Mathematics
1 answer:
alexandr402 [8]3 years ago
6 0

Answer:

$25.00

Step-by-step explanation:

You already know that $85 is an additional fee added to the monthly fees.

So, you first have to subtract 85 from $685 to get the total amount of monthly fees paid over 2 years.

685-85= 600

So, you can conclude that $600 is the total amount of monthly fees paid.

Now, you want to divide 600 by (the number of months in 2 years) to get the amount of monthly fees.

Since there is 24 months in 2 years you do:

600/ 24 which equals 25.

In conclusion, you can find that the monthly fee is $25.00.

Classify each pair of numbered angles. Drag and drop the descriptions into the boxes to correctly classify each pair of numbered
Leona [35]

(i) Pairs of <em>neighboring</em> angles are <em>supplementary</em> and <em>opposite</em> angles have the <em>same</em> measure.

(ii) The two angles formed by a line coming out of another line are <em>supplementary</em>.

<h3>How to analyze pairs of angles</h3>

(i) When two <em>straight</em> lines pass through each other, then <em>two</em> pairs of <em>opposite</em> angles are constructed. A pair with angles of (3\cdot x + 52)^{\circ} and another pair with angles of (2\cdot x + 2)^{\circ}, each pair of angles with <em>different </em>measures are <em>supplementary</em>.\blacksquare

(ii) When a <em>straight</em> line comes out of another <em>straight</em> line, from a point distinct to any endpoint of the former, then we construct two <em>supplementary</em> angles. The <em>largest</em> angle has a value of (10\cdot x + 20)^{\circ}, whereas the <em>smaller</em> one has a value of (6\cdot x + 8)^{\circ}. \blacksquare

Tamara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible c
lutik1710 [3]

Answer:

Tamara should expect the sum of the two cubes to be equal to 5 20 times.

Step-by-step explanation:

The sample space of rolling a number cube are:

S = {1, 2, 3, 4, 5, 6}

If two such cubes are rolled together, then the sum of the two cubes will be 5 for the combinations below:

S₁ = {(1, 4), (2, 3), (3, 2) and (4, 1)}

The total number of outcomes will be, <em>N</em> = 36.

Compute the probability that the sum of rolling two numbered cubes as follows:

P(\text{Sum}=5)=\frac{4}{36}=\frac{1}{9}

Let <em>X</em> = number of time the sum of the two numbers on two cubes is 5.

Two numbered cubes are rolled <em>n</em> = 180 times.

The event of getting a sum of 5 in independent of the other results.

The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> = 180 and <em>p</em> = \frac{1}{9}.

The expected value of <em>X</em> is:

E(X)=np

Compute the expected number of times Tamara expects the sum of the two cubes to be equal to 5 as follow:

E(X)=np\\=180\times \frac{1}{9}\\=20

Thus, Tamara should expect the sum of the two cubes to be equal to 5 20 times.
