(5x + 1) + 62 = (18x + 11)
solve for x:
62 = (18x + 11) - (5x + 1)
62 = 13x + 10
62 - 10 = 13x
52 = 13x
x = 52/13 = 4
Ben is baking a cake. His recipe calls for 3/4 cups of sugar and 1/3 teaspoons of butter. How much sugar does Ben need per teaspoon of butter? Leave your answer as a fraction. if u asnwer this ur the best
Answer:
Improper fraction is 9/4 cups, Mixed number is 2 1/4 cups
9/4 cups of sugar or 2 1/4 cups of sugar
Step-by-step explanation:
36 tsp are in 3/4 of a cup
so you have 1/3 : 36
1/3 is less than a whole teaspoon, so the amount of sugar would be greater than 3/4 cups
1/4 cups of sugar: 1 tsp of butter; or 108 teaspoons of sugar: 1 teaspoon of butter

Which of the following statements is true?
If the missing data value were 32, the IQR would

If the missing data value were 32, the range would

If the missing data value were 50, the IQR of the
data would change substantially.
If the missing data value were 50, the range of the
data would change substantially.
Answer:
Answer is D on e2020
Step-by-step explanation:
why does vla statistics have little to no answers available for it?
The statement that is correct is If the missing data value were 50, the range of the data would change substantially. The correct option is D.
What is the range of a data set?The range is the difference between the Maximum value of the data set and the Minimum value of the dataset.
Range = Maximum value of the data set - Minimum value of the dataset
The given data observation from the stemplot is given below.
8, 9, 9, 9, 10, 11, 12, 12, 12, 14, 15, 16, 16, 18, 18, 21, 22, 27, 27, 27, 31
Since IQR or the interquartile range is the difference between the quartiles, therefore, it won't be affected much if either of the two values 32 and 50 are added.
Now, the range of the data without 32 or 50 will be,
Range = 31 - 8 = 23
The range of the data when 32 is added,
Range = 32 - 8 = 24
The range of the data when 50 is added,
Range = 50 - 8 = 42
Hence, the statement that is correct is If the missing data value were 50, the range of the data would change substantially.

Clarkson University surveyed alumni to learn more about what they think of Clarkson. One part of the survey asked respondents to indicate whether their overall experience at Clarkson fell short of expectations, met expectations, or surpassed expectations. The results showed that 5% of the respondents did not provide a response, 26% said that their experience fell short of expectations, and 65% of the respondents said that their experience met expectations. Round your answers to two decimal places.
a. If we chose an alumnus at random, what is the probability that the alumnus would say their experience surpassed expectations
b. If we chose an alumnus at random, what is the probability that the alumnus would say their experience met or surpassed expectations?
Answer:
a) 0.04
b) 0.69
Step-by-step explanation:
Given that
P ( No response ) = 5% = 0.05
P ( Short of expectation ) = 26 = 0.26
P ( Met expectation ) = 65% = 0.65
a) the probability that the alumnus would say their experience surpassed expectations
P ( surpassed expectations) = 1 - (P(No resp )+P( Short of exp)+ P( Met exp))
= 1 - (0.05 + 0.26 + 0.65 )
= 1 - 0.96
= 0.04
b) the probability that the alumnus would say their experience met or surpassed expectations.
the probability that experience met or surpassed expectations is;
= P (met exp) + P ( surpassed exp)
= 0.65 + 0.04
= 0.69
What is the measure of the of the sector shaded above?
The area of the shaded sector is 64.1 centimetres squared.
How to find the area of a sector?The area of a sector can be represented as follows:

How to find the measure of the sector shaded?The sector of a circle is the part enclosed by two radii and the included arc of a circle.
The area of a sector is given by the formula:
A = θ/360 * πr²
where r is the radius of the circle and θ is angle subtended by the sector
In this case, we have:
θ = 150° and r = 7 cm
A = θ/360 * πr²

produce per hour?
A=
B =
C =
Answer:
A = 112 , C = 85 , B = 90
Step-by-step explanation:
A + B + C = 287
A + C = 197
A + B = 202
C = 197 - A
B = 202 - A
A + 202 - A + 197 - A = 287
A = 112
C = 85
B = 90
Machine A, B and C can produce 112, 90 and 85 bolts per hour.
What is per hour ?Per hour defines 1 hour.When ever you see the word per second, per day means in 1 sec, 1 day.
According to the given question In a factory there are three machines, A, B and C.
When all three machines are working they can produce 287 bolts per hour.
∴ A + B + C = 287...(i)
When only A and C are working, they produce 197 bolts per hour.
∴ A + C = 197...(ii)
When only machines A and B are working, the produce 202 bolts per hour.
∴ A + B = 202...(iii)
Subtracting (ii) from (i) we get
B = 90.
Putting the value of B in (iii) we get
A = 112.
And putting value of A in (ii) we get '

Answer:
image 1 ---- x = 11
image 2 ---- x = 22.5
Step-by-step explanation:
Image 1finding the value at EFB
180 - 147 = 33 degrees
since DEBC is a "Z" angle means that the value at DEB and EBC is the same value of 4x.
therefore :
FEB = 180 - 4x
therefore to find x
NB : total value of triangle is 180 degrees
180 = 33 + (180-4x) +x
180 = 33 + 180 -4x + x
180 = 213 -3x
make x the subject of formula
180-213 = -3x
-33 = -3x
x = -33/-3
x = 11
Image 2DEA = BAE
therefore BAE = 2x
DEB = 180 - 4x
ABE = 180 - 6x
NB : total value of triangle is 180 degrees
180 = 2x + (180- 4x) + (180 - 6x)
180 = 2x + 180 - 4x +180 - 6x
180 = -8x + 360
-180 = -8x
x = 22.5
if angle CDE is a straight angle, DE bisects angle GDH, angle GDE=(8x-1), angle EDH= (6x+15), and angle CDF=43 , find each measure
The measures of the angle in the triangle are; ∠CDF = 43, ∠GDE = 63°, ∠FDG = 74°
How to find the measure of an angle?From the way the problem is worded:
∠CDE is a straight angle made up of three angles:
∠CDF = 43°
∠FDG is unknown
∠GDE = 8x - 1
∠EDH is outside CDE = 6x + 15.
DE bisects GDH to form GDE and EDH.
Thus, we have;
8x - 1 = 6x + 15
x = 8
Putting 8 for x, both angles are equal to 57°.
Since ∠CDF = 43 and ∠GDE = 63° and ∠CDE ∠ 180° in total.
∠FDG = 180° - 43° - 63° = 74°
