The left side of a solid block is held at a constant temperature of 200°C. The temperature profile within the block is given by T=200−5x−x2 where x is the distance from the left side of the block in centimeters and T is the temperature in degrees Celsius of the block at location x. At what value of x is T=50°C?
Answer:
with T = 50⁰C, we have:
50 = 200 - 5x - x²
<=> x² + 5x = 150
<=> x² + 5x - 150 = 0
=> x = 10

1.Given the information provided for the right triangles shown here, find the unknown leg lengths to the nearest tenth.
2.The triangle shown here is not a right triangle. What are two different ways you change one of the values so it would be a right triangle? Sketch these new right triangles, and clearly label the right angle.
Answer:
1.
For triangle 1
[tex]a = 3\sqrt{5}[/tex]
For triangle 2
[tex]x = 2\sqrt{2}[/tex]
2.
Way 1
By reducing the length of the side 4 to 3.60
Way 2
By increasing the length of side 7 to 7.21
Step-by-step explanation:
The complete question is attached in the image
Solution
1.
Both the triangles are right angled triangle
For triangle 1
[tex]7^2 = 2^2 + a^2\\49 = 4 + a^2\\a^2 = 45\\a = 3\sqrt{5}[/tex]
For triangle 2
[tex]4^2 = x^2+x^2\\2x^2 = 4*4\\x^2 = 8\\x = 2\sqrt{2}[/tex]
2.
Way 1
By reducing the length of the side 4 to 3.60
Way 2
By increasing the length of side 7 to 7.21
If A and B are mutually exclusive, and if P(A) = 23% and P(B) = 16%, what is P(A or B)?
P(A or B)=[%
Answer:
P(A or B) = 39%
Step-by-step explanation:
If A and B are mutually exclusive, they cannot occur at the same time, therefore their probabilities are added. This means P(A or B) = P(A) + P(B) = 23% + 16% = 39%

A χ2 goodness-of-fit test is performed on a random sample of a bag of 30 Skittles® to determine whether the proportion of each flavor (strawberry, orange, lemon, lime, and grape) is equal to the claimed amount (20% of each flavor). The χ2 statistic is determined to be 10.20. What is the p-value for this test? (4 points)
A 0.001 < p < 0.005
B 0.02 < p < 0.025
C 0.025 < p < 0.05
D 0.10 < p < 0.15
E 0.05 < p < 0.10
Answer:
C. 0.025 < p < 0.05
Step-by-step explanation:
The [tex]\chi^2[/tex] goodness-of-fit test parameters are presented here as follows;
The number of Skittles in the bag = 30 Skittles
The different flavors in the bag of Skittles = Strawberry, orange, lemon, lime, and grape
The number of different flavors, n = 5 flavors
The [tex]\chi^2[/tex] statistic = 10.20
Therefore, the degrees of freedom, d.f. = n - 1 = 5 - 1 = 4
Using the chi-square ([tex]\chi^2[/tex]) distribution table, we have;
The probability at 4 degrees of freedom for a [tex]\chi^2[/tex] statistic of 10.20 is between 0.025 and 0.05
Therefore, we get;
The probability (P > 10.20) = 0.025 < p < 0.05.

Find the circumference of a circle with a radius of 100 centimeters.
Answer:
your answer is 628.32cm :)
Answer: I think it is 628.32
Step-by-step explanation: You have to multiply the radius by two to get the diameter and then multiply that by 3.14(PI)
100 x 2=200
3.14 x 200=628.32

charlies goal is to sell an average of 18 cars each month this year. this table shows how many cars he sold each month from january to november. how many cars does charlie need to sell in december in order to meet his goal of a mean of 18 cars per month?
A. 17
B. 19
C. 26
D. 28
Answer: C-26
Step-by-step explanation: First you need to figure out how many total cars he needs to sell through the year by multiplying 12 by 18. This should get you 216. Now, we need to add all of his actual stats that we have so far to get a total of 190 cars sold. We know he needs 216 total by the end of the year, so we just have to subtract 190 from 216 to get our answer, 26.

Jake has a 34% batting average. If Jake gets up to bat 10 times in one game, what is the BEST estimate of how many times he will hit the ball?
Answer:
Approximately 3 times, Jake will be able to hit the ball in a game of 10 balls
Step-by-step explanation:
Batting average determine the % share of time the bat hit the ball.
Jake's probability of hitting a ball = 0.34
Jake plays 10 games.
Probability of hitting a ball in a game is
10 * 0.34 = 3.4
Approximately 3 times, Jake will be able to hit the ball in a game of 10 balls

The area of a square is 50 square meters. Find the length of a side. LABEL answer!!
Answer:
12.5
Step-by-step explanation:
50÷4=12.5
Answer:
≈ 7.07m
Step-by-step explanation:
Let the length of a side of a square
= a metre
a² = 50 m²
[tex] \sf{a = \sqrt{50m {}^{2} }}[/tex]
[tex] \sf{ = \sqrt{2 \times 5 \times 5m {}^{2} }}[/tex]
[tex] \sf{ = 5 \sqrt{2m} }[/tex]
≈ 5x 1.414
≈ 7.07 m
therefore

[tex] \sf \: = 5 \sqrt{2m} [/tex]
7.07midentify the center and radius of the circle (x-7)^2+(y-11)^2=36
Answer:
Centre is [tex](7,11)[/tex]
Radius is [tex]6[/tex]
Step-by-step explanation:
The general equation for a circle is written in the form [tex](x-a)^2+(y-b)^2=r^2[/tex] , where [tex](a,b)[/tex] is the centre of the circle, and [tex]r[/tex] is the radius.
For your circle, [tex](x-7)^2+(y-11)=36[/tex], we can compare it with the general equation to find the centre and radius.
[tex]-a = -7[/tex]
[tex]-b = -11[/tex]
[tex]r^2 = 36[/tex]
Therefore, [tex]a=7[/tex], [tex]b=11[/tex] and [tex]r=6[/tex].
Centre at [tex](a,b)[/tex] which is [tex](7,11)[/tex] .
You are given that 3y = 5x.
a) Find the value of y when x = 12
Answer:
y = 20.
Step-by-step explanation:
Multiply 5 by 12.
Divide both 3y and 60 by 3.
Remove 3 from 3y.
Divide 60 by 3.
The value of y from the given equation when x=12 is 20.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 3y=5x.
The value of y when x= 12 is
3y=5×12
y=5×4
y=20
Therefore, the value of y is 20.

Find the length of side RN
Answer:
RN ≈ 4.2
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos65° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RN}{PR}[/tex] = [tex]\frac{RN}{10}[/tex] ( multiply both sides by 10 )
10 × cos65° = RN , then
RN ≈ 4.2 ( to 1 dec. place )
