Asurvey was conducted among 78 patients admitted to a hospital cardiac unit during a two-week period. the data of the survey are shown below. let b equals the set of patients with high blood pressure. let c equals the set of patients with high cholesterol levels. let s equals the set of patients who smoke cigarettes. n(b) equals 36 n(b intersect s) equals 10 n(c) equals 34 n(b intersect c) equals 12 n(s) equals 30 n(b intersect c intersects) equals 5 n[(b intersect c) union (b intersect s) union (c intersect s)] equals 21

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
