Pasha works as a food scientist. He designed a recipe for crackers that are 65% wheat flour by weight. He made a test batch of the crackers from total pounds of ingredients. What weight of wheat flour did Pasha use in the test batch?
Answer:
13/16
Step-by-step explanation:
Here is the complete question
Pasha works as a food scientist. He designed a recipe for crackers that are 65% wheat flour by weight. He made a test batch of the crackers from 1 1/4 total pounds of ingredients. What weight of wheat flour did Pasha use in the test batch?
Weight of wheat flour = percentage of wheat in the recipe x total pounds of ingredients
the first step is to convert 65% to a fraction. To do this, express 65 as a fraction of 100 and express the fraction in its lowest term
[tex]\frac{65}{100}[/tex]
Dividing the numerator and denominator by 5 gives
[tex]\frac{13}{20}[/tex]
Now multiply 13/20 by 5/4
[tex]\frac{13}{20}[/tex] ×[tex]\frac{5}{4}[/tex] = [tex]\frac{13}{16}[/tex]
The manufacturer of a laser printer reports the mean number of pages a cartridge will print before it needs replacing is 12,200. The distribution of pages printed per cartridge closely follows the normal probability distribution and the standard deviation is 820 pages. The manufacturer wants to provide guidelines to potential customers as to how long they can expect a cartridge to last. How many pages should the manufacturer advertise for each cartridge if it wants to be correct 99% of the time
Answer:
14110
Step-by-step explanation:
Let x = number of pages ;
μ = 12200 ; σ = 820
Zscore = (x - μ) / s
Zscore = (x - 12200) / 820
Zcritical at 99% confidence, for a 1 - tail test is 2.33
Hence, Z at 99% = 2.33
Put Zscore = 2.33
Zscore = (x - 12200) / 820
2.33 = (x - 12200) / 820
2.33 * 820 = x - 12200
1910.6 = x - 12200
1910.6 + 12200 = x
x = 14110.6
x = 14111
The number of pages the manufacturer should advertise is 14,110

10/9 = 1 1/9
26/15 = 1 11/15
Step-by-step explanation:
3/8 / 4/5 = 3/8 * 5/4 = 15/32
8/9 / 4/5 = 8/9 * 5/4 = 40/36 = 10/9 = 1 1/9
2 3/5 / 1 1/2 = 13/5 / 3/2 = 13/5 * 2/3 = 26/15 = 1 11/15

What is 1 1/6 + 2 3/8 equal to?
Answer: 3 13/24
Step-by-step explanation:
First off we have an issue with the problem due to denominators not being the same
So we need to find a common denominator
The common denominator would be 24 for 6 and 8
Then we must multiply the numerator 1 by 4 and the numerator 3 by 3
Our new problem would look like
1 4/24 + 2 9/24
Now we add it all up

yokoreceived a 70 gift card for a coffee store. She used it in buying some coffee that cost 8.04 per pound. After buying the coffee, she had 45.88 left on her card. How many pounds of coffee did she buy?
Answer:
Since she started with $80 and ended with with $35,24, we can find the total amount she spent by subtracting these amounts:
$80 - $35.24 = $44.76
This means that she spent $44.76 on coffee. If each pound cost $7.46, we can divide $44.76 by $7.46 to see how many pounds she bought (ignoring tax):
44.76 / 7.46 = 6 pounds of coffee purchased

You have a bag that contains 6 red marbles and 3 blue marbles. You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Answer:
12/27
Step-by-step explanation:
You have a bag that contains 6 red marbles and 3 blue marbles. You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Let the total number of marbles = 6 red marble + 3 blue marbles = 9 marbles
You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. Find the probability of the events.
Assume all you picked is red( without replacement)
= 6/9 × 5/9
= 30/81
= 10/27
Assume all you picked is blue( without replacement)
= 3/9 × 2/9
= 6/81
= 2/27
The probability of the events is calculated as:
All red or All blue
= 10/27 + 2/27
= 12/27

Answer:
7.2 inches
Step-by-step explanation:
First, we find the length of the legs, which are the sides that are parallel to the x- and y-axis.
The leg parallel to the x-axis is 6 inches long.
The leg parallel to the y-axis is 4 inches long.
After finding the length of both legs, we can use the Pythagorean Theorem to find the length of the hypotenuse: a² + b² = c²
a and b being the legs, and c being the hypotenuse
6² + 4² = c²
36 + 16 = c²
52 = c²
√52 = c
c ≈ 7.2 inches

777,498,619,379,895,1,256,1052 a. What is the mediam of the first half of data?(first quatile. b. What's the mediam of second half of the data?(third quartile) c. What is the interquartile range ?
Answer:
[tex]Q_1 = 498[/tex]
[tex]Q_3 =1052[/tex]
Step-by-step explanation:
Given
[tex]Data: 777,\ 498,\ 619,\ 379,\ 895,\ 1,256,\ 1052[/tex]
[tex]n = 7[/tex]
First, the data has to be arranged:
[tex]Data: 379,\ 498,\ 619,\ 777,\ 895,\ 1052,\ 1256[/tex]
Solving (a): Lower Quartile
This is calculated as:
[tex]Q_1 =\frac{1}{4} * (N + 1)th[/tex]
[tex]Q_1 =\frac{1}{4} * (7 + 1)th[/tex]
[tex]Q_1 =\frac{1}{4} * 8th[/tex]
[tex]Q_1 = 2nd[/tex]
The 2nd data is 498
Hence:
[tex]Q_1 = 498[/tex]
Solving (b): Third Quartile
This is calculated as:
[tex]Q_3 =\frac{3}{4} * (N + 1)th[/tex]
[tex]Q_3 =\frac{3}{4} * (7 + 1)th[/tex]
[tex]Q_3 =\frac{3}{4} * (8)th[/tex]
[tex]Q_3 =6th[/tex]
The 6th data is 1052
Hence:
[tex]Q_3 =1052[/tex]
Solving (c): Interquartile Range
This is calculated as:
[tex]IR = Q_3 - Q_1[/tex]
[tex]IR = 1052- 498[/tex]
[tex]IR = 554[/tex]

Find the value of if the perimeter of the rectangle is 30inches. The length is 2x + 3and the width is x
Answer:
The perimeter of a rectangle is 30 meters. The length of the rectangles is 3 meters more than twice the width. Find the dimensions of the rectangle.
Step-by-step explanation:
Equation for Perimeter of a rectangle: Perimeter = 2W + 2L
Defining the variables, let
Width = x
Length = 2x+3 (3 more than twice the width)
Plugging everything into the equation
30= 2(x) + 2(2x+3) using the distributive property,
30=2x+4x+6 combining like terms
30=6x+6 subtracting 6 from both sides,
24=6x divide both sides by 6
4=x This means that the width is 4 m
To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved for
L=2(4)+3
L=8+3 = 11 m
So the dimensions of the rectangle are width is 4 m and length is 11 m
