The temperature in Alaska is -10°F at midnight. At 9 am the temperature has risen 8°F. What is the temperature at 9 am?

The probability that a machine works on a given day is based on whether it was working in the previous day. If the machine was w

VashaNatasha [74]

Answer:

73.03% probability that it will be working two days from now

Step-by-step explanation:

The machine is broken today.

If the machine is broken on a day, the following day, it has a 1-0.33 = 0.67 probability of working on the next day.

Otherwise, if it is works correctly on a day, it has a 0.76 probability of working on the next day.

Uf the machine is broken today, what is the likelihood that it will be working two days from now

Either of these outcomes are acceptable:

Tomorrow - 2 days from now

Not working - working

Working - Working

Not working - working

Today, it does not work. So tomorrow the probability of not working correctly is 0.33. Then, if tomorrow does not work, 0.67 probability of working correctly two days from now

0.33*0.67 = 0.2211

Working - Working

Today, it does not work. So tomorrow the probability of working correctly is 0.67. Then, if tomorrow works, 0.76 probability of working correctly two days from now

0.67*0.76 = 0.5092

Total

0.2211 + 0.5092 = 0.7303

73.03% probability that it will be working two days from now

Graph the image of the given triangle under a dilation with a scale factor of –4 and center of dilation (0,0).

Dvinal [7]

Step-by-step explanation:

Hey there!

The coordinates of a triangle are;

A (1,2)
B (1,-2)
C (-2,-2)
Scale factor = -4 and centre at (0,0)

Now, We have;

P(x,y)----------- P'(kx, ky)

Keep formula;

A(1,2)---------- A'(-4×1 ,-4×2)

= A'(-4, -8)

B(1,-2)------------- B'(-4,8)

C(-2,-2)-------------C'(8,8)

[ The A' should be kept in (-4,-8). There was no place in this graph so, i kept it just below -7. Please while plotting remember to keep it on "-8".]

Hope it helps..

What is the slope of the line that passes through points (1,7),(10,1)

astra-53 [7]

Answer:
slope = -2/3

Explanation:
Slope of line can be calculated using the following formula:
slope = $\frac{y2-y1}{x2-x1}$

We are given:
point (1,7) representing (x1,y1)
point (10,1) representing (x2,y2)

Substitute with the givens in the above formula to get the slope as follows:
slope = $\frac{1-7}{10-1}$ = -2/3

Hope this helps :)
