Ok bet I got you say less
Answer:
(a)z=-1
(b)48.5 pounds
(c)61.5 pounds
Step-by-step explanation:
Given:
Mean, μ = 55 pounds
Standard deviation,σ = 6 pounds.
(a)For a dog that weighs 49 pounds.
x=49 pounds
The z-score
(b)When a dog has a z-score of -1.09
The weight of a dog with a z-score of -1.09 is 48.5 pounds.
(c)When a dog has a z-score of 1.09
The weight of a dog with a z-score of 1.09 is 61.5 pounds.
Answer:
20
Step-by-step explanation:
I assume y is 4/3 of z.
x = 7/6 y
y = 48
x = 7/6 * 48
x = 7 * 8
x = 56
y = 4/3 z
4/3 z = y
z = 3/4 y
z = 3/4 * 48
z = 36
x - z = 56 - 36 = 20
Answer:
The answer is 2.67
Step-by-step explanation:
AB = 3
BD = 2
AC = 4
BD and DE are parallel, AB/BD= AC/CE
3/2 = 4/CE
CE= 4*2/3
CE=8/3
Lastly, if you put it into decimal form, it is 2.67
First of all, Jamie's room is really weird. Second of all, let's solve. Since the formula for the area of a circle is (pi)r^2, and Jamie's room is exactly half of that, the area for a semicircle would be (1/2)(pi)r^2. The straight wall is the diameter, so half of the diameter would be the radius. Half of 14 is 7. Now, you rewrite the equation and substitute the values of the variables. The new equation (if you're using 3.14 for pi) is (1/2)(3.14)(7^2), or (1/2)(3.14)(49). From here you can solve, so the answer would be 76.93. Jamie needs 76.93 square feet of carpet.
