Answer:
area left = (3x² + 6x - 24) in²
Step-by-step explanation:
the area of poster board left
= area of poster board - area of square cut out
= 4x² + 14x - 8 - (x² + 8x + 16) ← distribute parenthesis by - 1
= 4x² + 14x - 8 - x² - 8x - 16 ← collect like terms
= (4x² - x² ) + (14x - 8x) + (- 8 - 16)
= 3x² + 6x + (- 24)
= (3x² + 6x - 24) in²

Answer:
The lifetime value needed is 11.8225 hours.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by
After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we This p-value is the probability that the value of the measure is greater than X.
In this problem, we have that:
The lifetime of a certain type of battery is normally distributed with mean value 11 hours and standard deviation 1 hour. This means that .
What lifetime value is such that the total lifetime of all batteries in a package exceeds that value for only 5% of all packages?
This is the value of THE MEAN SAMPLE X when Z has a pvalue of 0.95. That is between Z = 1.64 and Z = 1.65. So we use
Since we need the mean sample, we need to find the standard deviation of the sample, that is:
So:
The lifetime value needed is 11.8225 hours.
Explanation:
To find the value, put 320 where x is and do the arithmetic.
f(320) = 0.11·320 +43 = 35.20 +43 = 78.20
The meaning is described by the problem statement:
"how much Derek pays for phone service" for "the number of minutes, [320], used for international calls in a month."
Derek pays 78.20 for 320 minutes of international calls in a month.
__
The units (dollars, rupees, euros, pounds, ...) are not specified.
Answer:
Given the function f(x) = 0.11x + 43, this shows the relationship between how much Derek has to pay for phone service for the amount of minutes he uses on international calls a month. f(320) can be solved by substituting x = 320, and this is shown below: f(x) = 0.11x + 43 f(320) = 0.11(320) + 43 f(320) = 78.2 This means that Derek has to pay $78.20 for the 320 minutes of calls. Among the choices, the correct answer is B.
Answer:
0.1719
Step-by-step explanation:
Given that:
A quiz contains 20 questions and 10 questions have been answered rightly
We are to determine the probability of getting a total quiz score of 85%
i.e 0.85 (20) = 17
Let's not forget that 10 is correctly answered out of 17. that implies that we only have 7 more questions to make a decision on.
where;
n = 10,
p + q = 1, 0.5 + q = 1
q = 1 - 0.5
q = 0.5
Let X be the random variable that follows the binomial distribution. Then ;
where x = 7
P(X ≥ 7) = 0.1719
