Answer:
The width of the Television is 32 inches.
Step-by-step explanation:
It seems as if the hypotenuse of the triangle is 40 inches, and one of the side lengths of it is 24 inches.
a2+b2=c2
So if we square 40 we get 1600, which is c2
If we square 24, we get 576, which is a2.
Then you solve, 576+b2=1600
you get b2=1600
Then you get the square root of both sides which in turn gives you the answer
b=32, which is the width of the television.
Step-by-step explanation:
use the pythagorean theorem c^2 = a^2 + b^2 diagonal is the hypotenuse...
40^2 = 24^2 + b^2
b^2 = 40^2 - 24^2
b =
[tex] b = \sqrt{40 {}^{2} - 24 {}^{2} } [/tex]

Answer:
y = -7/3x + 5
Step-by-step explanation:
7x + 3y = 15

y = -7/3x + 5
Andrew purchased some drinks and some chips. Each bag of chips cost $2.00 and
each drink cost $2.50. The expression 2x + 2.5y gives the total amount of money
spent by Andrew on chips and drinks. What is the meaning of the term 2.5y?
Answer:
2.5y=amount spent on drinks
Step-by-step explanation:
If chips are $2 and drinks are $2.50 and we do not know how many he bought of each, we put this into an equation which is
2x+2.5y
x=number of bags of chips while the 2 is two dollars per bag
so, if he bought 2 bags of chips 2(2)= $4 spent.
y= number of drinks and 2.5 is $2.5 per drink, so if he bought 4 drinks:
2.5(4)= $10 spent on drinks.

|-4| + |-5| i need help!!!
Answer:
9
Step-by-step explanation:
The absolute value of any number is just its distance from 0.
-4 is 4 away from 0, so its absolute value is 4.
-5 is 5 away from 0, so its absolute value is 5.
Therefore, the equation is basically just asking what is 4 + 5, which is 9 :D.
Answer:
9
Step-by-step explanation:
The bars around the two numbers imply that it wants you to find the absolute value. Absolute value is the distance a number is from zero since distance is always positive to find the answer just make the number positive. Following this rule l-4l=4 and l-5l=5. Then add them together 4+5=9.

A line segment that forms a right angle with another segment at its midpoint
is a
A. angle bisector
B. perpendicular bisector
C. regular polygon
D. rectangle
Answer:
B
Step-by-step explanation:
Please mark brainliest if I helped.
A line segment that forms a right angle with another segment at its midpoint is a perpendicular bisector.
Option B is the correct answer.
What is a line segment?A line segment is part of a line that is bounded by two distinct endpoints and contains every point on the line between its endpoints.
It can be measured by its length and is finite in size.
We have,
A perpendicular bisector is a line or line segment that cuts another line segment into two equal parts and forms a right angle with it.
The midpoint of the line segment is the point where the perpendicular bisector intersects it.
Therefore, if a line segment forms a right angle with another segment at its midpoint, it is a perpendicular bisector since it cuts the segment into two equal parts and forms a right angle with it.
Thus,
A line segment that forms a right angle with another segment at its midpoint is a perpendicular bisector.

Answer:
C. 35
Step-by-step explanation:
I just went through all the numbers, multiplied them by 2, because you start with x which is 50, and the goal is to get to 120 with 50 and a number multiplied by two, so I tried 35 which would be 70 when multiplied by two, then added 50, which would make 120.

A sample of 87 glass sheets are measured for thickness. They have a sample mean of 4.20 mm and a sample standard deviation of 0.10 mm. What is the level of the confidence interval (4.185, 4.215)?
Answer:
83.85%
Step-by-step explanation:
The formula for confidence interval
= Mean ±( z × Standard deviation/√n)
Confidence Interval = Mean ± Margin of Error
Mean = 4.20mm
n = 87
Standard deviation = 0.10mm
z = ????
Hence:
Confidence Interval = Mean ± Margin of Error
Step 1
We find the Margin of Error
(4.185, 4.215) = 4.20 ± Margin of Error
4.20 - 4.185 = 0.015
4.215 - 4.20 = 0.015
Hence, Margin of Error = ± 0.015
Step 2
We find the z score
Margin of Error = z × Standard deviation/√n
±0.015 = z × 0.10/√87
± 0.015 = 0.0107211253z
z = ±0.015/0.0107211253
z = 1.39910686428
z score ≈ 1.4
Step 3
We find the confidence interval that corresponds to 1.4
Using the z table to find the Probability
P(z = 1.4) = 83.85%
Therefore, the level of the confidence interval (4.185, 4.215) is 83.85%
Answer:
[4.1mm to 4.3mm]
Step-by-step explanation:
Sample size = 87 glass sheets
Sample mean = 4.2mm
Sample standard deviation = 0.1mm
Confidence interval or level = the range from lower limit of sample mean to upper limit of sample mean
[4.2 - 0.1] to [4.2 + 0.1] = [4.1mm to 4.3mm]

Members of a youth group held a bake sale to raise money for their summer trip. They sold 30 cakes, 40 pies, and 200 giant cookies, and raised a total of $684.50. The price for a pie was $2.00 less than the price of a cake. The price of a cake was 5 times as much as the price for a giant cookie. Find the price for each item at the bake sale
Answer: Cost of a giant cookies = $1.39
Cost of a cake= $6.95
Cost of a pie= $4.95
Step-by-step explanation:
Let price of a giant cookie = x
Then,
price of a cake = 5x
Price of a pie = 5x-2
Cost of 30 cakes, 40 pies, and 200 giant cookies = 30 (5x)+40(5x-2)+200x
= 150x+200x-80+200x [By distributive property a(b+c)=ab+ac]
= 550x-80
Given cost = $684.50
[tex]\Rightarrow\ 550x-80=684.50\\\\\Rightarrow\ 550x= 684.50+80[/tex]
[tex]\Rightarrow\ 550x=764.50\\\\\Rightarrow\ x=\dfrac{764.50}{550}\\\\\Rightarrow\ x=1.39[/tex]
Cost of a giant cookies = $1.39
Cost of a cake = 5 x $1.39 = $6.95
Cost of a pie = $6.95 - $2 = $4.95

IQ scores have a mean of 100 and a standard deviation of 15. Kate has an IQ of 121. (a) What is the difference between Kate's IQ and the mean
Answer:
(a) The difference between Kate's IQ and the mean is 21
(b) The z score is 1.4
Step-by-step explanation:
Here is the complete question:
IQ scores have a mean of 100 and a standard deviation of 15. Kate has an IQ of 121. (a) What is the difference between Kate's IQ and the mean (b) Convert Kate's IQ score to a z score.
Step-by-step explanation:
(a) To determine the difference between Kate's IQ and the mean, this can be done by subtracting the mean from Kate's IQ.
Mean = 100
Kate's IQ = 121
Difference between Kate's IQ and the mean = 121 - 100 = 21
Hence, the difference between Kate's IQ and the mean is 21.
(b) To convert Kate's IQ score to a z score,
z score is given by the formula
[tex]z =\frac{x - \mu}{\sigma}[/tex]
Where [tex]x[/tex] is the score
[tex]\mu[/tex] is the mean
and [tex]\sigma[/tex] is the standard deviation
From the question,
[tex]x[/tex] = 121
[tex]\mu[/tex] = 100
[tex]\sigma[/tex] = 15
Then, the z score is
[tex]z =\frac{x - \mu}{\sigma}[/tex]
[tex]z =\frac{121 - 100}{15}[/tex]
[tex]z =\frac{21}{15}[/tex]
[tex]z =\frac{7}{5}[/tex]
z = 1.4
Hence, the z score is 1.4.
