Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

"The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible".

Here the number of favorable outcomes is 4, and the number of total outcomes is 6.

So the probability of NOT rolling a 1 or 6 is [tex]\frac{4}{6}[/tex] which is [tex]\frac{2}{3}[/tex]

Answer

D. -18

Step-by-step explanation:

p ( x ) = 5x + 30, q ( x ) = 11x -24

( q - p ) (6 ) = 11x -24 - ( 5x + 30 )

                  = 11.6 - 24 - 5.6 - 30

                  = 66 - 24 - 30 -30

                  = 42 -30 -30

                  = 12 -30

                  = -18

Answer:

4. Translation 6 unit right and 2 units down.

Step-by-step explanation:

Let' take the point and it's corresponding image.

x(-2,0) and x'(4,-2)

Now,let's find the translation

-2+? =4

0+? =-2

Now, if we solve each for ?, we get

-2+?=4, gives ? =6

0+?=-2 gives ?=-2

It means the translation is move right 6 units and down 2 units.

So, option 4 is right.

Answer:

so involved triangles we know that one angle is 90° because of the right angle sign and you know that two x two interior angles add up to 180 angle so 90 degrees we will name the unknown angle x + x is equals to 127 degrees x is equals to 37 degrees so we have two angles are both of the triangles that is 90 degrees and 37 degrees 37 degrees is on the upper part of the triangle so it'll be 37° + 37° to get 74 degrees and the angle that you're looking for is a reflex angle so it'll be 360 degrees - 74 degrees so they think the answer is 286 degrees

Answer:

n>4

Step-by-step explanation:

1. Let's first simplify each sides.

7 + 13n − 1 > 5(2n+2) + 8

a. 7 - 1

Distribute the 5.

b. 5 x 2n = 10n

   5 x 2 = 10

c. 10n + 10 + 8 = 10n + 18

13n + 6 > 10n + 18

2. Now, eliminate 10n on both sides, as there can't be 2 variables on the opposite sides.

13n  + 6 > 10n + 18

-10n        -10n

a. 3n + 6 > 18

3. Subtract 6 from each side.

3n + 6 > 18

     -6     -6

a. 3n > 18

Divide 3

b. n > 4

Step-by-step explanation:

combine the like terms

7x^2 + 12x + 7

The 90% confidence interval for the population mean is (132.1, 143.9). Then the correct option is C.

The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.

A simple random sample of 90 is drawn from a normally distributed population, and the mean is found to be 138, with a standard deviation of 34.

The 90% confidence interval for the population mean. Then we have

[tex]\rm Margin \ of \ error = z * \dfrac{Standard \ deviation}{\sqrt{sample \ size}}\\\\\\\Margin \ of \ error = 1.645 * \dfrac{34}{\sqrt{90}}\\\\\\Margin \ of \ error = 5.9[/tex]

The interval will be given as

Mean ± Margin of error

138 ± 5.9

Then the interval will be (132.1, 143.9).

Answer:

-5x² + 2x + 3

Step-by-step explanation:

Since its a trinomial, it has three terms.

Since it has a degree 2, the highest degree is 2 and will usually be the first term.

The coefficient of the first term must have a -5.

Standard form is like  ax² + bx + c

Where a,b, and c are variables.

So,  -5x² + 2x + 3 should work

We know the standard form

Answer: 4,9,14,19,24

The term to term rule is "add 5"

Step-by-step explanation:

From the question,

First term = a = 4

Fifth term = a+(n-1)d = a+(5-1)d = a+4d = 24

Since a + 4d = 24

We slot on the value of a

a + 4d = 24

4 + 4d = 24

4d = 24 - 4

4d = 20

d = 20/4

d = 5

The term to term rule will be "add 5"

The arithmetic sequence will be:

4

4+5 = 9

9+5 = 14

14+5 = 19

19+5 = 24

Answer:

Given that,

x⁴y⁵ + x⁵y⁴ = 810

➝ x⁴y⁴(x+y) = 810 ---(1)

[tex] \: [/tex]

Further given that,

x⁶y³ + x³y⁶ = 945

x³y³(x³y³) = 945

[tex] \: [/tex]

We know,

[tex] { \boxed{{x}^{3} + {y}^{3} = (x + y)( {x}^{2} - xy + {y}^{2}) }}[/tex]

So, using this identity, we get,

---(2)

[tex] \: [/tex]

On dividing equation (1) and (2), we get,

To see which amount of tickets is the best deal, look at the unit price of each.

To do this, divide the cost of the tickets by the number of tickets to see how much money a single ticket costs in each of the deals.

A) Buying 25 tickets for $10.00 offers the best deal because each ticket is only worth $.40, compared to the other deals where each ticket is worth $.50 or $.42.

B) Usually, businesses offer a better discount the more of a good someone buys due to marketing purposes. I would suggest that the students make the discount higher as the number of tickets increases. Therefore, more people would be willing to buy more tickets and both the consumer and seller will be happy because more discounts (consumer = happy) and more profit (more ticket sales -> business = happy).

Answer:

General form of an exponential function:  [tex]y=ab^x[/tex]

where:

If [tex]b > 1[/tex]  then it is an increasing function

If [tex]0 < b < 1[/tex] then it is a decreasing function

Also [tex]b\neq 1[/tex]

Given:

[tex]\implies y=(-3)b^x[/tex]

If we want the function to be decreasing, then as [tex]a[/tex] is negative, we need [tex]b > 1[/tex] to make the overall function decreasing.  

Let [tex]b=2[/tex] :

[tex]\implies y=(-3)2^x[/tex]

If we want the function to be increasing, then as [tex]a[/tex] is negative, we need [tex]0 < b < 1[/tex] to make the overall function increasing.

Let [tex]b=\dfrac12[/tex] :

[tex]\implies y=-3\left(\dfrac12\right)^x[/tex]

However, it doesn't matter whether the function is increasing or decreasing as the range of both of the above given functions is < 0 as [tex]a[/tex] is negative and [tex]b[/tex] is positive.
