Odd couple. If n is an odd number greater than or equal to 3, can n+1 ever be prime? What if n equals 1?

Answer:

parabola

Step-by-step explanation:

The path followed by a ball can be modeled by a graph.

Throwing a ball is a parabola or quadratic graph.

When a ball is thrown, the path it follows can be represented by:

[tex]\mathbf{f(x) = ax^2 + bx + c}[/tex]

or

[tex]\mathbf{f(x) = a(x - h)^2 + k}[/tex]

The above equations are functions of a parabola or quadratic graph.

Hence, throwing a ball is a parabola or quadratic graph.

Answer:

Tan 50 = H/24

Step-by-step explanation:

The set up will give a right angled triangle;

Given the following

angle of elevation = 50degrees

Distance of elevation from the flagpole base = 24m (Adjacent)

Required

Height of the flagpole (Opposite) = H

Using the SOH CAH TOA identity

Tan theta = opposite/adjacent

Tan 50 = H/24

H = 24tan50

H = 24(1.1918)

H = 28.60

Hence the required expression is Tan 50 = H/24 where H is the height of the flagpole

The height of the flagpole is 28.60.

Given

The angle of elevation to the top of a flagpole is 50 degrees.

The angle of elevation was measured 24 from the base of the flagpole.

The angle of elevation of the sun is the angle formed between the horizontal line and your line of sight when you look at the sun.

Let the height of the flagpole be H.

Then,

The height of the flagpole is given by;

[tex]\rm Tan\theta=\dfrac{Opposite \ side}{Adjacent \ side}\\\\[/tex]

Substitute all the values in the formula;

[tex]\rm Tan\theta=\dfrac{Opposite \ side}{Adjacent \ side}\\\\ \rm Tan50=\dfrac{H}{24}\\\\H = 24 \times tan50\\\\H = 24\times 1.91\\\\H=28.60[/tex]

Hence, the height of the flagpole is 28.60.

Anne Hathaway 2:11

So [tex]p = \frac{2}{2+11} = \frac{2}{13} = 0.154[/tex]

Angelina Jolie 1:20

So [tex]p = \frac{1}{1+20} = \frac{1}{21} = 0.048[/tex]

Melissa Leo 1:33

So [tex]p = \frac{1}{1+33} = \frac{1}{34} = 0.029[/tex]

Meryl Streep 3:10

So [tex]p = \frac{3}{3+10} = \frac{3}{13} = 0.231[/tex]

Answer:

Step-by-step explanation:

28 cows × 6 days = 168 cow-days

(168 cow-days)/(21 cows) = 8 days

If a field of grass feeds 28 cows for 6 days, the number of days that the same field would feed 21 cows is 8 days.

This question involves the use of inverse proportion to solve.

According to this question, a field of grass feeds 28 cows for 6 days. The number of days it would take 21 cows is calculated as follows:

28 cows is fed for 6 days

21 cows will be fed for (28 × 6) ÷ 21 = 8 days.

Therefore, If a field of grass feeds 28 cows for 6 days, the number of days that the same field would feed 21 cows is 8 days.

The number of hours he spent babysitting is 12 hours and the number of hours he spent mowing lawns last week is 8 hours.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Given that, John works two jobs. He earns $10 an hour babysitting his neighbour's children and $15 an hour mowing lawns in his neighbourhood. Last week he worked a total of 20 hours and earned a total of $240.

Let the x be the number of hours he spent babysitting and y be the number of hours he spent mowing lawns last week,

Establishing the equation, we get,

x+y = 20

x = 20-y......(i)

10x+15y = 240.......(ii)

Using the equation (i) in (ii), we get

10(20-y)+15y = 240

200-10y+15y = 240

5y = 40

y = 8

Put y = 8 in eq(i)

x = 20-8

x = 12

Hence, the number of hours he spent babysitting is 12 hours and the number of hours he spent mowing lawns last week is 8 hours.

P(E) = 0.5

P(A) = 0.2

P(N) = 0.3

Conditional probability ;

0.47

Step-by-step explanation:

Let :

E = Excellent ; A = Average ; N = not up to standard

P(E) = 0.5

P(A) = 0.2

P(N) = 0.3

If Leo shows up ; this type of probability is called a conditional probability. It is the likelihood of an event based on a certain or already satisfied condition.

The probability that Leo is coming :

Leo ; Excellent = 0.7

Leo ; Average = 0.3

Leo; Not up to standard = 0.2

Hence, probability they Leo is coming :

(0.5 * 0.7) + (0.2 * 0.3) + (0.3 * 0.2)

0.35 + 0.06 + 0.06
