Answer:

M= -4

Step-by-step explanation:

1. Distribute the 5 into the parentheses

5m-5=-25

2. Now add 5 on both sides

5m=-20

3. Now divide 5 by -20

m=-4

Answer:

The equation is true

Step-by-step explanation:

First, input -4 instead of m in the equation:

5(-4 - 1) = -25

Then, distribute:

-20 - 5 = -25

Finally, simplify:

-25 = -25

This equation is true, and that's how you prove it.

Hope this helps!

Of the volunteers donating blood in a clinic, 30% have the Rhesus (Rh) factor present in their blood. (a) If five volunteers are
maksim [4K]

Answer:

0.83193

Step-by-step explanation:

Probability of having the Rhesus (Rh) factor present in their blood; p = 0.3

Sample size; n = 5

We want to find the probability the probability that at least one does not have the Rh factor.

This will be;1 - P(X < 1)

This is a binomial probability distribution. Thus;

P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)

P(X < 1) = P(X = 0)

Thus;

P(X = 0) = C(5, 0) × 0.3^(0) × (1 - 0.3)^(5 - 0)

P(X = 0) = 1 × 1 × 0.16807

P(X = 0) = 0.16807

Thus;

1 - P(X < 1) = 1 - 0.16807 = 0.83193

Santos flipped a coin
marusya05 [52]

Answer:

5/12

Step-by-step explanation:

We know that Santos flipped the coin a total of 300 times. Out of the 300 times, he flipped 125 heads. We need to find a simplified ratio equivalent to:

125/300

First, a common factor is 5, so we can divide both sides by 5 to get:

25/60

We can divide it by more to simplify it down, so we can try another 5 to get:

5/12

5/12 would be the simpliest form

So 125/300 is equal to 5/12

Other forms: 5:12, 0.42, %42
