Find the distance between the two points rounding to the nearest tenth (8,7) and (1,-2)
Answer:
11
Step-by-step explanation:
The distance between them can be calculated using Distance Formula , the points here are (8,7) and (1,-2) . Using Distance Formula we have ,
⇒ D = √ [ (x_2 - x_1)² + (y_2 - y_1)² ]
⇒ D = √ [ (8-1)² + (7+2)² ]
⇒ D = √ [ 7² + 9² ]
⇒ D = √ [ 49 + 81 ]
⇒ D = √ 130
⇒ D = 11.401 units
Rounding off we have , 11.401 ≈ 11 units .

4.78 times 10 to the 6th power was the largest attendance record of the polar bear express. chilly football extravaganza. 3.98 times 10 to the 6th power attended at the last last pb express event. how many more people were in attendance on the record-setting day?
9514 1404 393
Answer:
8×10⁵ = 800,000
Step-by-step explanation:
The difference is ...
(4.78×10⁶) -(3.98×10⁶) = 0.80×10⁶ = 8×10⁵
8×10⁵ = 800,000 more people attended at the largest extravaganza.

The probability of being a universal donor is 6% (O-negative-blood type). Suppose that 6 people come to a blood drive.
a) What are the mean and standard deviation of the number of universal donors among the 6 people?
b) What is the probability that there are exactly three universal donors?
Using the binomial distribution, it is found that:
a) The mean is of 0.36 and the standard deviation is of 0.58.
b) There is a 0.0036 = 0.36% probability that there are exactly three universal donors.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.The expected value of the binomial distribution is:
E(X) = np
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
The values of the parameters are given as follows:
n = 6, p = 0.06.
Item a:
E(X) = np = 6 x 0.06 = 0.36.[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{6 \times 0.06 \times 0.94} = 0.58[/tex]The mean is of 0.36 and the standard deviation is of 0.58.
Item b:
The probability is P(X = 3), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{6,3}.(0.06)^{3}.(0.94)^{3} = 0.0036[/tex]
There is a 0.0036 = 0.36% probability that there are exactly three universal donors.

. Eado fime Blend buys lunch at school, the balance on her school lunch account changes
by 53. Last month, Eiend's balance changed by-536 in all. She wants to know how
many times she bought lunch last month
Which expression represents the number of times
Een bought lunch last month?
- 36 - 3
-263
No LINKS
Answer:
-36 ÷ -3
Step-by-step explanation:
Change in her school lunch account balance per lunch = -3
Total change in her school lunch balance last month = -36
Expression to show number of times Elena bought lunch last month = Total change in her school lunch balance last month ÷ Change in her school lunch account balance per lunch
= -36 ÷ -3
= -36/-3
= 12 times
Elena bought lunch 12 times last month
Alan Bissell, market analyst for City Sound Mart, is analyzing the relation between heavy metal CD sales and the size of the teenage population. He gathers data from six sales districts. Alan's dependent variable is annual heavy metal CD sales (in $1,000,000's), and his independent variable is teenage population (in 1,000's). Regression analysis of the data yielded the following tables. For a sales district with 20,000 teenagers, Alan's model predicts annual CD sales of ________________.
Answer:
0.105195x - 0.14156
Step-by-step explanation:
The relationship between heavy metal CD sales and size of teenage population is to be obtained. The attached table shows the result obtained from a regression analysis.
The dependent variable, which is the predicted value or variable, y = heavy metal yield
The Independent variable, predictor variable, x = heavy metal yield
Feommthe table ;
Coefficient of x = slope 0.105195
Intercept = - 0.14156
The general form of a simple linear regression model is :
y = mx + c
c = intercept ; m = slope
Therefore, we have the model :
y = 0.105195x - 0.14156

• A cylindrical tank can hold 2279.64 cubic feet of water. The radius of the tank is 11 feet. What is the height of the tank?
Answer:
Step-by-step explanation:
so you want to know the formula for the volume of a cylinder
volume (cylinder) = area of the circular base * height
2279.64 = area of a circle + height
area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]
they tell us the radius is 11 feet so r = 11
circle = [tex]\pi[/tex][tex]11^{2}[/tex] = 38013271
2279.64 = 38013271 * height
2279.64 / 38013271 = height
5.996958 = height in feet

Find the length of AB?
Given:
The figure of a right triangle.
To find:
The length of AB.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
Using this trigonometric ratio for the given triangle, we get
[tex]\cos A=\dfrac{AB}{AC}[/tex]
[tex]\cos (60^\circ)=\dfrac{AB}{10}[/tex]
[tex]\dfrac{1}{2}=\dfrac{AB}{10}[/tex]
[tex]\dfrac{1}{2}\times 10=AB[/tex]
[tex]5=AB[/tex]
Therefore, the length of AB is 5 units.
