Ok, you want to put a dot on the -1 going vertically and then go down seven points and one to right, then place a dot.

Answer:

Given function:

y = -7x - 1

This is a linear function. To graph this you need to plot two different points and connect them with a line.

Examples of the points:

x = 0, then
y = -7*0 - 1 = -1

and

x = 1, then
y = -7*1 - 1 = -8

So the points are:

(0, -1) and (1, -8)

The value of a computer which was bought for rs40,000 depreciates at 10%annually what will be the cost of computer after 2 years

aalyn [17]

Answer:

Rs32400

Step-by-step explanation:

By the first year, it will decrease by : 40000 x 10% = 4000
The price will be : 40000 - 4000 = 36000 (Rs)

The next year, it will decrease by : 36000 x 10% = 3600
The price will be : 36000 - 3600 = 32400(Rs)

Hope it helps :)

Temperature at 9:00PM was 15° By 5 AM the temperature had dropped 20° what was the temperature at 5 PM

Arisa [49]

From 9 P.M. to 5 A.M. the temperature dropped 20°, making the rate over 8 hours, -2.5° Per Hour. By 5 A.M., the temperature is -5° since we had to do 15 - 20. From 5 AM to 5 P.M. is 12 hours so -2.5 x 12 = -30 making 30 how much the temperature dropped between 5 A.M. to 5 P.M. Finally, our last equation is -5 - 30 making -35 our answer.

Can somebody help me on 23 and 24, it’s geometry

alexdok [17]

Answer:

23. x = 4; DE = 44

24. x = 25; DS = 28

Step-by-step explanation:

23. Point S is the midpoint of DE, so ...

DS = SE

3x +10 = 6x -2

12 = 3x . . . . . . . . . add 2-3x

4 = x . . . . . . . . . . . divide by 3

Then DS has length ...

DS = 3x +10 = 12 +10 = 22

and DE is twice that length, so ...

DE = 44

24. DS is half the length of DE, so is ...

DS = DE/2 = 56/2

DS = 28

Then x can be found from ...

DS = x +3

28 -3 = x = 25 . . . . . substitute value for DS

_____

Comment on problem 24

Sometimes it is easier to work parts of a problem out of sequence. Here, finding DS first makes finding x easier.

For consumers making purchases online, 60% have devices made by Apple, 85% own a smartphone, and 75% use Venmo. Also, out of the

kompoz [17]

Answer:

The probability that a customer selected at random has an Apple device or own a smartphone or both is 0.94

Step-by-step explanation:

The percentage of costumers that have a device made by Apple = 60%

The percentage of customers that own a smartphone = 85%

The percentage of customers that use Venmo = 80%

The percentage out of the smartphone users that use Venmo = 80%

The probability both independent events A and B occurring = P(A) × P(B)

The exclusive probability of A or B occurring P(A XOR B) = P(A) + P(B) - 2 × P(A ∩ B)

Therefore, the probability of A or B or both occurring is given as follows;

P(A or B or Both) = P(A) + P(B) - 2 × P(A ∩ B) + P(A) × P(B)

Where A represent the percentage of costumers that have a device made by Apple and let B represent the percentage of users that have a smartphone, we have;

P(A or B or Both) = 0.6 + 0.85 - 2×0.6×0.85 + 0.6 × 0.85 = 0.94

Therefore, the probability that a customer selected at random has an Apple device or own a smartphone (or both), P(A or B or Both) = 0.94
