Answer:

Hypotenuse: 6

Step-by-step explanation:

Sin45°=(BC/AC)

Sin45°=(3√2/AC

1/√2=3√2/AC

AC=3×2=6

so hypotenuse = 6

hope it helps

have a great day!!

Answer:

6

Step-by-step explanation:

here's your solution

=> sin 45° = perpendicular/hypotenuse

=> sin 45° = 1/√2

=> perpendicular = 3√2

=> 1/√2 = 3√2/hypotenuse

=> Hypotenuse = 3*√2*√2

=> Hypotenuse = 3*2

=>. Hypotenuse = 6

Answer:

6,8,10 is the pythagoran triplet

Answer:

6 8 10

Step-by-step explanation:

Well, the most known known Pythagorean triplet ever is 3 4 5.

Fortunately, if we scale it by 2:1, we'll get a Pythagorean triplet containing 6.

Answer:

6². is 64

4 + 2 is 6

64 - 6

is 58

Answer:

Steps:

6² - 4 + 2 = 36 - 4 + 2 (exponents first 6²=36)

(subtraction and addition have the same degree! so we do whichever one comes first! "order")

6² - 4 + 2 = 32 + 2

6² - 4 + 2 = 34

Answer:

80 different points.

Step-by-step explanation:

right, left, up, or down = 4 possibilities x 2 since there is a coordinate with 2 numbers so,

8 possibilities.

8 x 10 = 80 possibilities.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. After $10 steps, the number of different points that could Franklin ends up at 1048576.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that Franklin can move in 4 direction after each step, therefore, the number of choices that Franklin have is,

Number of points = 4×4×4×4×4×4×4×4×4×4 = 4¹⁰ = 1048576

Hence, After $10 steps, the number of different points that could Franklin ends up at 1048576.

Answer:

3.35 = (3 * 100) + (3 * 1/101) + (5 * 1/102)

3.35 = (3 * 1) + (3 * 1/10) + (5 * 1/100)

3.35 = 3 + 3/10 + 5/100

3.35 = 3 + 0.3 + 0.05

Answer:

The formula for the volume of a sphere is V = 4/3 πr³.  

Step-by-step explanation:

Surface area of sphere = 4πr2

Volume of a sphere = 4/3 πr3

You only need to know the radius to figure both the volume and surface area of a sphere.

Answers for surface area problems should always be in square units.

Answers for volume problems should always be in cubic units.

Answer:

H.

Step-by-step explanation:

I believe this is the answer because when you look at the problem and see the rate of change pattern months go +2 , +3, +2, and +3. Then when you look at the cards rate of change 80-44=36, so +36 then 104-80=24, so +24. as you can see when you subtract the rates if change between the cards (36-24), you get 12. Therefore y=12x. next you go along with the pattern and find the y-intercept by doing 44-24=20. Sorry it is kinda hard to explain, but hope this helps!

Allen was given 20 cards , and he buys 12 cards each month

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Let the number of cards be y

Let the number of months be x

Let the first point be P ( 5 , 80 )

Let the second point be Q ( 7 , 104 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 104 - 80 ) / ( 7 - 5 )

m = 24 / 2

m = 12 cards per month

So , the equation of line is y - y₁ = m ( x - x₁ )

y - 80 = 12 ( x - 5 )

Adding 80 on both sides , we get

y = 12x + 20

So , when x = 0

y = 20 cards in the initial month

Hence , the equation of line is y = 12x + 20 and Allen has 20 cards in his initial month

Answer:

b. Mean = 18.5 pounds, standard deviation = 4.48 pounds, shape non-Normal

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

Subtraction of samples:

When two samples are subtracted, we have that the mean is the difference between the means and the standard deviation is the square root of the sum of the variances.

The mean weight of dogs in a certain city is 28 pounds with a standard deviation of 14 pounds. Sample of 10

This means that [tex]\mu_{D} = 28, s_D = \frac{14}{\sqrt{10}} = 4.4272[/tex]

Mean weights of cats is 9.5 pounds with a standard deviation of 2 pounds. Sample of 8.

This means that [tex]\mu_{C} = 9.5, s_{C} = \frac{2}{\sqrt{8}} = 0.7071[/tex]

Which of the following is an accurate description of the center, spread, and shape of the sampling distribution of the difference in the mean weight dogs and the mean weight of cats?

The mean is:

[tex]\mu = \mu_{D} - \mu_{C} = 28 - 9.5 = 18.5[/tex]

The standard deviation(spread) is:

[tex]s = \sqrt{s_{D}^2+s_{C}^2} = \sqrt{4.4272^2+0.7071^2} = 4.48[/tex]

Normal distribution subtracted by non-normal(sample of cats is less than 30, so wont be normal), will be non-normal.

The correct answer is given by option b.
