The sum of three numbers is 8. twice the smaller is 2 less than the largest, while the sum of the largest and smallest is 5. use

Lorico [155]

X + Y + Z = 8
2x = Z - 2
X + Z = 5
X = 1
1 + Y + Z = 8
Y + Z = 6
1 + Z = 5
Z = 4
1 + Y + 4 = 8
5 + Y = 8
Y = 3
The variables are 1, 3, 4.

The planner needs a clearance of 9 feet under the arch. Has the planner met the minimum height?

Assoli18 [71]

Answer:

Yes,planner has met the minimum height, as minimum height was 9 feet and maximum height of arc is 9.6 feet

Step-by-step explanation:

The question is incomplete as all the details have not been given in the question.I have attached the complete question and its options at the bottom. Consult in for better understanding.

As we can see that at the mid value, for x=4, the value of f(x)=9.4

It means that the maximum height occurs at mid of the arc where it is height is 9.6 feet above the ground.

It means that the planner has met the minimum height, as minimum height was 9 feet and maximum height of arc is 9.6 feet

$\huge \huge \huge\huge\mathrm{ \boxed{ \boxed{ \boxed{ \boxed{ \boxed {\boxed{ \huge\mathfrak{ Solution}}}}}}}}$

$\sqrt{x - 1} - x = - 7$

$\sqrt{x - 1} =x - 7$

$x - 1 = (x - 7) {}^{2}$

$x - 1 = {x}^{2} + 49 - 14x$

${x}^{2} - 14x + 49 - x + 1 = 0$

${x}^{2} - 15x + 50 = 0$

${x}^{2} - 10x - 5x + 50 = 0$

$x(x - 10) - 5(x - 10) = 0$

$(x - 5)(x - 10) = 0$

$x = 5 \: \: \: or \: \: \: x = 10$

olice response time to an emergency call is the difference between the time the call is first received by the dispatcher and the

yan [13]

Answer:

0.7823 = 78.23% probability that the response time is between 3 and 9 minutes.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 7.2 minutes and a standard deviation of 2.1 minutes.

This means that $\mu = 7.2, \sigma = 2.1$
