Answer:
The height of Roger is 158cm
Step-by-step explanation:
All of them=158cm
They are 4.So,158^4=632cm
Height of 3 persons=155cm+158cm+161cm=474cm
Therefore the height of Roger is 632cm-474cm=158cm
The height of Roger with the mean of all of them is given is 158 cm.
Given that, the heights of Karina, Miya and Clint were 155cm, 158cm, and 161cm respectively.
What is mean?In statistics, the mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations).
Let the height of Roger be R.
Mean= 158 cm
We know that, mean =Sum of all the observations/Number of observations
⇒ (155+158+161+R)/4 =158
⇒ 474+R=632
⇒ R=632-474
⇒ R=158 cm
Hence, the height of Roger with the mean of all of them is given is 158 cm.

The mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet. Let X be the height of a randomly selected adult giraffe. Round all answers to 4 decimal places where possible.
c. What is the Z-score for a giraffe that is 18.5 foot tall?
d. What is the probability that a randomly selected giraffe will be shorter than 17.5 feet tall?
e. What is the probability that a randomly selected giraffe will be between 16.7 and 17.2 feet tall?
f. The 70th percentile for the height of giraffes is ___ ft.
Answer:
Median =17
Step-by-step explanation:
Given that the mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet. Let X be the height of a randomly selected adult giraffe. X is a random variable.
a) X is N(17, 0.9)
b) Median giraffe height = 17 ft since in normal distribution mean = median
c) When x = 18.5, Z = 18.5-17/0.9 = Z= 0.1667
d) P( x < 18) = P( Z < 56)
= 0. 2877
e) P(16.9 < x < 17.9) = P(-0.11 < z < 1) = .0.438 + 0.3413
= 0.3851
f) 75th percentile for z is 0.675
x = 17.9 + 0.9 (0.675)
= 18.5075

If six angles of a heptagon have measures of 122, 153, 168, 105, 162, and 87, what is the measure of the seventh angle?
Answer:
he seventh angles measure is 103
Step-by-step explanation:
Interior angles = (number of side in the polygon - 2) times 180.
So Heptagon interior angles = (7-2)(180) = 900
To find the missing angles add all the given angles together (122, 153, 168, 105, 162, and 87) = 797.
Now The measure of the seventh angles = total angles measure - the six given angles,
The seventh angles measure is 103
900 - 797 = 103
Enter the value of x. The diagram is not to scale.

what is [tex]−3.64⋅|5.3|−1.5^3[/tex]
Answer:
- 22.667
Step-by-step explanation:
1.5^3 = 1.5 x 1.5 x 1.5 = 3.375
- 3.64 ⋅ | 5.3 | - 1.5^3
= ( - 3.64 ⋅ | 5.3 | ) - 1.5^3
= ( - 3.64 ⋅ 5.3 ) - 1.5^3
= ( - 3.64 x 5.3 ) - 1.5^3
= - 19.292 - 3.375
= - 22.667

Answer:
x ≤ -12
Step-by-step explanation:
to solve for 'x', since it is getting multiplied by 1/4, you must multiply it by the inverse which is 4
whatever gets multiplied to one side of the inequality must also get multiplied to the other side
you will get:
x ≤ -12

A factory makes 84 toys robots in a day after they purchase new equipment now they make 205 robots a day
Based on the given information the percent gain is 144%.
Initial production rate = 84 toy robots per day
Present production rate = 205 robots per day
Using this formula
Percent gain= Increase in production rate /Initial production rate× 100
Where:
Increase in production rate = 205 - 84 =121
Initial production rate = 84 toy robots per day
Let plug in the formula
Percent gain=121/84×100
Percent gain=144%
Inconclusion the percent gain is 144%.

How do you compare exponential functions??
I really don't understand, also giving brainliest!!
Answer:
You compare it by this
Step-by-step explanation:
Linear functions are graphed as straight lines while exponential functions are curved. Linear functions are typically in the form y = mx + b, which is used to discover the slope, or simply the change in y divided by the change in x, while exponential functions are typically in the form y = (1 + r) x.

Solve For x for the remaining problems. You MUST show your work.
Answer:
x = 6
Step-by-step explanation:
All angles of a triangle equal 180
180 - 70 - 60 = 50
8x+2 = 50
x = 6
Answer:
x = 6
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
70 + 60 + 8x + 2 = 180 , collect like terms
132 + 8x = 180 ( subtract 132 from both sides )
8x = 48 ( divide both sides by 8 )
x = 6
write the equation of the line from the given information (-2,4) & (-3,5)
Step 1: Find the slope
Slope Formula = (y2 - y1) / (x2 - x1)
Point 1 = (-2, 4)
Point 2 = (-3, 5)
slope = (5 - 4) / (-3 - - 2) = (5 - 4) / (-3 + 2) = (1) / (-1) = -1
Step 2: Find the y-intercept
To find the y-intercept, we will take one of the given points as well as the slope and plug them into slope-intercept form. Then, we will solve for b.
Slope-Intercept Form: y = mx + b
Point = (-2, 4)
Slope = -1
4 = -1(2) + b
4 = -2 + b
b = 6
Step 3: Put it all together
Now that we have the slope and the y-intercept, all that's left to do is plug it into slope-intercept form.
Slope-Intercept Form: y = mx + b
Slope = -1
Y-Intercept = 6
y = -x + 6
