Answer:

B) Complementary angles

Step-by-step explanation:

∠AXB + ∠CXB = 180    { Straight line}

∠AXB + 90 = 180          { given  ∠CXB=90}

∠AXB = 180 - 90

∠AXB = 90

a + b = 90

If sum of two angles is 90, then the two angles are complementary angles.

What is the value of the function at x = 3?<br><br> Enter your answer in the box.
butalik [34]

Answer:

4

Step-by-step explanation:

Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?

To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.

Here it is 4.

Answer:

Gallons of punch used = 4.94 gallons

Step-by-step explanation:

Given that:

Liters of punch purchased = 25 liters

Liters of punch left over = 6 liters

Liters of punch used = 25 - 6 = 19 liters

According to the given statement;

1 liter = 0.26 gallons

19 liters = 0.26*19 gallons

19 liters = 4.94 gallons

Hence,

Gallons of punch used = 4.94 gallons

Find the probability of atleast three successes in six trials of a binomial experiment in which the probability of success is 50
yan [13]

The binomial cumulative probability with p=0.5 for 3+ successes is as follows:

P(3+)=\sum_{k=3}^6 {{6}\choose{k}}p^k(1-p)^{6-k}

for p=0.5 (50% success rate) it becomes:

P(3+)=\sum_{k=3}^6 {{6}\choose{k}}0.5^6=\frac{21}{32}=0.65625

the probability is 0.65625, or about 66%
