- 5/6 + (-2/3) = what

Answer: In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer: PLEASE READ: The coefficients of (x + y)n are given by the nth row of Pascal's triangle. To generate Pascal's triangle, add adjacent terms on a row to determine the term directly below them. Each row is a "palindrome"- that is, it is the same if read from left to right or from right to left.

Answer:

(1) 56 miles/hour

Step-by-step explanation:

We need to find the average rate of change from t = 2 to t = 9.

At t = 2 hours, d = 106 miles.

At t = 9 hours, d = 498 miles.

The average rate of change in function f(x) from x = a to x = b is

[f(b) - f(a)]/(b - a)

average rate of change from t = 2 to t = 9 =

(498 - 106)/(9 - 2) = 392/7 = 56

Answer: (1) 56 miles/hour

Answer:

The decision rule is  

Fail to reject the null hypothesis

 The conclusion is  

There is no sufficient evidence to show that  the  designer's claim of a better shoe is supported by the trial results.

Step-by-step explanation:

From the question we are told that

  The population mean is  [tex]\mu = 15 \ months[/tex]

   The sample size is  n =  25

   The sample mean is  [tex]\= x = 17 \ months[/tex]

   The standard deviation is  [tex]s = 5.5 \ months[/tex]

Let assume the level of significance of this test is  [tex]\alpha = 0.05[/tex]

    The null hypothesis is  [tex]H_o : \mu = 15[/tex]

     The alternative hypothesis is  [tex]H_a : \mu > 17[/tex]

Generally the degree of freedom is mathematically represented as  

         [tex]df = n -1[/tex]

=>       [tex]df = 25 -1[/tex]

=>       [tex]df = 24[/tex]

Generally the test statistics is mathematically represented as

        [tex]t = \frac{\= x- \mu }{\frac{s}{\sqrt{n} } }[/tex]

=>   [tex]t = \frac{ 17 - 15 }{\frac{5.5}{\sqrt{25} } }[/tex]

=>   [tex]t = 1.8182[/tex]

Generally from the student t distribution table the probability of obtaining   [tex]t = 1.8182[/tex] to the right of the curve at a degree of freedom of [tex]df = 24[/tex]  is  

    [tex]p-value = P(t > 0.18182 ) = 0.4286[/tex]

From the value obtained we see that  [tex]p-value > \alpha[/tex] hence

The decision rule is  

Fail to reject the null hypothesis

 The conclusion is  

There is no sufficient evidence to show that  the  designer's claim of a better shoe is  supported by the trial results.

Answer:

There are two, the first one is 4 and the second is 132

Step-by-step explanation:

36 divided by 3 is 12, so 48 divided by 12 would give us the answer 4. In the last one, you multiply 11 by 12 instead.

Step-by-step explanation:

the second one is 132 uuwwuu

Answer:

y=0

Step-by-step explanation:

Answer: Yes

Step-by-step explanation: We're going to have to substitute

in the coordinates of that ordered pair into the equation.

I am going to substitute in the x and substitute in the y.

So it's really 5(2) + 3(-3) = 1.

From here it should be pretty straightforward,

all we are doing is evaluating the statement.

Simplifying on the left we have 10 + -9 = 1 or 1 = 1.

Now we know that the ordered pair (2, -3) satisfies this equation.

Answer:

[tex]\frac{1}{16}[/tex]

Step-by-step explanation:

[tex]6\frac{1}{4}=\frac{25}{4}[/tex]

since percent means divided by 100

[tex]\frac{25}{4} *\frac{1}{100}[/tex]

=[tex]\frac{1}{16}[/tex]

66-95-99.7 rule

standard deviation is 10. meaning that it'll deviate twice meaning you use the 95%

95% of 200 is 190, so 190 students had scores between 40 and 80

Answer:

Coordinates of point C after dilation with a scale factor of 5, centered at the origin will be: C'(10, 5)

Step-by-step explanation:

Given the point C

A dilation with a scale factor of 5 means the size of the coordinates of the image of point P will be 5 times larger than than the original coordinates of point C.

Thus, the rule of dilation by a scale factor 5 is:

(x, y)  →  (5x, 5y)

C(2, 1)  →  (5x, 5y) = (5(2), 5(1)) = C'(10, 5)

Therefore, coordinates of the point C after dilation with a scale factor of 5, centered at the origin will be: C'(10, 5)

Answer:

288

Step-by-step explanation:

Evaluate Using the Given Value

2 (a (2b + 3c)) for a = 8 , b = 3 , and c = 4

Replace the variable a with 8 in the e xpression.

2 ((8) (2b + 3c))

Replace the variable b with 3 in the expression.

2 ((8) (2 (3) + 3c))

Replace the variable c with 4 in the expression.

2 ((8) (2 (3) + 3 (4)))

Simplify each term.

Multiply 2 by 3.

2 (8 (6 + 3 (4)))

 Multiply 3 by 4.

2 (8 (6 + 12))

Simplify the expression. Tap for fewer steps...

Add 6 and 12.

2 (8 ⋅ 18)

 Multiply 8 by 18.

2 ⋅ 144

 Multiply 2 by 144.

True Triangles are 3 sided polygon's

Answer:

Linear function: y = 24x + 25

Step-by-step explanation:

24 hours = 1 day

30 days = 1 month

0.15 x 24 = 6

30 x 6 = 180

180 + 25 = 205

Linear function: y = 24x + 25
