rectangle + area of triangle
Look at the triangle. It has a base of 8 cm. we need the height.
Half of the trianfgle is a right triangle with hypotenuse 5 cm and leg 4 cm. Using the well-known Pythagorean triple 3, 4, 5, the other leg is 3 cm. That is the height of the triangle.
A = LW + (1/2)bh
A = 8 cm * 4 cm + (1/2)(8 cm)(3 cm)
A = 32 cm^2 + 12 cm^2
A = 44 cm^2

Vertices (V) = 8
Faces (F) = 6
Edges (E) => F + V - E = 2 (EULER'S FORMULA)
so 6 + 8 - 2 = E => E = 12
now just look at options
and however its a common thing that if Vertices are 8 and Faces are 6 and Edges are 12 then it is cube or cuboid
and another name of cuboid is rectangular prism ;)
hence answer is option c - rectangular prism

Answer:
Length of hypotenuse JH = 9.2 unit (Approx.)
Length of perpendicular JG = 6.5 unit
Step-by-step explanation:
Given:
Length of base GH = 6.5 unit
Angle of H = 45°
Find:
Length of perpendicular JG
Length of hypotenuse JH
Computation:
Using trigonometry function:
Tan θ = Perpendicular / Base
Tan 45 = Perpendicular / 6.5
1 = Perpendicular / 6.5
Perpendicular = 6.5
Length of perpendicular JG = 6.5 unit
hypotenuse = √perpendicular² + base²
Length of hypotenuse JH = √6.5² + 6.5²
Length of hypotenuse JH = √42.25 + 425.25
Length of hypotenuse JH = √84.5
Length of hypotenuse JH = 9.1923
Length of hypotenuse JH = 9.2 unit (Approx.)

A school has found from past records that the average scores for boys is 75 in a sample of 45 boys, and the average scores for girls is 85 in a sample of 30 girls. The population standard deviations for boys' and girls' scores were 25 and 17, respectively. The 90% confidence interval for the difference of the population means is approximately (_____, −2.022). Assume that the distributions of the scores of men and women are normally distributed. Round your answer to two decimal places.

90% confidence zc=1.645
95% confidence zc=1.96
99% confidence zc=2.576
Answers
Answer:
The 90% confidence interval for the difference of the population means is approximately (-17.98, -2.02).
Step-by-step explanation:
Before building the confidence interval, we need to understand the central limit theorem and subtraction of normal variables.
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.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
Subtraction between normal variables:
When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.
Boys:
Mean of 75, sample of 45, standard deviation of 25.
This means that [tex]\mu_B = 75, s_B = \frac{25}{\sqrt{45}}[/tex]
Girls:
Mean of 85, sample of 30, standard deviation of 17.
This means that [tex]\mu_G = 85, s_G = \frac{17}{\sqrt{30}}[/tex]
Distribution of the difference of mean grades of boys and girls:
[tex]\mu = \mu_B - \mu_G = 75 - 85 = -10[/tex]
[tex]s = \sqrt{s_B^2+s_G^2} = \sqrt{(\frac{25}{\sqrt{45}})^2+(\frac{17}{\sqrt{30}})^2} = 4.85[/tex]
Confidence interval:
As stated, the critical value is [tex]z = 1.645[/tex]
The margin of error is of:
[tex]M = zs = 1.645*4.85 = 7.98[/tex]
Lower bound:
[tex]\mu - M = -10 - 7.98 = -17.98[/tex]
Upper bound:
[tex]\mu + M = -10 + 7.98 = -2.02[/tex]
The 90% confidence interval for the difference of the population means is approximately (-17.98, -2.02).

Answer:
32
Step-by-step explanation:
Remember angles in a triangle add up to equal 180 degrees
This means that x + 126 + 22 must equal 180
126 + 22 = 148
x + 148 = 180
subtract 148 from each side
148 - 148 cancels out
180 - 148 = 32
we're left with x = 32
Answer:
32 is the answer of above questions.
The perimeter of the figure below is 152.6 ft. Find the length of the missing side.
Answers
Answer:
13.4
Step-by-step explanation:
13.4 is the answer because a perimeter is the total distance around the shape
when you take 152.6 and subtract all of the different sides your left with the length of the last side
152.6 - 13.1 - 13.1 - 9.3 - 54.2 - 9.3 - 27.1 - 13.1 = 13.4

An 18 in long rebar is driven into the ground until it touches an underground pipe. A backsight to a benchmark with an elevation of 393.66 ft is taken with an automatic level. The backsight has a rod reading of 7.56 ft. A foresight is taken to the rod resting on top of the rebar. The rod reading is 1.01 ft. What is the elevation of the top of the pipe
Answers
Answer:
398.71 ft
Step-by-step explanation:
Length of rebar = 18 inches = 1.5 ft
Elevation = 393.66 ft
Reading of backsight on Benchmark= 7.56 ft
Rod reading = 1.10 ft
First step : determine height of Instrument been used
= elevation + backsight on Benchmark
= 393.66 + 7.56 = 401.22 ft
Elevation of top of rebar
= 401.22 - 1.01 = 400.21 ft
Finally determine the elevation of the top of the pipe
= 400.21 - length of Bar
= 400.21 - 1.5 = 398.71 ft
