Two circles have a scale factor of 3:2. What is the ratio of the circumferences of these circles?
A. 12:26
B. 13:12
C. 9:4
D. 3:2
Answer:
3:2
Step-by-step explanation:
The circumference is a distance. The ratio of the distance is the same as the scale factor. The ratio of the areas is the ratio of the scale factor squared and the volume is the scale factor cubed.
The class average on a math test was an 82 with a standard deviation of 5. If the
data is normally distributed, which statements are true?
1. A student scoring a 74 would have a z -score of -1.6.
2. About 68% of the students scored below an 87.
3. A z-score of 2.6 would be a test
score of 95.
4. About 16% of the class scored a 77 or below.
45. About 25% of the class scored above a 92.
Answer:
Option 3 and 4.
Step-by-step explanation:
The z score shows by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean, \ \sigma=standard\ deviation[/tex]
Given that mean (μ) = 82, standard deviation (σ) = 5
1) For x = 74:
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{74-82}{5} =-1.6[/tex]
Option 1 is incorrect
2) For x < 87
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{87-82}{5} =1[/tex]
From the normal distribution table, P(x < 87) = P(z < 1) = 0.8413 = 84.13%
Option 2 is incorrect
3) For x = 95:
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{95-82}{5} =2.6[/tex]
Option 3 is correct
4) For x < 77
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{77-82}{5} =-1[/tex]
From the normal distribution table, P(x < 77) = P(z < -1) = 0.16 = 16%
Option 4 is correct
5) For x > 92
[tex]z=\frac{x-\mu}{\sigma} \\\\z=\frac{92-82}{5} =2[/tex]
From the normal distribution table, P(x > 92) = P(z > 2) = 1 - P(z < -2) = 1 - 0.9772 = 0.0228 = 2.28%
Option 5 is incorrect

Solve the system of equations
Answer:
(3,5)
Step-by-step explanation:
For this equation, you need to solve it like simultaneous equations. Both of these have a 4y, so that is relatively easy to do, once you know how to.
The signs in front of the 4y are different, so you add the 2 equations (to remove the ys all together).
This should be (2x+-8x)+(-4y+4y)=(-14+-4), or (2x-8x)+(4y-4y)=(-14-4).
This can be expanded to -6x+0=-18, or -6x=-18.
Dividing both sides by -6 leaves you with x=3.
To find y, substitute this x value into either equation (I picked equation 1 as it is simpler). This gives you 2(3)-4y=-14, expanded to 6-4y=-14.
From there, you subtract the 6 from both sides, to get the y alone (giving -4y=-20).
By dividing both sides by -4, you get y=5.
This means the answer is (3,5).
**This question involves simultaneous equations, so you might want to look at that. I'm always happy to help!

Luis's bowling scores were 195, 194, 191, 190, 238, and 192. Which measure (median, mean, mode or range) BEST describes Luis's bowling score? EXPLAIN your answer.
Step-by-step explanation:
The given data is :
195, 194, 191, 190, 238, and 192
Mean = (sum of observations)/(total no. of observations)
[tex]\text{Mean}=\dfrac{195+194+191+190+238+192}{6}\\\\=200[/tex]
So, the mean is the best measure. Also, w can find median as follows.
arranging in order : 190,191,192, 194, 195,238
Here, n = 6
[tex]\text{Median}=\dfrac{\dfrac{n}{2}^{th}+(\dfrac{n}{2}+1)^{th}}{2}\\\\\text{Median}=\dfrac{\dfrac{6}{2}^{th}+(\dfrac{6}{2}+1)^{th}}{2}\\\\=\dfrac{3^{th}+4^{th}}{2}\\\\=\dfrac{192+194}{2}\\\\=193[/tex]
Hence, this is the required solution

Carly is buying deli meat for her lunches this week. Turkey is on sale for $5.80 per pound. If Carly buys 1.25 pounds of turkey, how much money does she spend?
Answer:
Carly will have to spend $7.25
Step-by-step explanation:
We know that:
1 pound of turkey = $5.80
To find how much 1.25 pounds of turkey will cost, multiply:
5.80 x 1.25 = 7.25
Therefore, 1.25 pounds of turkey will cost $7.25

Which set of numbers can represent the side lengths, in inches, of an acute triangle? 4, 5, 7 5, 7, 8 6, 7, 10 7, 9, 12 Which set of numbers can represent the side lengths, in centimeters, of a right triangle? 8, 12, 15 10, 24, 26 12, 20, 25 15, 18, 20
Answer:
1) 5, 7, 8
2) 10, 24, 26
Step-by-step explanation:
1) For an acute triangle, the square of the longest side is less than the sum of the square of the two smaller sides.
a) 4² + 5² = 16 + 25 = 41
7² = 49 > 4² + 5². Therefore the triangle is not acute
b) 5² + 7² = 25 + 49 = 74
8² = 64 < 5² + 7². Therefore the triangle is acute
c) 6² + 7² = 36 + 49 = 85
10² = 100 > 6² + 7². Therefore the triangle is not acute
d) 7² + 9² = 49 + 81 = 130
12² = 144 > 7² + 9². Therefore the triangle is not acute
2) For a right angled triangle, the square of the longest side is equal to the sum of the square of the two smaller sides.
a) 8² + 12² = 64 + 144 = 208
15² = 225 > 8² + 12². Therefore the triangle is not a right triangle.
b) 10² + 24² = 100 + 576 = 676
26² = 676 = 10² + 24². Therefore the triangle is a right triangle.
c) 20² + 12² = 400 + 144 = 544
25² = 625 > 20² + 12². Therefore the triangle is not a right triangle.
d) 15² + 18² = 225 + 324 = 549
20² = 400 < 15² + 18². Therefore the triangle is not a right triangle.

Find the slope of the in line containing the ordered pairs. (7 marks)
a. A(2,-5), B(-2,6)
Answer:
= -11/4
Step-by-step explanation:
To find the slope given two points
m = ( y2-y1)/(x2-x1)
= (6 - -5)/(-2 -2)
= (6+5)/(-2-2)
= 11/-4
= -11/4
Answer:
-2.75 (-2 3/4)
Step-by-step explanation:
you can do rise of a run whenever you have two points so you have 6-(-5)/-2-2 and solve so -11/4 and that equals -2.75.
