Divide. Round your answer to the nearest whole number.
In the following triangle what is the length of the hypotenuse?
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

59,61,61,72,80 what is the median of the data?
Answer:
61
Step-by-step explanation:
median mean the middle number (number that appears to be in the middle)
you were given a series of numbers, like in this question is quite easy because you were given five numbers. so you cancel out two from the left and two from your right the remainder is 61 and that's your median.

Anthony currently earns $11.75 per hour.
• He will get a $0.25 raise after 6 months.
• He will get a 2.5% raise after an additional 6 months.
After Anthony gets both raises, what will his pay be for 38 hours of work?
Answer:
$467.40
Step-by-step explanation:
well if you take his original pay (11.75) and add 0.25, you get 12.00 per hour.
12.00 + 2.5% raise would be:
12.00 + 0.3 or 30 cents, so the pay per hour is 12.30.
then take 12.30 x 38 and you should get $467.40
so after both raises, and 38 hours of work, he will earn $467.40

2(x+3) = 5x+10 - x
Explain your reasoning
Answer:
x= -2
Step-by-step explanation:
2(x+3)=5x+10-x (we need to distribute first)
2x+6=4x+10 (then add like terms)
-2x=4 (now divide)
x= -2

In a scale drawing of a painting, 1 centimeter represents 7 inches
Scale
1 cm : 7 in
Answer the following.
(a) The height of the real painting is 28 inches. What is the
height of the painting in the scale drawing?
(b) In the scale drawing, the length of the painting is 9
centimeters. What is the length of the real painting?
A) divide actual inches by scale:
28/7 =4 cm
B) multiply actual cm by scale:
9 x 7 = 63 inches
It is claimed that 95% of teenagers who have a cell phone never leave home without it. To investigate this claim, a random sample of 300 teenagers who have a cell phone was selected. It was discovered that 273 of the teenagers in the sample never leave home without their cell phone. One question of interest is whether the data provide convincing evidence that the true proportion of teenagers who never leave home without a cell phone is less than 95%. What are the values of the test statistic and P-value for this test?
Answer:
B. z = –3.18, P-value = 0.0007

Dogs vary in size a great deal more than cats do. Suppose the mean weight of dogs in a certain city is 28 pounds with a standard deviation of 14 pounds, and the mean weights of cats is 9.5 pounds with a standard deviation of 2 pounds. Cat weights are roughly Normally distributed, but dog weights are skewed right. Suppose you take a random sample of 10 dogs and 8 cats. 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?
a. Mean = 18.5 pounds, standard deviation = 4.48 pounds, shape approximately Normal
b. Mean = 18.5 pounds, standard deviation = 4.48 pounds, shape non-Normal
c. Mean = 18.5 pounds, standard deviation - 14.1 pounds, shape approximately Normal
d. Mean = 18.5 pounds, standard deviation = 14.1 pounds, shape non-Normal
e. The difference of means is 18.5 pounds and the shape is non-Normal, but the standard deviation cannot be determined since the sample size is small and the distribution of dog weights is non-Normal.
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.
