Answers

Answer 1

Answer:

Answer:

X = 2

Y = -3

Step-by-step explanation:

Go on the Y axis and count up to 2
Then go to the X axis and count down -3 / 0.3

Now you have 2, -3

The solution of the equation is .
(Type the value of x.)

Answers

Answer:

x=14/4

Step-by-step explanation:

2x-4x+12 = -5+2x+3

-2x+12 = -2+2x

-2x-2x = -12-2

-4x=-14

x=-14/-4

x=14/4

Emily drove to town with an average speed of 32 miles per hour, and then back home with an average speed of 38 miles per hour. If her total traveling time was 42 minutes, how far is it from home to town?

Answers

Answer:

12.16 miles

Step-by-step explanation:

Speed - s, Distance - d, Time - t

Equation of time is:

t = d/s

Given,

s1 = 32 m/h, s2 = 38 m/h, t1 + t2 = 42 min = 42/60 h = 7/10 h

Total time is the sum of time values to and from the town:

d/32 + d/38 = 7/10
d/16 + d/19 = 7/5
d(1/16 + 1/19) = 7/5
d(16 + 19) = 7(16*19)/5
35d = 425.6
d = 425.6/35
d = 12.16

It is given that,

→ s1= 32 miles/h

→ s2 = 38 miles/h

Now t1 + t2 is,

→ 42 min

→ 42/60 hours

→ 7/10 hours

The formula we use,

→ Time = Distance/Speed

→ t = d/s

Then the total time is the,

Sum of time values to and from the town.

→ d/32 + d/38 = 7/10

→ d/16 + d/19 = 7/5

→ d{(1/16) + (1/19)} = 7/5

→ d(16 + 19) = (7/5) × (16 × 19)

→ 35d = 425.6

→ d = 425.6/35

→ d = 12.16

Hence, the distance is 12.16 miles.

Answers

Answer:

With the information given in the question, the blank spaces are filled thus:

Step-by-step explanation:

1. The intercept is the estimated amount of a purchase, if time spent viewing the online catalog was zero minutes.

2. The slope coefficient is the estimate of amount that a purchase charges/changes, for one extra minute spent viewing the online catalog.

3. The proportion of total variation in purchases that can be explained by variation in the minutes spent viewing an online catalog is equal to the coefficient of determination.

4. The p-value is the probability value

5. Reject the null hypothesis if there is sufficient evidence to support the claim that the regression slope coefficient is not equal to zero.

NOTE: In the case of number 5, the assumption is that;

Null Hypothesis: The regression slope coefficient = 0

Alternative Hypothesis: The regression slope coefficient ≠ 0

Other answers require numerical information and full data, in order to be computed or calculated.
