A set of average city temperatures in May are normally distributed with a mean of 20.66 ^\circ \text{C}20.66
∘
C20, point, 66, degrees, start text, C, end text and a standard deviation of 2 ^\circ \text{C}2
∘
C2, degrees, start text, C, end text. The average temperature of Singapore is 26 ^\circ \text{C}26
∘
C26, degrees, start text, C, end text.
What proportion of average city temperatures are lower than that of Singapore?
You may round your answer to four decimal places.
Answer:
0.9962
Step-by-step explanation:
The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma}\\ \\\mu=mean,\sigma=standard\ deviation, x=raw\ score[/tex]
μ = 20.66°C, σ = 2°C
For x < Singapore temperature, i.e. x < 26
[tex]z=\frac{x-\mu}{\sigma} =\frac{26-20.66}{2}=2.67[/tex]
From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962

Find roots (zeroes) of : F(x) = 5x3+x2-32
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 5 and the Trailing Constant is -32.
The factor(s) are:
of the Leading Coefficient : 1,5
of the Trailing Constant : 1 ,2 ,4 ,8 ,16 ,32
Let us test ....

Please help me please I feel like crying cause I can't do it...
Answer:
1. 39
2. 15
3.329
4. 16
5. 300
Step-by-step explanation:
Just divide the first two numbers and then multiply the quotient by the last number. You'll be ok, you've got this, keep your head up!
1. 52/4 = 13 and 13 x 3 = 39
2. 45/9 = 5 and 5 x 3 = 15
3. 470/10 = 47 and 47 x 7 = 329
4. 10/2.5 = 4 and 4 x 4 = 16
5. 125/2.5 = 50 and 50 x 6 = 300
If the triangles are similar, then the value of x is (blank) and the value of y is (blank)
I REALLY NEED HELP PLZZZ
Answer:
([tex]x[/tex], [tex]y[/tex]) = (30, 16)
Step-by-step explanation:
First find the similarity
Since you know the legnth of the hypotenuse (the longest one) for both traingles, you can find the similarity by dividing the longer by the shorter:
50 ÷ 20 = 2.5
The similarity between the 2 triangles is 2.5.
Now find the length of [tex]x[/tex] on the longer one, use the shorter one's length and the similarity:
12 × 2.5 = 30
So the length of [tex]x[/tex] is equal to 30
Now lets find [tex]y[/tex], lets use the length of the larger triangle this time and divide the length of the longer leg (there are 2 legs in every triangle, if you don't know the hypotenus's length, use the pythagorean theorem) and divide it by the similarity:
40 ÷ 2.5 = 16
[tex]y[/tex] = 16
WooHoo! ([tex]x[/tex], [tex]y[/tex]) = (30, 16)

Jason had one hundred fifty-nine dollars to spend six books.After buying them he had fifteen dollars.How much did each book cost.
Answer:
11.5
Step-by-step explanation:
Divide: 159:6-15
Calculate: 26.5-15
\\11.5//
Answer:
24.8333 with 3 repeating.
Step-by-step explanation:
Lets make an equation for this.
159 - x = 15
X is what we are loooking for so lets isolate it.
Subtract 159 on both sides.
-x = -149
Since both are negative we need to simply cross it out.
x = 149
Now he bought six books, so divide 149 by 6.
You would get 24.8333 with the 3 repeating.

y=-3x-1 find slope and y interceapt
Slope = - 3
y-int = - 1
Step-by-step explanation:Understanding slope intercept
y = mx + b
y = Slope(x) + y-intercept
y = -3x - 1
y = (-3)x + (-1)
Slope = - 3
y-int = - 1

What is the sales tax on a $14,500 truck if the tax rate is 9%. What is the total price of the truck
after the sale tax?
Answer:
in order to find percentages you have to multiply the base cost by the tax and then divide it by 100
Step-by-step explanation:
base price is 14500
tax rate is 9 percent
(14500 × 9 ) ÷ 100
or you can just do this
14500 × 0.09 = 1305
since multiplying by 9 then dividing by 100 is equal to multiplying by 0.09 (9/100)
14500+1305= 15805
Which linear function represents the line given by the point-slope equation y + 7= -2/3 (x+6)
A) f(x) = -2/3x – 11
B) f(x) = -2/3x -1
C) f(x) = -2/3 + 3
D) f(x) = -2/3 + 13
[tex]y + 7 = - \frac{2}{3}(x + 6) \\ [/tex]
[tex]y + 7 = - \frac{2}{3}x - 4 \\ [/tex]
Subtract sides -7
[tex]y = - \frac{2}{3}x - 4 - 7 \\ [/tex]
Thus ;
[tex]y = f(x)= - \frac{2}{3}x - 11 \\ [/tex]
So the correct answer is (( A )) .

State whether the data described below are discrete or continuous, and explain why.
- The exact heights of different elephants. Choose the correct answer below.
A. The data are continuous because the data can take on any value in an interval.
B. The data are discrete because the data can only take on specific values.
C. The data are continuous because the data can only take on specific values.
D. The data are discrete because the data can take on any value in an interval.
Answer:
The correct answer:
The data are continuous because the data can take on any value in an interval. (A)
Step-by-step explanation:
There are two categories of data:
Discrete data: These are data that have specific values that they can take on. There are limits to what values can be assigned to such categories. for example, The number of countries in a continent, there can either be 15 countries, 50 countries 30 countries, etc. There is not a possibility of having 40.56 countries on this kind of list. hence it is a discrete dataset.
Continuous data are data that can take on any value within an interval or on a particular scale of measurement. In this example, the height of the elephant in meters can be 1.5m, 2m, 1.06m, etc. There is no limit to the possibility of the height of an elephant on a meter scale.

James has $40 to spend. He wants to buy 2 tickets to a show. He has to spend $7 to get where tickets are sold. The following inequality can be used to find out the highest price James can afford to pay for each ticket. 2x+7 less than or equal to 40.
A.) x less than or equal to 23.5
B.) x less than or equal to 16.5
C.) x greater than or equal to 23.5
D.) x greater than or equal to 16.5
Answer:
B.) X less than or equal to 16.5
Step-by-step explanation:
If you take his limit, 40 and subtract the 7 dollars you will get 33. Then, divide that by two because he will need two tickets and you will get 16.5. It can't be greater than 16.5 because he will go over his budget.
Answer:
x ≤ 16.5
Step-by-step explanation:
40 ≤ 2t + 7 Subtract 7 from both sides.
40 - 7 ≤ 2t + 7 - 7
33 ≤ 2t Divide both sides by 2.
[tex]\frac{33}{2}[/tex] ≤ [tex]\frac{2t}{2}[/tex]
16.5 ≤ t or t ≥ 16.5
