Answer:

Step-by-step explanation:

Sum of 3 angles of triangle= 180

147 + 4x + x = 180

147 +5x = 180

5x = 180 - 147

5x = 33

x = 33/5

x = 6•6 (Answer)

Answer:

X = 11

Step-by-step explanation:

To solve this, we need to find all the angles within the triangle. We know one angle (f) is 33 degrees because 147 + f = 180 = f = 33. Next we need to set up two more formulas to solve for x:

4x + y = 180

x + y + 33 = 180 => x + y = 147

Next, we can isolate one of the variables in one of the formulas and plug it back into the other:

x + y = 147 => y = 147 - x

4x + y = 180 => 4x + 147 - x = 180 => 3x + 147 = 180 => 3x = 33 => x = 11

I hope this helps!

slader Suppose that 8% of all bicycle racers use steroids, that a bicyclist who uses steroids tests positive for steroids 96% of

d1i1m1o1n [39]

Answer:

P = 0.4812

Step-by-step explanation:

First, we need to use here two expressions and then do the calculations.

The first one is the conditional probability which is:

P(B|A) = P(A∩B)/P(A) (1)

The second expression to use has relation with the Bayes's theorem which is the following:

P(D|C) = P(C|D)*P(D) / P(C|D)*P(D) + P(C|d)*P(d) (2)

Now, the expression (2) is the one that we will use to calculate the probability of a selected random bicyclist who tests positive for steroids.

So, in this case, we will call C for positive and D that is using steroids and d is the opposite of d, which means do not use steroids.

Then, the probabilities are the following:

P(D) = 8% or 0.08

P(C|D) = 96% or 0.96

P(C|d) = 9% or 0.09

P(d) = 1 - 0.08 = 0.92

With these data, let's replace in expression 2

P(D|C) = 0.96 * 0.08 /0.96 * 0.08 + 0.09*0.92

P(D|C) = 0.0768 / 0.1596

P(D|C) = 0.4812 or 48.12%

Step-by-step explanation:

<h3>In Solving This You Need to Change It Into Improper Fractions First;</h3>

1 2/5×3 1/2

•You then multiply the 5 by the 1 and then add it to the 2 which is then going to be;

7/5× 3 1/2

•Then you multiply the 2 by the 3 and then add it to the 1;

7/5×7/2

•Then you proceed to multiply the first numerator by the second numerator and then also multiply the first denominator by the second denominator which will be;

14/10

After this you go on to simplify which is going to be;

7/5(NB: It was divided by two)

So mixed number in it's simplest form is going to be;

1 2/5

In Decimal form would have been; 1.4

Since the question is asking for mixed number in it's simplest form it's going to be;

1 2/5
