Find the unit rate. 6 2/5 revolutions in 2 2/3 seconds

Brums [2.3K]

The unit rate will be in revolutions per second. That means divide number of revolutions by number of seconds.

first convert from mixed fraction.
6 2/5 = 32/5 revolutions
2 2/3 = 8/3 seconds

32/5 ÷ 8/3
flip multiply
32/5 × 3/8 = 12/5 revolutions per second

12/5 = 2 2/5 revolutions per second

Jamie and Hudson took a road trip to the beach. Their total distance traveled after getting on the highway can be found using th

lukranit [14]

The total distance is an illustration of a linear function.

(1) Why the relationship is a function

The relationship is a function because all input values of h, have exactly one corresponding output value of d

(2) The function type

The function is a discrete function, because the number of hours is an integer, and it cannot take decimal values (in this case)

(3) The domain for a drive of 8 hours

The domain is the set of time the girls drive.

So, the domain is: [0,8]

(4) The range

The function is given as:

$d = 55h +10$

When h = 0,

$d = 55(0) +10 = 10$

When h = 8,

$d = 55(8) +10 = 450$

So, the range is: [10,450]

(5) The graph

See attachment

(6) The slope

A linear function is represented as:

$y = mx + c$

Where:

m represents the slope.

So, by comparison:

$Slope = 55$

The slope in this case represents the distance travelled per hour

(7) The y-intercept

In (6) above, c represents the y-intercept.

So, by comparison:

$c = 10$

The y-intercept in this case represents the initial distance

sample of 150 Publix cashiers showed a mean hourly wage of $ 8.00, with a standard deviation of $ 1. Give an interval that is li

Scorpion4ik [409]

Answer:

B. (6, 10)

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 8

Standard deviation = 1

Give an interval that is likely to contain about 95% of the sampled cashiers' hourly wages.

By the Empirical Rule, 95% of the sampled cashiers' hourly wages will be within 2 standard deviations of the mean, so from 2 standard deviations below the mean to two standard deviations above the mean

Two standard deviations below the mean:

8 - 2*1 = 6

Two standard deviations above the mean

8 + 2*1 = 10

So the correct answer is:

B. (6, 10)

4=2/4u one step equation

docker41 [41]

4 = 2/4u

Multiply both sides by 4u

16u = 2

Divide both sides by 16, and simplify.

u = 1/8
