help -2 x 8/3 it's multiplecation
Answer: -16/3
Step-by-step explanation:
-2 (8/3)
(-2/1)(8/3)
((-2)(8))=-16
1(3)=3
-16/3
Answer:
-2 x 8/3 = -16/3
Step-by-step explanation:
When multiplying fractions, you multiply the numerators (numbers above the fraction line) and the denominators (numbers below the fraction line) with each other. If one of the numbers is not visibly a fraction, remember that all numbers are actually fractions - you must simply write in the denominator of 1. In this case, you'd write [tex]-\frac{2}{1} * \frac{8}{3}[/tex], which would then give you the result of [tex]-\frac{16}{3}[/tex] (-2 x 8 = -16, 1 x 3 = 3).
Hope this helped!

x²+x-90=0 using completing the square method
Answer:
x = - 10, x = 9
Step-by-step explanation:
Given
x² + x - 90 = 0 ( add 90 to both sides )
x² + x = 90
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2([tex]\frac{1}{2}[/tex] )x + [tex]\frac{1}{4}[/tex] = 90 + [tex]\frac{1}{4}[/tex]
(x + [tex]\frac{1}{2}[/tex] )² = [tex]\frac{361}{4}[/tex] ( take the square root of both sides )
x + [tex]\frac{1}{2}[/tex] = ± [tex]\sqrt{\frac{361}{4} }[/tex] = ± [tex]\frac{19}{2}[/tex] ( subtract [tex]\frac{1}{2}[/tex] from both sides )
x = - [tex]\frac{1}{2}[/tex] ± [tex]\frac{19}{2}[/tex] , thus
x = - [tex]\frac{1}{2}[/tex] - [tex]\frac{19}{2}[/tex] = [tex]\frac{-20}{2}[/tex] = - 10
x = - [tex]\frac{1}{2}[/tex] + [tex]\frac{19}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9

The cost of 24 caps is $150. Find the cost of each cap.
Answer:
6.25
Step-by-step explanation:
Divide 150 $ to 24 caps on your calculator
If the cost of 24 caps is $150, then the cost of each cap is $6.25.
What is unitary method?We know that a single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method. We typically use this technique for math calculations. We are able to locate the missing value using the unitary method.
How to solve it?Given that the cost of 24 caps is $150.
Then the cost of 1 cap is 150/24 = $6.25
Therefore we can conclude that If the cost of 24 caps is $150, then the cost of each cap is $6.25.

A random sample of 25 U.S. residents was selected using census data from the year 2000. The dotplot below shows the distribution of total personal income (in thousands) for the members of the sample. The mean of this distribution is $25,615 and the standard deviation is $25,333.What percent of the sample had total personal incomes within two standard deviations of the mean?
Answer:
95%
Step-by-step explanation:
Data falls within 2 standard deviations from the mean - is calculated using;
μ – 2σ and μ + 2σ .
The mean of this distribution is $25,615 and the standard deviation is $25,333.
μ – 2σ
= $25,615 - 2($25,333)
=$-25051
μ + 2σ
= $25,615 + 2($25,333)
= 76,281
Empirical rule states that: 95% of data falls within 2 standard deviations from the mean
Hence, 95% the sample had total personal incomes within two standard deviations of the mean.

Rewrite 2/5 : 1/20 as a unit rate.
A. 40:1
B. 5:40
C. 8:1
D. 40:5
Answer:
Your answer would be D
Step-by-step explanation:
first make 2/5 and 1/20 into ?/100
figure out how many times 5 goes into 100 than multiply 2 by that answer.
40/100=40:?
then do the same to 1/20
5/100= ?:5

The lifespans of zebras in a particular zoo are normally distributed. The average zebra lives 20.520.520, point, 5 years; the standard deviation is 3.93.93, point, 9 years. Use the empirical rule (68-95-99.7\%)(68−95−99.7%)left parenthesis, 68, minus, 95, minus, 99, point, 7, percent, right parenthesis to estimate the probability of a zebra living between 16.616.616, point, 6 and 24.424.424, point, 4 years.
Answer:
0.67894
Step-by-step explanation:
Given that :
Lifespan of zebra is normally distributed :
Mean(μ) = 20.5
Standard deviation (σ) = 3.93
Probability of Zebra living between 16. 6 to 24.4 years
Using the empirical rule :
Z = (x - μ) / σ
For : P(Z < x ) ; X = 16.6
Z = (16.6 - 20.5) / 3.93
Z = - 0.9923
P(Z < - 0.9923) = 0.16053
For : P(Z < X) ; X = 24.4
Z = (24.4 - 20.5) / 3.93
Z = 0.9923
P(Z < 0.9923) = 0.83947
Hence,
0.83947 - 0.16053 = 0.67894

Which ordered pair is a solution to the system of equations?
y=4x
y= 3x + 2
The solution of the system of equations will be (2, 8).
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
Given that;
The system of equations are,
y = 4x
And, y = 3x + 2
Now,
Solve the linear equations as;
The system of equations are,
y = 4x .... (i)
y = 3x + 2 .. (ii)
Substitute y = 4x in equation (ii) as;
y = 3x + 2
4x = 3x + 2
4x - 3x = 2
x = 2
And, y = 4x
y = 4 × 2
y = 8
