0.9 is the answer to your question
X = 5!
4x+1=2x+11
-1 -1 (Subtract 1 from both sides)
4x =2x+10
-2x -2x (Subtract 2x from both sides)
2x = 10
—— ——
2x 2x (Divide both sides by 2x)
X = 5

Step-by-step explanation:
65.75 - 36.50 = 29.25
29.25 \ 6.50 = 4.5
Your answer is 4.5 hours
Answer:
(a) 0.343
(b) 0.973
(c) 0.189
Step-by-step explanation:
We are given that Probability of all vehicles examined at a certain emissions inspection station pass the inspection is 70% or 0.7 .
(a) <em>P(all of the next three vehicles inspected pass)=P(First vehicle passes the</em>
<em> inspection test) * P(Second vehicle passes the inspection test) * P(Third </em>
<em> vehicle passes the inspection test)</em>
= 0.7 * 0.7 * 0.7 = 0.343.
(b) P(at least one of the next three inspected fails) = 1 - P(none of the next
three inspected fails)
= 1 - ((1 - 0.7) * (1 - 0.7) * (1 - 0.7)) = 1 - 0.027 = 0.973
{ Because if probability of passing the inspection is 0.7 then probability of not passing will be 1 - 0.7 } .
(c) P(exactly one of the next three inspected passes) = It means that one of the three vehicles get passed the inspection.
- First vehicle passed the inspection , second and third does not pass.
- Second vehicle passed the inspection, first and third does not pass.
- Third vehicle passed the inspection, first and second does not pass.
Hence, <em>P(exactly one of the next three inspected passes)</em>
= 0.7 * (1-0.7) * (1-0.7) + (1-0.7) * 0.7 * (1-0.7) + (1-0.7) * (1-0.7) * 0.7
= 0.189 .
Answer:
(D) Quantitative
Step-by-step explanation:
Bivariate data involves two types of variables. Categorical data will have a number of different categories. Continuous data usually includes a range of values so is likely to be in decimals. Quantitative data will be collected in this scenario as it will be calculated the number of times each shirt is tried on.
