if you want to be shown step by step comment below
What is the value of x? Enter your answer in the box.
Hello!
We can say that: x = 127°
The sum of the hexagon's internal angles is 720 °. So, just solve an equation:
112 + 133 + 128 + 100 + 120 + x = 720593 + x = 720x = 720 - 593x = 127°So, x = 127°.

Write an equation of the line passing through each of the following pairs of points. b (5, 7), (−6, −3)
Answer:
y = 10/11 x + 2.45
Step-by-step explanation:
Equation of the line
First find the gradient
formula = [tex]\frac{y2-y1}{x2-x1}[/tex]
= [tex]\frac{-3-7}{-6-5}[/tex]
=[tex]\frac{-10}{-11}[/tex]
= 10/11
m is the gradient
equation of a line
y- y1 = m(x-x1)
y-7 = 10/11 (x-5)
y-7 = [tex]\frac{10}{11}x[/tex] - [tex]\frac{50}{11}[/tex]
y = 10/11 x + 2.45
NB i rounded of -50/11 +7 = 2.4545..... to 2.45

What is the answer?
And explain why.
Answer:
7 or any number greater
Step-by-step explanation:
7 plus 7 is greater than or equal to 14. Any number higher than 7 will still be correct, because it will be greater than 14. The little line on the bottom of the symbol means it can be equal to.

Find the area of the triangle
Answer:
472.5 yd²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 30 and h = 31.5 , thus
A = [tex]\frac{1}{2}[/tex] × 30 × 31.5 = 15 × 31.5 = 472.5 yd²

Answer:
Step-by-step explanation:
each box has 12 melon for 15 dollars:
the price of one melon : 15/12=1.25 dollar each
he bought 12 boxes of melon and paid 15 dollars for each :
12*15=180 dollars
total melon is : 12*12=144 dollars
he sold 3/4 of a melon : 3/4 *144=108
the cost of 108 : 108*1.25= 135 dollars
at a price of $ 1.6 = 108*1.6= 172.8
the rest of the melon sold at reduce price=
144-108= 36
over all profit = 15 %
180*(1+0.15)=207 dollars profit
selling 108 melons : $172.8
overall profit - profit from selling 108 melons: 207-172.8=$34.2
reduced price = 34.2/36=0.95 dollarsTela bought a backpack for $34.99 and 3 notebooks for $1.89 each. What is the total price, including a 8% sales tax?
O $41.87
0 $40.66
O $38.77
0 $43.91
Answer:
It would be $43.91
Step-by-step explanation:
It would be $43.91 because if Tela bought a backpack for $34.99 and then bought 3 notebooks that each costed $1.89 then multiplying 8% tax you get the answer of $43.91.

A group of 33 people attended a ball game. There were twice as many children as adults in the
group. Set up a system of equations that represents the numbers of adults and children who
attended the game and solve the system to find the number of adults and the number of children
who were in the group.
Answer: children = 22
Adult = 11
Step-by-step explanation:
Let the number of adult be a
Since there were twice as many children as adults in the
group, the children can be represented by : 2 × a = 2a
We are further told that the group of 33 people attended a ball game. This means that :
adult + children = 33
a + 2a = 33
3a = 33
a = 11
11 adults are in the group
Since 11 adults are in the group, the number of children will be:
= 33 - 11
= 22

According to a random sample taken at 12 A.M., body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.1398.13degrees°F and a standard deviation of 0.620.62degrees°F. Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 33 standard deviations of the mean? What are the minimum and maximum possible body temperatures that are within 33 standard deviations of the mean?
Complete Question
According to a random sample taken at 12 A.M., body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.13degrees°F and a standard deviation of 0.62degrees°F. Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 3 standard deviations of the mean?
What are the minimum and maximum possible body temperatures that are within 3 standard deviations of the mean?
Answer:
a) what do we know about the percentage of healthy adults with body temperatures that are within 3 standard deviations of the mean?
This means that at least 88.89% of healthy adults with body temperatures that are within 3 standard deviations of the mean.
b).What are the minimum and maximum possible body temperatures that are within 3 standard deviations of the mean?
The minimum body temperature within 3 standard deviations of the mean = 96.27°F
The maximum body temperature within 3 standard deviations of the mean = 99.99°F
Step-by-step explanation:
We solve this question using Chebyshev's theorem.
Chebyshev's theorem states that:
1) At least 3/4 of the data lies within two standard deviations of the mean. This means, the interval endpoints :
Mean ± 2Standard deviation
2) At least 8/9 of the data lies within three standard deviations of the mean. This means, the interval endpoints :
Mean ± 3Standard deviation
From the above question,
Mean = 98.13°F
Standard deviation = 0.62°F
The question specified 3 Standard deviation from the mean. Hence,
a) At least 8/9 of the data lies within three standard deviations of the mean. This means, the interval endpoints :
Mean ± 3Standard deviation
Converting this to percentage
8/9 × 100 = 88.89%
Therefore, this means that at least 88.89% of healthy adults with body temperatures that are within 3 standard deviations of the mean.
b) For question B,to find the minimum, maximum value
At least 8/9 of the data lies within three standard deviations of the mean. This means, the interval endpoints :
Mean ± 3Standard deviation
Mean = 98.13°F
Standard deviation = 0.62°F
98.13 - 3 × 0.62
= 96.27°F
98.13 + 3 × 0.62
= 99.99°F
Therefore, the minimum body temperature within 3 standard deviations of the mean = 96.27°F
The maximum body temperature within 3 standard deviations of the mean = 99.99°F
