Step-by-step explanation:
a) 147
b)147
c) 152
d)65
Answer:
a) mean = 147
b) median = 147
c) mode = 152
d) range = 65
Step-by-step explanation:
firsly let’s arrange the numbers of the set in ascending order:
117 , 119 , 138 , 142 , 152 , 152 , 174 , 182
a)
[tex]Mean = \frac{117+119+138+142+152+152+174+182}{8} =\frac{1176}{8} =147[/tex]
b) the median is the average of the two middle numbers :
[tex]117,119,138, \frac{142,152}{} , 152,174,182[/tex]
[tex]median=\frac{142+152}{2}= 147[/tex]
c) the modal height is 152 because 152 is the value that appears most frequently (2 times) in our set
d) the range of a set is the difference between the highest and lowest numbers :
Then
the range = 182-117 = 65

Step-by-step explanation:
median -> $24.710+$25.180=$49.89
$49.98÷2=$24.945
mode -> $25.520 and $24.710

The price of a pack of kitchen rolls is reduced by
1/6
The new price is £1.20
Work out the original price.
Answers
Answer: 1.44
Step-by-step explanation: 1.20 Is the remaining 5/6 which is 83.3%
Calculate for 100% to get actual amount
If 83.3% = 1.20
1% = 1.20/83.3
100% = 1.20/83.3 ×100/1
The original price is equal to £7.2
What are the cost price and selling price?1. Cost price = Selling price − profit ( when selling price and profit are given )
2. Cost price = Selling price + loss ( when selling price and loss are given )
Given here: New price =£ 1.20
let the original price be x then we have
x/6 = 1.20
x=£7.2
Hence, The original price is £7.2

find the angle between unit vector I and a=√3i+j
Answers
Recall that for two vectors x and y,
x • y = ||x|| ||y|| cos(θ)
where θ is the angle between them.
We have
i • (√3 i + j) = √3
||i|| = 1
||√3 i + j|| = √((√3)² + 1²) = √4 = 2
Solve for θ :
√3 = 2 cos(θ)
cos(θ) = √3/2
θ = arccos(√3/2) = π/6
(Note that we assume θ is the acute angle between the vectors.)
what is the area of a 14cm square?
Answers
Answer:
The area would be 196 cm or 1.96 meters.
Step-by-step explanation:
Since it is a square, all of the sides are the same length.
So we do 14*14 to find the area.
14*14 = 196
So the answer is 196 cm or 1.96 meters.

The tangent or tanθ function of trigonometry is the ratio of its perpendicular to its base in a right triangle. The total height of the sky scrapper is 118.25 meters.
What is Tangent (Tanθ)?The tangent or tanθ function of trigonometry is the ratio of its perpendicular to its base in a right triangle. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
Since the horizontal distance between Hannah's eyes and the sky scrapper is 194 meters while the angle between the eye and the top of the sky scrapper is 31°. Therefore, the vertical height of the sky scrapper from the height of Hannah's eye level, using the tangent function can be written as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\\\\\\tan(31^o) = \dfrac{\text{Height of sky scrapper from eye level}}{194\ meters}\\\\\\\text{Height of sky scrapper from eye level} = 116.567\ meters[/tex]
Since the height of the eye level is 1.68 meters from the ground, therefore, the total height of the sky scrapper can be written as,
[tex]\rm \text{Total height of sky scrapper from ground}\\\\=(\text{Height of sky scrapper from eye level}) + 1.68\ meters\\\\= 116.567 + 1.68\\\\= 118.25\ meters[/tex]
Hence, the total height of the sky scrapper is 118.25 meters.

Given the functions below, find f(2)-g(-7).
Will give brainliest :))
Answers
Answer:
49
There u go :)
Answer:
Given the functions below, f(2) - g(-7) is -34.
Step-by-step explanation:
f(2) - g(-7)
First solve f(2).
f(x) = -|3 - 8x|
Substitute variable.
f(2) = -|3 - 8(2)|
Multiply.
f(2) = -|3 - 16|
Subtract 16 from 3.
f(2) = -|-13|
Apply absolute value.
f(2) = -13
Now solve g(-7).
g(x) = x² + 4x
Substitute variable.
g(-7) = (-7)² + 4(-7)
Raise -7 to the second power.
g(-7) = 49 + 4(-7)
Multiply 4 and -7.
g(-7) = 49 - 28
Subtract 28 from 49.
g(-7) = 21
Now with those values, lets go back to our original equation.
f(2) - g(-7)
Substitute known values.
-13 - 21
Subtract 21 from -13.
-34.

B. What is the probability that a bodybuilder selected at random has a weight greater than 195 pounds?
Answers
Answer:
A. 637
B. 0.2240 (4 dp) = 22.4% (nearest tenth)
Step-by-step explanation:
Normal Distribution
[tex]\sf X \sim N(\mu, \sigma^2)[/tex]
Given:
[tex]\sf \mu = 190.6[/tex][tex]\sf \sigma=5.8[/tex][tex]\implies \sf X \sim N(190.6, 5.8^2)[/tex]
Part A[tex]\begin{aligned}\sf P(180 < X < 190) & = \sf P(X < 190)-P(X\leq 180)\\& = \sf 0.4588035995-0.03380583874\\& = \sf 0.4249977608\end{aligned}[/tex]
Total number of bodybuilders = 1500
Therefore, the number of bodybuilders between 180 and 190 pounds is:
[tex]\begin{aligned}\sf P(180 < X < 190) \cdot1500 & = \sf 0.4249977608 \cdot 1500\\& = \sf 637.4966412\\& = \sf 637\end{aligned}[/tex]
Part B[tex]\begin{aligned}\sf P(X > 195) & = \sf 1-P(X\leq 195)\\& = \sf 1-0.7759602537\\ & = \sf 0.2240397463\\ & = \sf 0.2240\:(4\:dp)\end{aligned}[/tex]

The function f(x) = 2* and g (x) = f(x) + k. If k = 2, what can be concluded about the graph of
g (x)?
Answers
Translations are transformations that change the position of the graph of a function. The general shape of the graph of a function is moved up, down, to the right or to the left. The translations are considered rigid transformations.
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
To graph y = f (x) -k, move the graph of k units down.
We have then:
f (x) = 2 ^ x
g (x) = f (x) + k
if k = 2
then,
the graph of g (x) is shifted vertically 2 units up
Answer:
the graph of g (x) is shifted vertically 2 units up

The area of a triangle is 1/2 base * height.
The base of one side is 13, and the height is 30.
30 * 13 = 390
390 / 2 = 195
Now, there are six of these triangle faces, so multiply that number by six.
195 * 6 = 1170
Now, just add the area of the base:
1170 + 439.1 = 1609.1
