The number of contaminating particles on a silicon wafer prior to a certain rinsing process was determined for each wafer in a sample of size 100, resulting in the following frequencies: Number of particles 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Frequency 1 2 3 12 11 15 18 10 12 4 5 3 1 2 1 a. What proportion of the sampled wafers had at least one particle
) What proportion of the sampled wafers had at least one particle? At least five particles? (Round your answers to two decimal places.)
Answer:
0.99
0.71
Step-by-step explanation:
The total number of frequency is 100 when added together
A.
The proportion with at least one particle.
Here we are to get :
Total frequency - (frequency of cases whose particles are 0.)
= 100-1
= 99
99/100
= 0.99
B.
At least 5 particles:
Total number of frequency - (cases that have frequencies with 4 or less particles)
= 100 - (12+11+3+2+1)
= 100 - 29
= 71
71/100
= 0.71
Suppose that 19 inches of wire costs 76 cents.
At the same rate, how many inches of wire can be bought for 52 cents?
Answer:
13 inches of wire can be bought for 52 cents.
Step-by-step explanation:
→ We can use proportion to solve:
[tex] \frac{19 \: inches}{76 \: cents} = \frac{x}{52 \: cents} \\ \\ \frac{76x}{76} = \frac{988}{76} \\ \\ x = 13[/tex]
Stefan sells Jin a bicycle for $137 and a helmet for $17. The total cost for Jin is 140% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make bying the bicycle and helmet to Jin? Stefan originally spent $
Answer:
Stefan originally spent $110.
Stefan made a profit of $44.
Step-by-step explanation:
Given that:
Stefan sold the bike and helmet for $137 and $17
Total amount = 137+17 = $154
This is 140% of the price Stefan originally paid.
Let,
x be the original price paid by Stefan
140% of x = $154
[tex]\frac{140}{100}x=154\\1.4x = 154\\\frac{1.4x}{1.4}=\frac{154}{1.4}\\x=110[/tex]
Therefore,
Stefan originally paid $110 for the bicycle and helmet.
Profit made by Stefan = 154-110 = $44
Hence,
Stefan originally spent $110.
Stefan made a profit of $44.
Which description is paired with its correct expression?
Four less than the quotient of a number cubed and seven 4 - n3/7 + 3
Five times the difference of a number squared and six 5(6 - n2)
Nine more than the quotient of six and a number cubed decreased by 4 9 + n3/6 - 4
Twice the difference of nine and a number squared 2(9 - n2)
I think it’s D
Please help
Answer:
D.
Step-by-step explanation:
Hi there! You’re correct.
Twice the difference of nine and a number squared would look like

Marneshia walked 3/8 of a mile in 3/5 of an hour. What equation can be used to calculate her unit rate in miles per hour? (1 point)
1). 3/8
3/5. = 5/8 mile per hour
2). 3/8
3/5 = 1 3/5 miles per hour
3). 3/5
3/8=1 3/5 miles per hour
4). 3/5
3/8 = 5/8mile per hour
Answer:
Step-by-step explanation:
Using D / T = R, we have
(3/8)miles / (3/5) hrs =
3/8 x 5/3 =
5/8 mph

Simplify 6/6^1/4 rational exponents
Answer:
we conclude that:
[tex]\frac{6}{6^{\frac{1}{4}}}=6^{\frac{3}{4}}[/tex]
Step-by-step explanation:
Given
The expression is
[tex]\frac{6}{6^{\frac{1}{4}}}[/tex]To determine
Simplify the expression
Simplifying the expression
[tex]\frac{6}{6^{\frac{1}{4}}}[/tex]
Apply the exponent rule: [tex]\frac{x^a}{x^b}=x^{a-b}[/tex]
[tex]\frac{6}{6^{\frac{1}{4}}}=6^{1-\frac{1}{4}}[/tex]
Subtract the numbers: [tex]1-\frac{1}{4}=\frac{3}{4}[/tex]
[tex]=6^{\frac{3}{4}}[/tex]
Therefore, we conclude that:

Step-by-step explanation:

The recipe makes 4 qt. 1/2 gallon is 2 quarts. 3 pints is 1.5 quarts. 2 cups is 0.5 quarts. Total = 2+ 1.5 +0.5 = 4 qt
Step-by-step explanation:
The total cost of 3 bags of chips and 4 jars of salsa at a
store is $11.25. The cost of each bag of chips is $2.75.
Write an equation that can be used to determine the cost
,
X, of 1 jar of salsa.
Answer: 2.75(3) + 4x = 11.25
Step-by-step explanation:
It says each bag costs $2.75 and there are 3 bags so multiply those 2 and then subtract them from the total cost (11). What you get after you subtract is the total costs of the salsa so divide that by 4 to get the cost of each, in this case it doesn't ask so we leave it as 4x.

two trucks leave a factory at the same time. one travels east 60 miles per hour, and the other travels west at the 39 miles per hour. in how many hours will they be 150 miles apart?
9514 1404 393
Answer:
1 17/33 hours, about 1.52 hours
Step-by-step explanation:
The distance between the trucks is increasing at the rate of 60+39 = 99 miles each hour. Then the time to get to a separation distance of 150 miles is ...
(150 mi)/(99 mi/h) = (150/99) h = 1 17/33 h
The trucks will be 150 miles apart after ...
1 17/33 hours, about 1 hour 30 min 55 seconds.
