Which set of three points is noncollinear

in a randomly generated list of numbers from 0 to 4 is being used to simulate an event with numbers 2 and 3 representing success

Arte-miy333 [17]

Answer: 40%, 0.40, 4/10 (whichever form floats your boat)

Step-by-step explanation:

0, 1, 2, 3, 4 (5 total possibilities)

2, 3 (2 success possibilities)

2 success possibilities 4

--------------------------------- = ----- = 40% = 0.40

5 total possibilities 10

Yesterday, the temperature at noon was 43.6 °F. By midnight, the temperature has decreased by 15.3 degrees. What was the tempera

ELEN [110]

Answer:

Temperature at midnight is $-15.9$ °F.

Step-by-step explanation:

Given: The temperature at noon was $43.6$ °F. By midnight, the temperature has decreased by $15.3$ degrees.

To find: The temperature at midnight.

Solution:

The temperature at noon was $43.6$ °F.

Now, by midnight, temperature has decreased by $15.3$ degrees.

So, first we need to convert the temperature in °F.

We know that, $F=\frac{9}{5}C+32$ , where F is temperature in Fahrenheit and C is temperature in Celsius.

So, $F=(\frac{9}{5} \times 15.3)+32$

$\implies F=59.5$

So, by midnight, temperature has decreased $59.5$ °F

Therefore, temperature at midnight is $43.6-59.5=-15.9$ °F

Hence, temperature at midnight is $-15.9$ °F.

Luis uses cubes to represent each term of a pattern based on a recursive function. The recursive function defined is f(n + 1) =

kari74 [83]

Answer:

figure 3: 17 cubes.

figure 4: 21 cubes.

figure 5: 25 cubes.

Step-by-step explanation:

Let the nth figure be represented by f(n).

also we are given f(n+1)=f(n)+4.

The number of cubes used in figure 1 i.e. f(1) is 9.

number of cubes used in figure 2 i.e. f(2) is 13

Now we have to find the number of cube used in figure 3, figure 4 and figure 5.

number of cubes in figure 3 i.e. f(3)=f(2)+4=13+4=17.

number of cubes in figure 4 i.e. f(4)=f(3)+4=17+4=21.

number of cubes in figure 5 i.e. f(5)=f(4)+4=21+4=25.

What is the length of an arc cut off by an angle of 1.5 radians on a circle of radius 8 inches?

Natali [406]

To solve this problem, we should first recall that the circumference is the measure of the total arc enclosing the circle. The formula for circumference is:

Circumference = 2 π r

where r is the radius of the circle

Now since we are only looking for a fraction of the arc, not the total arc, therefore this simply means we are finding for a portion of the circumference. Now we use the formula:

Arc length = (θ / 360) * 2 π r

Where θ/360 represents how much of the fraction is the arc

Convert angle to degrees: θ = 1.5 rad (180° / π rad) = (270/π)°

Therefore the arc length is:

Arc length = (270/π / 360) * 2 π (8 inches)

Arc length = 12 inches
