Answer:
D) 140°
Step-by-step explanation:
The total number of degrees in a triangle is 180. Since both sides of the triangle are the radius of the circle, the triangle is isosceles. Therefore the two opposite angles are equal. Thus, the central angle is 180° − 2(20°) = 140°.
Answer:
The required probability is 0.0855
Step-by-step explanation:
Consider the provided information.
The daily revenue has mean $7200 and standard deviation $1200.
The daily revenue totals for the next 30 days will be monitored.
As we know 
Substitute 
in above formula.
From the standard normal table P( Z >1.3693) = 0.0855
Hence, the required probability is 0.0855
Answer:
63 cubic inches
Step-by-step explanation:
You have to first find the volume of each mold:
6 × 4 × 2= 48 cubic inches
3 × 5 × 1= 15 cubic inches
Add these two volumes together to find the overall volume of the whole sand castle.
48+15= 63 cubic inches
Answer:
Q1 = 40
Step-by-step explanation:
Set up numbers from least to greatest
21, 40, 52, 58, 72, 75, 96
First, find the median,
Median is: 58
Now Q1 is all numbers before the median (without counting the median)
21, 40, 52
The median here is 40
Based on the angle bisector QS, the value of x is 4
<h3>How to determine the value of x?</h3>
The given parameters are:
- QS bisects <PQT
- QP and QR are opposite rays.
- m<PQT = 60
- <PQS = 4x + 14,
Because QS bisects <PQT, then
PQT = 2 * <PQS
This gives
4x + 14) * 2 = 60
Divide by 4
2x + 7 = 15
Subtract 7 from both sides
2x = 8
Divide by 2
x = 4
Hence, the value of x is 4
