You need to find out how many pound of dirt they put in the 1st flower bed. 5/8+2/5+3/4. 1 pound = 16 ounces so what ever you get * 16 to get how ever many ounces. I hope this helped. :)
Answer:
B, C,
Step-by-step explanation:
A - This is addition. Finding a product refers to multiplication, so this is not correct.
B - This is multiplication of 5x × 5y, exactly two factors, so this is correct.
C - This is multiplication of (x-y) × (x+y). Each equation inside the parenthesis equals one factor, so this is multiplication of exactly two factors. This answer is also correct.
D - This is multiplication of three factors, x × y × z, and is not correct.
Answer:
.
Step-by-step explanation:
The given circle has equation
.
This is the equation that has its center at the origin with radius 4 units.
When this circle is translated seven units to the right and five units up, then the center of the circle will now be at (7,5).
The equation of a circle with center (h,k) and radius r units is
.
This implies that, the translated circle will now have equation.

Answer:
Option A ( -3/2 ,
)
Step-by-step explanation:
- According to Question, The Spinner Rotate 600* Thus after Completing 360* it Comes Exactly Where It Started . Now again rotate It 180* .
- Now We Are on ( -X axis ) & Completed 360*+180*=540* Rotation
- Now After Rotate It 60* More we come in Third Quadrant & Here In Third Quadrant Only Tangent & Cotangent Is Positive .(Sine & Cosine is Negative)
(For Diagram, Please Find in attachment)
Now In Triangle OAB
1/2 = -X / 3 Thus X= -3/2
/2 = -Y / 3 Thus Y = -
* 3 /2
Using the z-distribution, a sample size of 180 is needed for the estimate.
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:

The margin of error is given by:

In which:
is the sample mean.
is the standard deviation for the population.
In this problem, we have a 98% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 2.327.
The population standard deviation is of
, and to find the sample size, we have to solve for n when M = 4.
Hence:





n = 179.03.
Rounding up, as a sample size of 179 would result in an error slightly above 4, a sample of 180 is needed.
