Answer:
35.5 cm
Step-by-step explanation:
The perimeter (P) is calculated as
P = (2 × 6.75 ) + (2 ×
)
= 13.5 + (2 × 11) = 13.5 + 22 = 35.5 cm
Answer:
a) P = 362880 ways
b) P = 2880 ways
Step-by-step explanation:
a) We have four boys and five girls, they are going to sit together in a row of 9 theater seats, without restrictions
We have a permutation of 9 elements
P = 9!
P = 9*8*7*6*5*4*3*2*1
P = 362880 ways
b) Boys must seat together, we have two groups of people
4 boys they can seat in 4! different ways
P₁ = 4!
P₁ = 4*3*2*1
P₁ = 24
And girls can seat in 5! dfferent ways
P₂ = 5!
P₂ = 5*4*3*2*1
P₂ = 120
To get total ways in the above mentioned condition, we have to multiply P₁*P₂
P = 24*120
P = 2880 ways
60 points! Because 8 questions wrong would be - 40 points and its out of 100 points so 60 points
Answer:
the mean is the sum of them all divided by the number of terms.
mean: 13
the mode is the element that occurs MOST in the data set.
mode: none
the median is the middle value of all of the numbers.
median: 9

Answer:
The decision is to <u>reject</u> the <u> null hypothesis</u> at a significant level of <u>significance </u>
There is <u>sufficient </u> evidence to conclude that <u>at least one of the population mean</u> is <u>different from</u> <u>at least of the population</u>
Step-by-step explanation:
From the question we are told that the claim is
The mean growth rates of all four species are equal.
The null hypothesis is

Th alternative hypothesis is

From question the p-value is 
And since the
so the null hypothesis will be rejected
So
The decision is to <u>reject</u> the <u> null hypothesis</u> at a significant level of <u>significance </u>
There is <u>sufficient </u> evidence to conclude that <u>at least one of the population mean</u> is <u>different from</u> <u>at least of the population</u>
