You can use trigonometry specially the cos rule in this case. I can’t send the other pictures. But using the cos rule you can check whether the angle is 90
10 inches because there are 4 sides of a square so, if the perimeter is 40 inches, to figure out the side lengths you just have to divide the perimeter by 4
Answer: Gary needs to work more than 25hours for the week to earn above $400.
Step-by-step explanation:
For Gary to be paid $50 per week means he worked $50/ $15.50= 3.23 hours for the week.
To make over $400 this week he needs to work for
400/15.50 = 25.81 hours and more for the week to earn above $400
Answer:
The sum of the probabilities is greater than 100%; and the distribution is too uniform to be a normal distribution.
Step-by-step explanation:
The sum of the probabilities of a distribution should be 100%. When you add the probabilities of this distribution together, you have
22+24+21+26+28 = 46+21+26+28 = 67+26+28 = 93+28 = 121
This is more than 100%, which is a flaw with the results.
A normal distribution is a bell-shaped distribution. Graphing the probabilities for this distribution, we would have a bar up to 22; a bar to 24; a bar to 21; a bar to 26; and bar to 28.
The bars would not create a bell-shaped curve; thus this is not a normal distribution.
