Answer: 50 miles per hour

Step-by-step explanation:

The average speed of the car will be gotten by using the formula:

= Distance/Time

where,

Distance = 65 miles

Time = 14:48 - 13:30 = 1:18 hours = 1 hour 18 minutes = 1 18/60 = 1.3 hours

Speed = Distance / Time

= 65 miles / 1.3 hours

= 50 miles per hour

Is the relation a function, and what is the range?<br> Please help.
nadya68 [22]

Answer:

the last option or D

Step-by-step explanation:

Not a function because x-values repeat and to find the range you grab all the y-values. If y-value repeats the same number then you would take one of the numbers. Don't add it or anything, just count it as one number.

Solve the inequality. 2(4+2x)≥5x+5<br> x≤−2 <br> x≥−2 <br> x≤3<br> x≥3
KATRIN_1 [288]
<h2>Answer:</h2>

The solution of the inequality is:

                       x\leq 3

<h2>Step-by-step explanation:</h2>

We are given a inequality in terms of variable x as:

2(4+2x)\geq 5x+5

Now we are asked to find the solution of the inequality i.e. we are asked to find the possible values of x such that the inequality holds true.

We may simplify this inequality as follows:

On using the distributive property of multiplication in the left hand side of the inequality we have:

2\times 4+2\times 2x\geq 5x+5\\\\i.e.\\\\8+4x\geq 5x+5\\\\i.e.\\\\8-5\geq 5x-4x\\\\i.e.\\\\x\leq 3

The solution is:      x\leq 3

Possible values of X, the number of components in a system submitted for repair that must be replaced are 1,2,3, and 4 with corr
Vesnalui [34]

Answer:

Step-by-step explanation:

Given that the possible values of X, the number of components in a system submitted for repair that must be replaced are 1,2,3, and 4 with corresponding probabilities 0.15, 0.35, 0.35, and 0.15 respectively.

X       1         2        3        4

p    0.15   0.35    0.35    0.15       1

x*p 0.15   0.70    1.05     0.60     2.50

a)E(x) = 2.50

By linearity property

E(5-x) = 5-E(x) = 2.50

b) If fees it 75 then charges would be75(2.5) = 187.50

Else repair charges = \frac{150}{E(5-x)} \\=60

II one is better
