Answer:
0.35808
Step-by-step explanation:
Given a normal distribution :
Mean (m) = 50 lb
Standard deviation (σ) = 1.1 lb
Proportion of bags with mass more than 50.4 lbs
X : X > 50.4 lbs
Using the Zscore relation :
Zscore = (x - m) / σ
Zscore = (50.4 - 50) / 1.1
Zscore = (0.4) / 1.1
Zscore = 0.3636363
P(Z > 0.3636) = 1 - P(Z < 0.3636)
P(Z < 0.3636) = 0.64192
1 - P(Z < 0.3636) = 1 - 0.64192 = 0.35808

The time spent waiting in the line is approximately normally distributed. The mean waiting time is 55 minutes and the standard deviation of the waiting time is 33 minutes. Find the probability that a person will wait for more than 88 minutes. Round your answer to four decimal places.
Answer:
Zero.
Step-by-step explanation:
The variable here is t where t is = time spent waiting in the line
The values for this variable and in this study, are normally distributed.
The mean waiting time = 55 minutes
The standard deviation = 33 minutes
What is the probability that t is greater than 88 minutes?
Now, the confidence interval about the mean for this study is:
[55-33], [55+33] = [22, 88]
Therefore, all values of t fall within this lower and upper limit or interval.
If that is the case, and recalling also that the distribution of values is normal, then it is impossible for t to be greater than 88 minutes.
Hence, P[t>88] = 0
To 4 decimal places, that would be 0.0000
what is 1/4 mutipled by 2 1/2
Answer:
5/8
Step-by-step explanation:
Simplify the following:
(2 + 1/2)/4
Put 2 + 1/2 over the common denominator 2. 2 + 1/2 = (2×2)/2 + 1/2:
((2×2)/2 + 1/2)/4
2×2 = 4:
(4/2 + 1/2)/4
4/2 + 1/2 = (4 + 1)/2:
((4 + 1)/2)/4
4 + 1 = 5:
(5/2)/4
5/2×1/4 = 5/(2×4):
5/(2×4)

Fourteen more than three times a number is sixty-seven.
Answer:
67 = 3n + 14
Step-by-step explanation:
So we know its going to equal 67, and 3 times a number is the same as 3n more than is to show addition. That means you are adding 14 to 3n.
That's why it would be,
14 + 3n = 67

If, in a random sample of items, are defective, what is the sample proportion of defective items?
Complete Question:
If in a random sample of 400 items, 88 are defective, what is the sample proportion of defective items?
Answer:
22%
Step-by-step explanation:
Given
[tex]x = 88[/tex]
[tex]n = 400[/tex]
Required
Determine the sample proportion, p
p is calculated using the following formula
[tex]p = \frac{x}{n}[/tex]
Substitute values for x and n
[tex]p = \frac{88}{400}[/tex]
[tex]p = 0.22[/tex]
Convert to percentage
[tex]p = 0.22 * 100\%[/tex]
[tex]p = 22\%[/tex]
Hence, the proportion of defective items is 22%
The triangles are similar, and the angle bisectors are drawn from corresponding angles. what is the value of x?
Answer:
C. 6
Step-by-step explanation:
Given that both ∆s are similar, the ratio of their corresponding sides as well as the ratio of their angle bisectors would be the same.
Therefore, from the figure given, we have:
[tex] \frac{8}{x} = \frac{4}{3} [/tex]
Cross multiply
[tex] x*4 = 8*3 [/tex]
[tex] 4x = 24 [/tex]
Divide both sides by 4
[tex] x = \frac{24}{4} [/tex]
[tex] x = 6 [/tex]
