Answer:
いちまんいっせん
Step-by-step explanation:
Part A is y=2x+5
I’m not sure if you need help with part b but I can’t fully see the question.
The answer is C 23. The problem says that "the mean number of days of the sample" is outside the confidence interval. The mean number of days of the sample is equal to 23. If 23 is outside the confidence interval, this is probably not the mean number of days that the company's air fresheners last.
Well, you need to add together how much wood you need. one side is 4 1/4 long & the other side is 5 1/8 long. you need to find a common denominator before you add.
multiply the numerator and denominator of the first number by 2.
4 1/4 × 2 = 4 2/8
multiply the numerator and denominator of the second number by 1 because you already have common denominators.
5 1/8 × 1 = 5 1/8
now you can add.
4 2/8 + 5 1/8 = 9 3/8
9 3/8 does not simplify.
therefore Mrs. Edwards only needs to buy the smallest amount of wood available, which is 12 inches.
It’s a median of 9 sorry if I’m wrong
