(6a −? )5a =? a2 − 35a
Karolina [17]
Answer:
5a(6a-7) = 30a² - 35a

Explanation:
Before we begin, remember the following:
a(b+c) = ab + bc

Now for the given:
Assume that the first question mark is x and that the second question mark is y.

The expression now becomes:
(6a-x) * 5a = ya² - 35a
Distribute the 5a over the bracket and equate it with the right-hand side as follows:
5a(6a) - 5a(x) = ya² - 35a
30a² - 5ax = ya² - 35a

By comparison:
30a² = ya² ..............> This means that y = 30
-5ax = -35a
-5x = -35
5x = 35
x = 35/5
x = 7

Based on the above, the expression is:
5a * (6a-7) = 30a² - 35a

Hope this helps :)

A test to determine whether a certain antibody is present is 99.1​% effective. This means that the test will accurately come bac
avanturin [10]

Answer:

The probability that all the six people will test negative for the antibody is 0.9472.

The probability that the test comes back positive for at least one of the six ​people is 0.0528

Step-by-step explanation:

Consider the provided information.

probability that antibody is present will be effective is 99.1​% and not present​ is 99.1​% of the time.

Part (A)What is the probability that the test comes back negative for all six ​people? ​

Let P(X)= P(Antibody not present)

We want test comes back negative for all six that means antibody is present for all six. Thus X=0

P(X=0)=0.991\times0.991\times0.991\times0.991\times0.991\times0.991\\P(X=0)=0.9472

The probability that all the six people will test negative for the antibody is 0.9472.

Part (B) What is the probability that the test comes back positive for at least one of the six ​people?

P(X \geq1)=1-P(X=0)

P(X \geq1) = 1-0.9472

P(X \geq1) = 0.0528

Hence, the probability that the test comes back positive for at least one of the six ​people is 0.0528
