Bill bought a tv for 379.99 there was a discount of 20% local tax is 3% and state tax is 6% how much did bill pay for the tv
Answer:
331.35
Step-by-step explanation:
The tax rates are added together for a final tax rate of 3% +6% = 9%. After the discount, Bill pays 80% of the marked price. The added tax multiplies that cost by 109%. Bill pays ...
379.99(0.80)(1.09) = 331.35
Bill paid 331.35 for the TV.
What is the probability of tossing a coin three times and getting heads
each time? *
Answer:
probability of tossing a coin 3 times and getting heads each time is 1/8
Step-by-step explanation:
A coin has 2 sides (heads and tails) therefore you have a 50% chance of getting either heads or tails for each toss. Therefore, the probability of getting heads for 1 toss is 1/2. Now, tossing it 3 times and getting heads each time essentially means you would have to do (1/2)×(1/2)×(1/2) which would give you 1/8 as the probability of tossing a coin 3 times and getting heads each time.
The volume of the cube is 512 cubic inches. Find the side length of the cube.
Answer:
128
Step-by-step explanation:
512/4
Answer:
a = 8 cm, as cube root of 512 is 8. The side lengths (edges) are 8 cm.
Step-by-step explantation
8 cubic feet = 2 feet 512 cubic feet.
First you Multiply your length, width and height figures together, giving you a total in cubic inches (in3)Divide the total by 512 (as there are 512 cubic inches in a cubic foot) it equals to 8 meaning your answer is correct. I f not it wrong and I already look this this up its 8
Use z scores to compare the given values.
Based on sample data, newborn males have weights with a mean of 3259.8 g and a standard deviation of 869.7 g. Newborn females have weights with a mean of 3000.9 g and a standard deviation of 550.8 g. Who has the weight that is more extreme relative to the group from which they came: a male who weighs 1600 g or a female who weighs 1600 g?
Since the z score for the male is z=__and the z score for the female is z=___, the
(male or female(which one)has the weight that is more extreme.
Answer:
The answer is given below
Step-by-step explanation:
Z score is used to measure by how many standard deviations the raw score is above or below the mean. It is given by the formula:
[tex]z=\frac{x-\mu}{\sigma}\\ \\Where\ \mu=mean, x=raw\ score, \sigma=standard\ deviation[/tex]
For the male:
μ = 3259.8 g, σ = 869.7 g
Hence for a male who weighs 1600 g, the z score is:
[tex]z=\frac{x-\mu}{\sigma} =\frac{1600-3259.8}{869.7}=-1.91[/tex]
For the female:
μ = 3000.9 g, σ = 550.8 g
Hence for a female who weighs 1600 g, the z score is:
[tex]z=\frac{x-\mu}{\sigma} =\frac{1600-3000.9}{550.8}=-2.54[/tex]
Since the z score for the male is z= -1.91 and the z score for the female is z= -2.54 the male has the weight that is more extreme.

can anyone solve this please it is urgent..??
Answer:
Step-by-step explanation:
Q4 NO 1
x-5+3x+x+65= 180 degrees
x+3x+x+65-5= 180 degrees
5x+60= 180 degrees
5x=180-60
5x= 120
Divide both sides by 5
x=24
Q4 NO 2
5y-20+y+200= 360 degrees
5y+y+200+20= 360 degrees
6y+220= 360 degrees
6y= 360-220
6y=180 degrees
Divide both sides by 6
y= 30 degrees

what is the distance between ( 0,5 ) , ( -3,-4)
Answer:
The distance between the points (6,-4) and (0,5) = 10.82 units
Step-by-step explanation:
Distance formula
Length of a line segment with end points (x1, y1) and (x2, y2) is given by,
Distance = √[(x2 - x1)² + (y2 - y1)²]
To find the distance between given points
Here, (x1, y1) = (6, -4) and (x2, y2) = (0, 5)
Distance = √[(x2 - x1)² + (y2 - y1)²]
= √[(0 - 6)² + (5 - -4)²]
=√[(-6)² + (9)²]
= √[36 + 81]
= √[117
= 10.82
The distance between the points (6,-4) and (0,5) = 10.82 units

Since f(x, y) = 1 + y2 and ∂f/∂y = 2y are continuous everywhere, the region R in Theorem 1.2.1 can be taken to be the entire xy-plane. Use the family of solutions in part (a) to find an explicit solution of the first-order initial-value problem y' = 1 + y2, y(0) = 0. y = Even though x0 = 0 is in the interval (−2, 2), explain why the solution is not defined on this interval. Since tan(x) is discontinuous at x = ± , the solution is not defined on (−2, 2).
