Answer:
x = 3.5; perimeter = 59; area = 8
Step-by-step explanation:
isosceles means the two legs equal each other so use same expression later on
6x + 8 = 2x - 6
6x - 2x = -8 - 6
4x = -14
x = 3.5
plug x value in the first expression to find the two sides that are equivalent to each other
6(3.5) + 8
21 + 8
29
plug x value into the second expression (the base)
2(3.5) - 6
7 - 6
1
perimeter = side 1 + side 2 + side 3
perimeter = 29 + 29 + 1
perimeter = 59
area = base × height/2 or bh/2
first plug in x value into height expression
4x + 2
4(3.5) + 2
14 + 2
16
area = 1 × 16/2
area = 16/2
area = 8

The number of meters a student swam this week are listed.
200, 450, 600, 650, 700, 800
What is the appropriate measure of variability for the data shown, and what is its value?
The range is the best measure of variability and equals 600.
The IQR is the best measure of variability and equals 250.
The mean is the best measure of variability and equals about 567.
The median is the best measure of variability and equals 625.
Answer:
Step-by-step explanation:
800 - 200 = 600 = range
Inter Quartile Range is hard to measure.
566 2/3 = mean = close enough to 567

The average number of claims per hour made to an insurance company is 3.
a. What is the probability that over the next hour 4 claims will be placed?
b. What is the probability that over the next 3 hours 6 claims will be placed?
Step-by-step explanation:
We have it that x follows a poisson distribution.
λ is equal to 3
The poisson distribution is given by:
P(x) = e^-λ * λ^X/X!
λ = 3
X = 4
A. The question had already given us the X value to be 4
p(x = 4)
= e^-3 x 3⁴/4!
= e^-3 = 0.001
3⁴= 34
4! = 81
putting all values into p(x=4)
= .001x81/24
= 0.1680
b. for 3 good hours, we will have lamda to be;
3x3 = 9
p(x = 6)
= e^-9 * 9⁶/6!
= 0.0911
point S is located at -1 on the number. point T is located at 6 on the number line What is the distance between point s and point t on the number lines?
The Distance between point S and point T on the number line is 7 units. The units could be inches, centimeters, meters, or any other unit of measurement depending on the scale of the number line that is being used
The number line is a geometric representation of the actual number system. It can be a great aid in visualizing math problems. When we use a number line to locate two points, it helps us to determine the distance between them, as well as to measure the magnitude of the numbers.
We can also use the number line to help us add and subtract values. Now, to find the distance between point S and point T on the number line, we can use the following formula:
Distance between two points = Absolute value of (coordinate of point T - coordinate of point S)In our given problem, we are given that point S is located at -1 on the number line and point T is located at 6 on the number line. We can plug these values into the formula:
Distance between two points = Absolute value of (6 - (-1)) = Absolute value of (6 + 1) = Absolute value of 7 = 7 units
Therefore, the distance between point S and point T on the number line is 7 units. The units could be inches, centimeters, meters, or any other unit of measurement depending on the scale of the number line that is being used.

Solving the equation
Answer:
-1
Step-by-step explanation:
We need to isolate x.
When we do so, we want it to be a positive term.
-x = 28
To get the x term positive, we divide both sides by -1.
x = -28
Answer:
[tex]\huge\boxed{-1}[/tex]
Step-by-step explanation:
In order to solve an equation, our goal is to isolate the variable on one side of the equation.
As of now, we have [tex]-x = 28[/tex]
This is the exact same thing as [tex]-1x = 28[/tex], since a negative sign also means you multiply it by -1.
We want to divide both sides by the coefficient on x so that we have x, positive and isolated, on one side of the equation.
Therefore we want to divide by -1.

