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

A new park was designed to contain two circular gardens. Garden A had a diameter 50 m, anf garden B has a diameter of 70 m. How much more edging will be needed for the larger garden than the smaller one?
Answer:
20pi
Step-by-step explanation:
C =2pi(r)
Ca = 2 (pi) (25) = 50 pi
Cb = 2 (pi) (35) = 70 pi
70pi - 50pi = 20pi
A friend has a 83% average before the final exam for a course. That score includes everything but the final, which counts for 25% of the course grade. What is the best course grade your friend can earn? % What is the minimum score would your friend would need on the final to earn a 75% for the course? %
Answer:
[tex]\mathrm{Best\:course\:grade\:possible:\:}87.25\%,\\\mathrm{Minimum\:score\:on\:final\:to\:earn\:at\:least\:a\:75\%\:for\:the\:course:\:}51\%[/tex]
Step-by-step explanation:
Assuming the maximum score for the final is [tex]100\%[/tex], we can multiply each score by its respective course weight and add them together to give a final score. If your friend did receive this maximum score of [tex]100\%[/tex], their overall grade for the course would be:
[tex]83(1-0.25)+100(0.25)=\fbox{$87.25\%$}[/tex].
To find the minimum score they need to earn a 75% for the course, we set up the following equation:
[tex]83(1-0.25)+x(0.25)=75[/tex], where [tex]x[/tex] is the minimum score she needs.
Solving, we get:
[tex]62.25+x(0.25)=75,\\x(0.25)=12.75,\\x=\fbox{$51\%$}[/tex].

Plz I will chose you the brainlest. (Chose all that apply)
Answer:
C
Step-by-step explanation:
Let us rule out the first one. c+11 is not equivalent.
The second one does not work either because it is adding the two terms instead of multiplying.
The last one does not work either because again, it is adding.
C, the third one works. This is because using multiplaction, you can rearrange the order of the terms and still get the same answer.
Therefore, the third one

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]

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]
