Step-by-step explanation:
CI = p ± z √(pq/n)
For 90% confidence, z = 1.645.
CI = 0.55 ± 1.645√(0.55 × 0.45 / 64)
Answer:
80
Step-by-step explanation:
ramans ratio is 2:3
so in 150ml there are 2 parts of juice and 3 parts of water
2x + 3x = 150
x = 30
so, juice in 150 ml of raman's mixture = 2x = 2* 30 = 60ml
meera ratio is 1:4
similarly,
1y + 4y = 100
y = 20
so, juice in 100 ml of meera's mixture is y = 20ml
so, quanitity of juice in final mixture is 60 + 20 = 80

Answer:
If Connor makes x dollars in sales, he will make 0.05x + 300 that week.
He makes $408.75 in a week if he makes $2175 in sales.
