Answer:
the answer is 7
Step-by-step explanation:
the right angle is 90°
90-55=35
35÷5=7
Answer:
1/18
Step-by-step explanation:
there are 12 marbles in the bag
P(choose red) = 2/12 = 1/6
P(choose blue after replacement) = 4/12 = 1/3
P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18
Answer:
200 feet
Step-by-step explanation:
If it raises 100 feet in 4 minutes then times the 4 by 2 and get 200
Plz give brainliest
100 times 2 equals 200 because 4 times 2 equals 8

the least number of weeks is 
Step-by-step explanation:
Let
x-------> the number of weeks
we know that
The inequality that represent the situation is

solve for x
Divide by
both sides


therefore
the least number of weeks is 
Answer:
a
The 95% confidence interval is
b
The result obtained does not contradict expectation
Step-by-step explanation:
From the question we are told that
The number of green peas is k = 438
The number of yellow peas is u = 173
Generally the sample size is mathematically represented as

=>
=> 
Generally the sample proportion for yellow peas is

=> 
=> 
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the margin of error is mathematically represented as
=>
=>
Generally 95% confidence interval is mathematically represented as
=>
=>
From the question we are told that it was expected that 25% of the offspring peas will be yellow
Now from the 95% confidence interval obtained we see that the expected sample proportion(25% ) falls within it so it means that the result obtained does not contradict expectation
