Answer:

Step-by-step explanation:

If the triangles are similar, it means the ratio between the two give sides is the same. As seen from the smaller triangle the ratio of the two top sides would be 16:50 or 8:25.

Since the first side of the bigger triangle (24) is three times 8 (it's ratio side), then the other side must be 3x25 = 75, which maintains the ratio 8:25 between the two sides (24:75).

Hope this helped!

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

Nicholas sent a chain letter to his friends, asking them to forward the letter to more friends. Every 12 weeks, the number of pe

Digiron [165]

Answer:

$P(t)=50(1.99)^{t/12}$

Step-by-step explanation:

The problem can be modeled by using the compound growth formula.

Given, Initial number P_0 of people who Nicholas sent the chain letter t=50

The growth rate, r =99%=0.99

Period of Growth,k =12 Weeks

$P(t)=P_0(1+r)^{t/k}$

Therefore, in any week (t) after Nicholas initially sent the mail, the number of people who receive the email is modeled by the function:

$P(t)=50(1+0.99)^{t/12}\\\\P(t)=50(1.99)^{t/12}$

Fill in the blanks on the pattern 98,97,95,92,88 ? ?

Novay_Z [31]

Answers are: 83 and 77

Notice how...
The jump from 98 to 97 is a decrease of 1
The jump from 97 to 95 is a decrease of 2
The jump from 95 to 92 is a decrease of 3
The jump from 92 to 88 is a decrease of 4

The pattern of decreases so far is: 1, 2, 3, 4

So the next decrease is 5
88-5 = 83

And the decrease after that is 6
83-6 = 77