Simplify x^2×(x^3÷x^-2/x^2÷x^-3)
Answer:
x^8
Step-by-step explanation:
Simplify the following:
(x^2 x^3)/(x^(-2) x^2 x^(-3))
Multiply the numerator of (x^3)/((x^2)/(x^2) x^(-3)) by the reciprocal of the denominator. (x^3)/((x^2)/(x^2) x^(-3)) = (x^3 x^3)/((x^2)/(x^2)):
x^2 (x^3 x^3)/((x^2)/(x^2))
(x^3 x^3 x^2)/((x^2)/(x^2)) = x^2/x^2×(x^3 x^3)/x^(-2) = (x^3 x^3)/x^(-2):
(x^3 x^3)/x^(-2)
Combine powers. (x^3 x^3)/x^(-2) = x^(3 + 3 + 2):
x^(3 + 3 + 2)

What is the slope of this line
Answer:
[tex]\boxed {m = \frac{3}{2}}[/tex]
Step-by-step explanation:
To determine the slope of the following line shown on the graph, you need to use the Slope Formula:
[tex]m = \frac{y_{2}- y_{1}}{x_{2} - x_{1}}[/tex]
(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)
-The points I found on the graph are [tex](-3, -3)[/tex] and [tex](-1, 0)[/tex]. Then, apply them onto the formula:
[tex](x_{1}, y_{1}) = (-3, -3)[/tex]
[tex](x_{2}, y_{2}) = (-1, 0)[/tex]
[tex]m = \frac{-3 - 0}{-3 + 1}[/tex]
-Solve:
[tex]m = \frac{-3 - 0}{-3 + 1}[/tex]
[tex]\boxed {m = \frac{3}{2}}[/tex]
Therefore, the slope is [tex]\frac{3}{2}[/tex].

A graph is shown with x and y axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 5, 0. Another straight line labeled B joins the ordered pair 0, 2 with the ordered pair 6, 6.
Based on the graph, which statement is correct about the solution to the system of equations for lines A and B?
(3, 4) is the solution to both lines A and B.
(3, 4) is the solution to line A but not to line B.

A farmer is traveling down a trail with his dog (who is always hungry), two geese (who are also
always hungry), and three bags of grain. Soon, the trail leads into a river but begins again on
the other side. To get to the other side the farmer must wade across the river yet he can only
carry two of his six possessions at a time. The farmer knows that, if left together, the dog will
eat any or all of the geese and any of the geese will eat all the grain they can. How can the
farmer get all of his possessions to the other side of the river safely and uneaten?
Answer:
Carry the grain first, then his dog.
Step-by-step explanation:
The geese are geese. They can swim.
The Smelting Department of Kiner Company has the following production and cost data for November. Production: Beginning work in process 2,000 units that are 100% complete as to materials and 20% complete as to conversion costs; units transferred out 9,000 units; and ending work in process 7,000 units that are 100% complete as to materials and 40% complete as to conversion costs. Compute the equivalent units of production for (a) materials and (b) conversion costs for the month of November.
Answer:
a. 16000 units
b. 11800 units
Step-by-step explanation:
A.
To get equivalent units of production for materials
Add up the units transferred out + ending work in progress
= 9000 units + 7000 units
= 16000 units
B.
To get conversion cost for November:
Units that are transferred out + (ending work in progress * % of conversion)
= 9000 + (7000 x 40%)
= 9000 + 2800
= 11800 units
The answers are therefore
1. 16000units
2. 11800 units
In an annual report to investors, an investment firm claims that the share price of one of their bond funds had very little variability. The report shows the average price as $18.00 with a variance of 0.11. One of the investors wants to investigate this claim. He takes a random sample of the share prices for 10 days throughout the last year and finds that the standard deviation of the share price is 0.1448. Can the investor conclude that the variance of the share price of the bond fund is different than claimed at α=0.1? Assume the population is normally distributed.

A ball is thrown upward with an initial velocity of 60 mph. it is thrown from a height of 5 feet. what is the maximum height it reaches?
Answer:
h = 61.25 m
Step-by-step explanation:
It is given that,
The initial velocity of the ball, v = 60 m/s
It is thrown from a height of 5 feet, [tex]h_o=5\ ft[/tex]
We need to find the maximum height it reaches. The height reached by the projectile as a function of time t is given by :
[tex]h=-16t^2+vt+h_0[/tex]
Putting all the values,
[tex]h=-16t^2+60t+5[/tex] .....(1)
For maximum height, put
[tex]\dfrac{dh}{dt}=0\\\\\dfrac{-16t^2+60t+5}{dt}=0\\\\-32t+60=0\\\\t=\dfrac{-60}{-32}\\\\t=1.875\ s[/tex]
Put t = 1.875 in equation (1)
[tex]h=-16(1.875)^2+60(1.875)+5\\\\h=61.25\ m[/tex]
So, the maximum height reached by the ball is 61.25 m.
