If you add the standard deviation to the average, it is 14.84. Because Marcus's score was lower than that, he will not receive a certificate.
I think this should be right for the reason and the calculation.
Answer:
check on google but it might be -10
Step-by-step explanation:
He could plot coordinates and find the slope and y intercepts of the solutions
Given: =
Awnser: tan theta 15/8.
Step-by-step explanation:
AC = 17
AB = 15
BC = ?
By Pythagoras theorem:
AC² = AB² + BC²
17² = 15² + BC²
289 = 225 + BC²
BC² = 289 – 225
BC² = 64
BC = √64
BC = 8
The value of tanθ = 15/8
You can also approach it this way:
28 flowers times n = 3444
so n = 123
11 x 123 = roses, 17 x 123 = tulips.
Those 2 products should add up to 3444.
