Answer:
50
Step-by-step explanation:
lxb=144
16xb=144
b=9
perimeter=2(l+b)
=2(16+9)
=50 cm
Answer: 50cm squared
Step-by-step explanation:
First we need to find the side lengths,
In order to find the area you do,
A = Length x height
we know that the area is 144 and the length is 16.
144=16 x height
144 = 16 x ?
So know we need to find the height, so we do 144/16= 9
so the height 9 cm.
The question is not asking for the height, but the peremeter.
Peremeter = (Length x 2) + (height x 2)
peremeter= 16 x 2 + 9 x 2
peremeter = 32+18
peremeter = 50 cm squared
so the peremeter is 50 cm squared.

Solve the equation 1/4(16+12x) =28 by first using the distributive property
Answer: x=8
Step-by-step explanation:
Answer:
The equivalent equation is found by distributing the 1/4 to get 4 + 3x = 28
The first step is subtract 4 to both sides.
The second step is divide both sides by 3.
The answer is x = 8

Using traditional methods, it takes 94 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 40 students and observed that they had a mean of 95 hours. Assume the standard deviation is known to be 3. A level of significance of 0.02 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic
Answer: the value of the test statistic is 2.11
Step-by-step explanation:
Given that;
sample mean x" = 95
standard deviation σ = 3
sample size n = 40
Null hypothesis H₀ : μ = 94
Alternative hypothesis H₁ : μ ≠ 94
Level of significance ∝ = 0.02
Test statistic value
z = (x" - μ) / ( σ/√n)
we substitute
z = (95 - 94) / ( 3/√40)
z = 1 / 0.4743
z = 2.11
Therefore, the value of the test statistic is 2.11

taki has her back to a wall. She starts to walk straight forward. She stops and turns 157° to the right and walks back in this direction until she reaches the wall. What is the angle x that her body is making with the wall.
Answer:
[tex]67^\circ[/tex]
Step-by-step explanation:
Given that:
Initially, Taki has her back to a wall and then starts walking straight forward.
Kindly refer to the diagram attached in the answer area.
Initially, Taki was at point A and then moves towards point B.
At point B, Taki turns [tex]157^\circ[/tex] and then starts walking to reach point C at the wall.
To find:
The angle [tex]x[/tex] that her body is making with the wall.
Solution:
As per question statement:
[tex]M\angle B = 157^\circ[/tex]
We know that angle on straight line is always [tex]180^\circ[/tex]
i.e.
[tex]M\angle B + m\angle B= 180^\circ\\\Rightarrow 157^\circ + m\angle B= 180^\circ\\\Rightarrow m\angle B = 180-157\\\Rightarrow m\angle B = 23^\circ[/tex]
Now, using the angle sum property of a triangle in [tex]\triangle ABC[/tex]:
[tex]m\angle A + m\angle B+ m\angle C = 180^\circ\\\Rightarrow 90+23+x = 180^\circ\\\Rightarrow x = 180 - 90 - 23\\\Rightarrow x = \bold{67^\circ}[/tex]
So, our answer is: [tex]67^\circ[/tex]
A recent report indicated that 22 percent of the households in a certain community speak a
language other than English at home. A reporter will randomly select a household from the
community until the first houehold that speaks a language other than English at home is
selected. Let random variable Q represent the number of attempts needed until the first
household that speaks a language other than English at home is selected. The random variable
Q has a geometric distribution with p = 0.22. Which of the following is closest to the variance
of the random variable?
Answer:
16.1157
Step-by-step explanation:
The random variable Q has a geometric distribution with p = 0.22. The variance of the random variable will be 16.1157.
What is the variance of the random variable?A spread measure for a random variable distribution quantifies how much the values of a random variable deviate from the value that is predicted.
For a discrete random variable, the variance is determined by adding the square of the difference between the value of the random variable and the anticipated value, together with the chance that the value of the random variable will occur, across all of the values of the random variable.
It is given that 22 percent of people in the community speak a language other than English at home.
The required number of tries should be represented by the random variable Q.
The geometric distribution of the random variable Q has a p-value of 0.22.
The variance of a random variable is
V(Q) = (1-p)/p²
V(Q) = (1-0.22)/(0.22)²
V(Q) =0.78/0.484
V(Q) =16.1157
Thus, the random variable Q has a geometric distribution with p = 0.22. The variance of the random variable will be 16.1157.
