5 days a week
9 hours a day
there are 52 weeks which means he works 260 days and 2340 hours a year
divide 29000 by 2340 and u get 12.4 per hour
Answer:
Scalene
Step-by-step explanation:
With this question, it's best to draw it out or we can use process of elimination.
We can rule out Right as the triangle is already obtuse (it can't be both).
We can rule out Equilateral as all the sides are not equal.
We can also rule out Isosceles as this triangle requires 2 sides to be equal, which clearly, they aren't.
Therefore, we are left with Scalene (C) which is your answer.
A scalene triangle has no identical sides or angles, and can be obtuse, right or acute.
Hope this helps,

Answer:
a14 = -40,960
Step-by-step explanation:
The sequence has a first term of 5 and a common ratio of -10/5 = -2, so the n-th term is given by ...
an = a1·r^(n-1)
an = 5·(-2)^(n-1)
The 14th term is then ...
a14 = 5·(-2)^(14-1) = -5·2^13 = -5·8192
a14 = -40,960
Answer:
a) r = 0.974
b) Critical value = 0.602
Step-by-step explanation:
Given - Two separate tests are designed to measure a student's ability to solve problems. Several students are randomly selected to take both test and the results are give below
Test A | 64 48 51 59 60 43 41 42 35 50 45
Test B | 91 68 80 92 91 67 65 67 56 78 71
To find - (a) What is the value of the linear coefficient r ?
(b) Assuming a 0.05 level of significance, what is the critical value ?
Proof -
A)
r = 0.974
B)
Critical Values for the Correlation Coefficient
n alpha = .05 alpha = .01
4 0.95 0.99
5 0.878 0.959
6 0.811 0.917
7 0.754 0.875
8 0.707 0.834
9 0.666 0.798
10 0.632 0.765
11 0.602 0.735
12 0.576 0.708
13 0.553 0.684
14 0.532 0.661
So,
Critical r = 0.602 for n = 11 and alpha = 0.05
