Answer:

Step-by-step explanation:

We know:

(-)(-) = (+)

(+)(+) = (+)

(-)(+) = (+)(-) = (-)

We have (-5 - c)(-1) use the distributive property a(b + c) = ab + ac

= (-5)(-1) + (-c)(-1) = 5 + c

In the year 2000,there were 8.7 deaths per 1000 reidents in the United States.If there were 281,421,906 residents in the U.S.dur

bekas [8.4K]

$\frac{deaths}{residents} \: \frac{8.7}{1000} \: \frac{x}{281421906}$
Find the "difference" between the residents but division.

281421906/1000 = 281421.906
You always have to do the same to the top
8.7×281421.906 = 2,448,370.5822

There were 2,448,370.5822 deaths

Please answer I’ll rate brainlyest

Dafna1 [17]

Answer:

54.1%

Step-by-step explanation:

From the table, the total number of patients with type-B blood is given as 183. On the other hand, the number of males with type-B blood is given as 99. The percentage of patients with type-B blood who are males can be calculated as;

(the number of males with type-B blood/the total number of patients with type-B blood) * 100%;

( 99/183) * 100 = 54.1%

Therefore, the percentage of patients with type-B blood who are males is 54.1

Using the Principle of Mathematical Induction, prove that . n ^2 − n is even for n ≥ 1

Tamiku [17]

Base case: if n = 1, then

1² - 1 = 0

which is even.

Induction hypothesis: assume the statement is true for n = k, namely that k ² - k is even. This means that k ² - k = 2m for some integer m.

Induction step: show that the assumption implies (k + 1)² - (k + 1) is also even. We have

(k + 1)² - (k + 1) = k ² + 2k + 1 - k - 1

… = (k ² - k) + 2k

… = 2m + 2k

… = 2 (m + k)

which is clearly even. QED
