d is the answer and srry if im too laate
Answer:
see explanation
Step-by-step explanation:
step 4 take the square root of both sides
= ± ![\sqrt{11}](https://tex.z-dn.net/?f=%5Csqrt%7B11%7D)
x + 4 = ± ![\sqrt{11}](https://tex.z-dn.net/?f=%5Csqrt%7B11%7D)
step 5 subtract 4 from both sides
x = - 4 ± ![\sqrt{11}](https://tex.z-dn.net/?f=%5Csqrt%7B11%7D)
step 6 solve for x
x = - 4 -
or x = - 4 + ![\sqrt{11}](https://tex.z-dn.net/?f=%5Csqrt%7B11%7D)
Answer:
Similar triangle means that only the angles are the same, but the sides are not. Congruent means the angles and sides are the same.
Answer:
sorry only doing the ones i know how to do
b) for the histogram, just write all the numbers on the table on the bottom, theres 13 lines but 2 repeats so it should be even. on the side write a range of minutes
c) mean = 7.8 ; standard deviation = 3.13
d)
min = 2
max = 13
range = 11
q1 = 5.5
q3 = 10.75
iqr = 5.25
median = 8
what does iqr represent? it represents the middle 50% of all the values
e) write the numbers from the table without repeats and mark them how many times theyre written
