Okay so we know that 3/5 of the conductors club went on the last camping trip. We also know that 3/5 of the club is equal to 39 people. All we have to do is find the last 2/5 and add it to our 3/5 to get the answer:
To find how much each 1/5 is, divide 39 by 3. This will give us 13. Then we multiply it by 5, because there are five parts. This gives us 65. So the answer is 65
Answer:
21 is the answer my guy
Step-by-step explanation:
7 times 3 is 21
Answer: 3/4x - 3
Step-by-step explanation:
Let his sister's sale be represented by x.
Since we are informed that Keiko sold 3 less than three-fourths of his sister's sales, the expression that represents what Keiko sold will be:
= (3/4 × x) - 3
= 3/4x - 3
Answer:
Step-by-step explanation:
For the null hypothesis,
H0: p = 88
For the alternative hypothesis,
Ha: p < 88
Considering the population proportion, probability of success, p = 0.88
q = probability of failure = 1 - p
q = 1 - 0.88 = 0.12
Considering the sample,
Sample proportion, P = x/n
Where
x = number of success = 21
n = number of samples = 32
P = 21/32 = 0.66
We would determine the test statistic which is the z score
z = (P - p)/√pq/n
z = (0.66 - 0.88)/√(0.88 × 0.12)/32 = - 3.83
The corresponding p value would be determined by looking at the normal distribution table for the area below the z score. Therefore,
P value = 0.00006
