Answer:
ST = 7.1 in
Step-by-step explanation:
we can use SOH-CAH-TOA because we've got a right triangle
side ST would be 'adjacent'
side TU would be the 'hypotenuse'
so we use Cosine because that's used when you're dealing with adjacent and hypotenuse:
cos 42° = ST/9.5
ST = cos 42° × 9.5
ST = 7.1
Answer:
<u>C) 2parts that are one eight each.</u>
Step-by-step explanation:
The reason I chose <u>C)</u> as the correct answer is becasue I evaluated it with the steps below.
A) - 8 parts that are one fourth each.
<u>This cannot be correct because it would surpase the 2/8ths (would be over).</u>
B) - 4 parts that are one-half each.
<u>This cannot be correct because it would surpass the 2/8ths (would be over).</u>
C) - 2parts that are one eight each.
<u>This can be correct because 2 parts have 1/8th. 1/8 + 1/8 = 2/8.</u>
D) - 2parts that are one fourth each.
This cannot be correct because the denominator is not 8, it is 4 meaning it wouldn't fit into the format the question asked for (which was 2/8).
<u>This makes the correct answer C).</u>
<u></u>
I hope this helps you understand and helps you in your question.
Answer:
0.7455
Step-by-step explanation:
First, we note that there are C = 220 ways of selecting the defective items.
The probability that the inspector will have to test at least 9 widgets would be 1 minus the probability that the inspector will have to test 8 or less widgets.
This is 1 - P(8 or less widgets have to be checked)
1 -
= 1 - 56/220
= 1 - 0.2545
= 0.7455
Answer:
y = -5x + 12
Step-by-step explanation:
First remember the equation y = mx + b
We have values for x, y, and m so all we need to do is solve for b.
2 = -5 (2) + b
2 = -10 + b
12 = b
Then plug that value back in and keep the variables for x and y
y = -5x + 12
