The probability that the number spun is a 3 given that it was less than 4 is 1/6.

Let A is the event of a number less than 4.

P(A) is the probability of getting a number less than 4.

The total number less than 4 is 3

Here, the total numbers in the game are 6.

By the Formula for the probability of an event E can be observed as:

P(A)= no of favorable cases/total no. of cases  = 3/6 = 1/2

B is the event of getting the number  3

P(B) be the probability of getting 3

The total  possible cases  is 1

Therefore , P(B)= 1/6

Now, P(B/A) is the probability of getting 3 which is an odd number.

P(B/A)= P(A ∩ B) / P(A)

          =1/6 / 1/2

   = 1/3

We get the absolute value inequality as | x - 88 | > 38.

We are given that:

Hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) are potentially dangerous and can occur when a person's blood sugar fluctuates by more than 38 mg from the normal blood sugar level of 88mg. We need to write an inequality for it.

We know that the blood sugar level should not be less than:

88 mg - 38 mg = 50 mg

Also, the blood sugar level should not be higher than:

88 mg + 38 mg = 126 mg

The inequality then will become:

50 mg ≤ Blood sugar level ≤ 126 mg.

The absolute value inequality will be:

| x - 88 | > 38

Therefore, we get the absolute value inequality as | x - 88 | > 38.

Answer:

Pencils = 35

Notebooks = 15

Step-by-step explanation:

15 cents = 15/100 = $0.15

85 cents = 85/100 = $0.85

p + n = 50                    Eq. 1

0.15p + 0.85n = 18       Eq. 2

p = number of pencils

n = number of notebooks

From Eq. 1

p = 50 - n               Eq. 3

Replacing Eq. 3 in Eq. 2:

0.15(50-n) + 0.85n = 18

(0.15*50 + 0.15*-n) + 0.85n = 18

(7.5 - 0.15n) + 0.85n = 18

7.5 + 0.7n = 18

0.7n = 18 - 7.5

0.7n = 10.5

n = 10.5 / 0.7

n = 15

From Eq. 3:

p = 50 - n

p = 50 - 15

p = 35

Check:

From Eq. 2

0.15p + 0.85n = 18

0.15*35 + 0.85*15 = 18

5.25 + 12.75 = 18

The given pattern 5/7, 8/7, 11/7, 2, ....... is in the form of the arithmetic progression AP. The next 3 terms are  17/7, 20/7, 23/7.

An arithmetic progression is a sequence whose terms continue to increase and otherwise decrease by a constant number. The common difference is the set amount through which they either increase or decrease.

The following arithmetic progression formulas are frequently utilized to solve various AP problems for the initial term 'a' of an AP and the common difference 'd'-

Now, as per the stated question;

The AP given as; 5/7, 8/7, 11/7, 2, ...........

The series consists of four given terms.

Consider the initial term be 'a₁' = 5/7.

Then, the second term be 'a₂' = 8/7.

And, the third term be 'a₃' = 11/7.

And, the fourth term is 'a₄' = 2.

The AP have the same common difference. so,

d = a₃ - a₂

Substitute the values.

d = 11/7 - 8/7

d = 3/7

Thus, the common difference is 3/7.

or d = a₄ - a₃ (Put the values)

d = 2 - 11/7

d = 3/7

As, a₃ - a₂ = a₄ - a₃

Thus, we can conclude that the given sequence is in AP.

The fifth term will be; a₅ = a₄ + d = 2 + 3/7

a₅ = 17/7

Now, the 6th term will be; a₆ = a₅ + d = 17/7 + 3/7

a₆ = 20/7

Similarly, the 7th term will be; a₇ = a₆ + d = 20/7 + 3/7

a₇ = 23/7

Therefore, it can be said that the given sequence is in AP next three terms be 17/7, 20/7, 23/7.

The length of the unknown leg is 8 yd in the given right triangle.

The Pythagoras theorem states that a right-angled triangle's hypotenuse square (90 degrees) equals the sum of the squares of its other two sides.

Let the three legs of the right triangle be a, b and c where a is the altitude, b is the base and c is hypotenuse of the given right angled triangle.

Here, a = [tex]\sqrt{23}[/tex] yd, b = ? and c = [tex]\sqrt{87}[/tex]

According to the Pythagoras theorem,

Hypotenuse² = Base² + Altitude²

c² = b² + a²

[tex](\sqrt{87})^{2}[/tex] = b² + [tex](\sqrt{23})^{2}[/tex]

87 = b² + 23

Subtracting 23 from both sides of the equation.

87 - 23 = b²

b² = 64

Taking square root of the both sides.

b = ± 8

Since the value of length can't be negative so the value of b = - 8 is rejected.

Therefore, the value of b = 8 yd.

As we have calculated above, the length of the unknown leg is 8 yd.

Hope this helps!

Answer:

r=2

Step-by-step explanation:

To find the slope, we take the difference in the y values over the difference in the x values

m = ( y2-y1)/(x2-x1)

2 = ( 9-3)/ (5-r)

2 = (6)/(5-r)

Multiply each side by (5-r)

2 ( 5-r) = 6

Divide each side by 2

5-r = 6/2

5-r = 3

Subtract 5 from each side

5-r-5 = 3-5

-r = -2

r = 2

Answer:

r = 2

Step-by-step explanation:

To solve this problem, we have to use the following formula for slope:

[tex]\boxed{m= \frac{y_2 - y_1}{x_2 - x_1}}[/tex],

where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are the coordinates of two points.

We are given the coordinates [tex](r, 3)[/tex] and [tex](5, 9)[/tex], and told that [tex]m = 2[/tex]. To find the value of r, we have to substitute the given values into the formula and then solve for r :

[tex]2 = \frac{9 - 3}{5-r}[/tex]

⇒ [tex]2 = \frac{6}{5-r}[/tex]

⇒ [tex]2\times (5-r) = \frac{6}{5-r} \times (5 - r)[/tex]         [Multiplying both sides by (5 - r)

⇒ [tex]2(5-r) = 6[/tex]

⇒ [tex]\frac{2}{2}(5-r) = \frac{6}{2}[/tex]                                [Dividing both sides by 2]

⇒ [tex]5- r = 3[/tex]

⇒ [tex]5 - r - 5 = 3 - 5[/tex]                         [Subtracting 5 from both sides]

⇒ [tex]-r = -2[/tex]

⇒ [tex]\frac{-r}{-1}= \frac{-2}{-1}[/tex]                                       [Dividing both sides by -1]

⇒ [tex]r = \bf 2[/tex]

⇒ 2-2=36a-6b+2-2
