Answer:

5/36 is your answer.

Step-by-step explanation:

If the red die shows a "2", then the blue die must take on the values from the set {2,3, 4, 5, 6} in order for the sum of both dice to be larger than 4.

1+2=3

2+3 = 5

2+4 = 6

2+5 = 7

2+6 = 8

There are 6*6 = 36 total ways to roll two dice and exactly 5 ways to get the conditions stated above. The probability of getting a sum greater than 2 is 5/36

The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences. Then the probability is given as,

P = (Favorable event) / (Total event)

Cindy throws one red and one blue regular (six-sided) fair dice. The total number of events will be

Total events = 6 x 6 = 36

The probability that the sum of the two dice is greater than 2 will be given as

P = 1 - 1 / 36

P = 35 / 36

The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.

Write an addition expression for the temperature relative to when Iko woke up.

Answer:

[tex]T = x -3[/tex]

Step-by-step explanation:

Let the temperature when he woke up be x

When he woke up, it rises to 11 degrees.

This is represented as:

[tex]t_1 = 11[/tex]

At bedtime, it dropped by 14 degrees.

This gives

[tex]\triangle t = 11 - 14[/tex]

[tex]\triangle t = -3[/tex]

Answer:

x = 9

Step-by-step explanation:

Opposite sides of a parallelogram are equal.

16x - 15 = 11x + 30          Subtract 11x from both sides

16x - 11x - 15 = 30           Combine the left

5x - 15 = 30                    Add 15 to both sides

5x = 30 + 15                   Combine the right

5x = 45                           Divide by 5

5x/5 = 45/5

Given that 0 find the value of a and the value of b.

(2 marks)

.

The values of a and b are π/2 and -1, respectively

The parent function of a sine function is:

y = sin(x)

When the function is shifted left by π/2 units, it becomes

y = sin(x + π/2)

When the function is shifted down by 1 unit, it becomes

y = sin(x + π/2) - 1

This means that the graph of y = sin(x + π/2) - 1 is the sine graph shifted left and down by π/2 and 1 unit respectively.

By comparing y = sin(x + π/2)° - 1 and y = sin(x + a)° + b, we have:

a = π/2 and b = -1

Hence, the values of a and b are π/2 and -1, respectively

I graphed and got the answer.

Answer:

y < 50x

Step-by-step explanation:

In order to graph this inequality, you first need to identify the important word(s) here to find the inequality sign; in this case, it would be "maximum of $50" a month. Since it's a maximum of $50 a month (or less than $50 a month), you can write it as:

Where m is months and c is total cost, c < 50m

If you need to graph this, you can write it as y < 50x. The cost is y since it's the output, and months is x since that's the input.

Option A is the correct answer.

A set is a collection of items where there are operations such as:

Union of sets, the intersection of sets, and the complement of sets.

We have,

Let event A = The place is a city.

Let event B = The place is in North

Now,

A = { Tokyo, Houston New york, Tijuana

B = { Houston, New York, Tijuana, Canada }

The outcomes in A or B.

A or B

The polynomial 3x²+12x+14 cannot be factored by factoring out a GCF. Therefore, option D is the correct answer.

The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.

Here,

a) 9x²-81x+27

In the given trinomial, in each term 9 is the common factor, so, the GCF of the trinomial is 9.

Thus, 9(x²-9x+3)

b) 15x²+3x

The factors of each terms of binomial is listed below

15x²=3×5×x×x

3x=3×x

So, the GCF is 3x

Now, 3x(5x+1)

c) 2x+4

The factors of each terms of binomial is listed below

2x=2×x

4=2×2

So, the GCF is 2

Now, 2(x+2)

d) 3x²+12x+14

In this trinomial there is no common term.

Therefore, option D is the correct answer.

Answer: 5 hours  

Step-by-step explanation:

Ishwar's speed per hour:

Number of 15 minute periods in an hour:

= 4 periods

Ishwar reads at 5 pages in 15 minutes so in an hour Ishwar would read:

= 4 * 5

= 20 pages per hour

Annie = 15 pages in an hour.

Ishwar number of hours to read 300 pages:

= 15 hours

Annie number of hours to read 300 pages:

= 300 / 15

= 20 hours

Answer:

The amount Lilian needs to invest is $5,160

Step-by-step explanation:

The parameters of the amount Lilian is going to invest in an account are;

The interest rate the account pays = 5.7%

The final amount the investment is expected to reach after the given time period = $7,600

The number of years of the investment = 7 years

The formula for compound interest is presented as follows;

[tex]A = P \cdot \left(1 + \dfrac{r}{n} \right)^{n\cdot t}[/tex]

Where;

A = The final amount = $7,600

P = The amount Lilian is to invest

r = The interest rate = 5.7% = 0.057

n = The number of times the interest is applied per time period = 1

t = The number of period that passes = 7 (years)

Therefore, we get;

[tex]7,600 = P \cdot \left(1 + 0.057 \right)^{7}[/tex]

∴ P = 7,600/(1 + 0.057)⁷ = 5,155.7123754

The amount Lilian needs to invest (rounded to the nearest ten dollars) for the value of the account to reach $7,600 in 7 years, P = $5,160
