Answer:
a = 38
b = 54
c = b = 54
Step-by-step explanation:
[tex] a + 142 = 180\\ a = 180 - 142 = 38 \\ 88 + 38 + b = 180 \\ b = 180 - 126 = 54 \\ c = b = 54[/tex]

From the above expression we get,
=》x + y = 7 - [1]
=》3x - 2y = 11 - [2]
now, let's solve :
multiplying [1] by 3
=》3x + 3y = 21
=》 3x - 2y = 11
subtracting
now, subtracting [2] from [1]
=》3x + 3y - 3x + 2y = 21 - 11
=》5y = 10
=》y = 2
now, plugging the value of y as 2 in equation [1]
=》x + y = 7
=》x + 2 = 7
=》x = 5
So, value of :
x = 5y = 2Factor to write an equivalent expression using the GCF.

You randomly select three marbles from jar that contains 23 black
marbles, 32 blue marbles and 8 white marbles.
What is the probability that the first marble is blue, the second marble
is black and the last marble is not blue if you do not replace the first
and second marbles? Enter your answer as a decimal rounded to the
nearest thousandth.
Marble, blue marble first time, red marbles second time, white marble
Answer: 0.093 chance
Step-by-step explanation:
23 black + 32 blue + 8 white = 63 total
FIRST MARBLE IS BLUE:
32/63
SECOND MARBLE IS BLACK:
23/62
LAST MARBLE IS NOT BLUE:
30/61
MATH:
32/63*23/62*31/61 = 0.093
sorry if it’s wrong but I think it’s right
Answer:
.093
Step-by-step explanation:
There are 63 marbles in the jar
P(pick a blue) = 32/63
Since you are not replacing that marble, so there are 62 marbles in the jar, 31 blue, 23 black, 8 white
P(pick a black) = 23/62
Now there are 61 marbles in the jar. 22 black, 31 blue and 8 white
P(not a blue) = 30/61
P(blue, black, not blue) = (32/63)(23/62)(30/61)
= .093

[tex]\lim_{x \to 0} \frac{\sqrt{x+5}-\sqrt{5} }{x} =\frac{\sqrt{5}}{10}[/tex]
Step-by-step explanation:
If x=-0.1, then f(x)=0.2247361538
If x=-0.01, then f(x)=0.2237187131
If x=-0.001, then f(x)=0.2236179792
If x=0.001, then f(x)=0.2235956185
If x=0.01, then f(x)=0.223495106
If x=0.1, then f(x)=0.2224998063
We can see that as x approaches 0, we see that f(x) gets closer to √5/10
Therefore, [tex]\lim_{x \to 0} \frac{\sqrt{x+5}-\sqrt{5} }{x} =\frac{\sqrt{5}}{10}[/tex]

Solve for x for the linear pairs.
Answer:
X = 13
Step-by-step explanation:
Since this is a linear pair, it equals to 180 degrees.
7x + 37 + 4x = 180
11x + 37 = 180
-37 -37
11x = 143
11x/11 = 143/11
x = 13

An earring has the shape of a rhombus. The height is 5.2 mm and the
area of the earring is 39 mm2. What is the length of each side of
the earring?
9514 1404 393
Answer:
7.5 mm
Step-by-step explanation:
As with any parallelogram, the area of a rhombus is given by ...
A = bh
Using the given values, we find ...
39 mm² = b(5.2 mm)
b = (39 mm²)/(5.2 mm) = 7.5 mm
The length of each side is 7.5 mm.
Answer:
Solution given:
height=5.2mm
Area of rhombus=39mm²
we have
Area of rhombus=base*height
39=5.2×base
base=39/5.2
base=7.5mm
the length of each side of
the length of each side ofthe earring is 7.5mm.

A sample of 144 was taken from a population with a standard deviation of 36
inches. What is the margin of error for a 68% confidence interval?
A. 9
B. 6
C. 3
D. 12
Answer:
9 inches
Step-by-step explanation:
The population is within 6 standard deviations of the mean with a confidence of 99.7 percent, 3 above and 3 below
The standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size
population standard deviation = 36
sample size = 144
standard deviation of the sample mean = 36/ sqrt(144)
=36/12
=3
The margin of error is the number of standard deviations above the mean * the standard deviations
margin of error = 3 * 3
= 9 inches
Find the mean, median, and mode(s) of the data with and without the outlier.
45, 52, 17, 63, 57, 42, 54, 58
Answer:
Mean = 48.5, Median = 53, Mode = nothing, Outlier = 17
Step-by-step explanation:
Mean: Add all the numbers (388) then divide by how many numbers (8) are there. (= 48.5)
Median: Is the middle number () so you have to order them from least to greatest (17, 42, 45, 52, 54, 57, 58, 63) and then just keep marking them off left, right, left, right... until you get to the middle. But since there are two numbers (52, 54) you have to add them (106) then you divide by 2 (53).
Mode: Is the number that shows up the most. In this case none of them do.
Outlier: The number that is farthest from the other numbers (17).
The mean, median, and mode(s) of the data Without outlier Mean is 51
Median is 53 and Mode is None
To find the mean, median, and mode(s) of the data, we can start by arranging the numbers in order from smallest to largest:
17, 42, 45, 52, 54, 57, 58, 63
The mean is the sum of all the numbers divided by the total number of numbers.
If we remove the outlier (17), the data set becomes:
42, 45, 52, 54, 57, 58, 63
Mean:
Mean = (42 + 45 + 52 + 54 + 57 + 58 + 63) / 7 = 51
Median:
Median = (52 + 54) / 2 = 53
There is no mode in this set since no number appears more than once.
