Answer: the answer is 809
Step-by-step explanation:
Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
Answer:
1a. p0= 0.714
1b The result is not reasonably close to the value of 3/4 that was expected
Step-by-step explanation:
1a.Since One sample of offspring contained 376 green peas and 150 yellow peas therefore the probability of getting an offspring pea that is green will be:
Green pea/(Green pea+ Yellow pea)
p0= 376 /(376+150)
p0=376/526
Probability of getting Green pea = 0.714
1b.The result is not reasonably close to the value of 3/4 that was expected.
Answer:
Step-by-step explanation:
Use Pythagorean theorem
Hypotenuse² = base² + altitude²
= 9² + 10²
= 81 + 100
= 181
hypotenuse = √181
1.which of the following is not true for adding mixed numbers?

B.you can add mixed numbers by changing them into improper fractions or by using a number line.
C.the sum of the mixed numbers written as an improper fraction is in simplest form.
D.the sum of the mixed numbers must be written in simplest form
The answer is C
