To determine whether or not they have a certain desease, 304 people are to have their blood tested. However, rather than testing

Artyom0805 [142]

Answer:

The expected number of tests necessary for the entire group of 304 people is 180.0325

Step-by-step explanation:

Probability of person being positive = p = 0.04

Probability of person being negative = q = 1-0.04=0.96

Number of people in each group = 19

We will use binomial over here

Probability of no test positive :

$P(x=0) = ^{19}C_0 (0.04)^0 (0.96)^{19} =0.460419201958$

P( at least one tests positive) = 1-P( no one tests positive)= 1-0.460419201958= 0.539580798042

Expected number of tests for each group = 1(0.460419201958)+20(0.539580798042) = 11.2520351628

Number of groups = $\frac{\text{Total population}}{\text{no. of people in each group}}=\frac{304}{19}=16$

Expected number of tests necessary for the entire group of 304 people:

= $\text{Expected number of tests for each group} \times \text{No. of groups}$

= $11.2520351628 \times 16$

=180.0325

Hence The expected number of tests necessary for the entire group of 304 people is 180.0325

GEOMETRY HELP PLS ALMOST DONE THANK U

lana [24]

Answer:

y = 4

Step-by-step explanation:

Since this is an equilateral triangle, all the sides are equal.

7y + 5 = 9y - 3

5 + 3 = 9y - 7y

2y = 8

y = 8 ÷ 2

y = 4
