Answer:

With Remainder: 2 R2

Step-by-step explanation:

Multiply 3 and 6

= 18

Divide 18 and 8 = 2 R2

If you need it without the remainder, put it in the comments and I'll give it without the remainder.

➷ First, according to PEMDAS, you need to do multiplication and division from left to right.

3*6=18

Then, you divide that by 8:

18/8=2.25

Final answer:

2.25

Let X be a binomial random variable with p = 0.7 and n = 10. Calculate the following probabilities from the binomial probability

padilas [110]

Answer:

0.4114

0.0006

0.1091

0.1957

Step-by-step explanation:

Given:

p = 0.7 n = 10

We need to determine the probabilities using table , which contains the CUMULATIVE probabilities P(X $\leq$ x).

a. The probability is given in the row with n = 10 (subsection x = 3) and in the column with p = 0.7 of table:

P(X $\leq$ 3) = 0.4114

b. Complement rule:

P( not A) = 1 - P(A)

Determine the probability given in the row with n = 10 (subsection x = 10) and in the column with p = 0.7 of table:

P(X $\leq$ 10) = 0.9994

Use the complement rule to determine the probability:

P(X > 10) = 1 - P(X $\leq$ 10) = 1 - 0.9994 = 0.0006

c. Determine the probability given in the row with n = 10 (subsection x = 5 and x = 6) and in the column with p = 0.7 of table:

P(X $\leq$ 5) = 0.8042

P(X $\leq$ 6) = 0.9133

The probability at X = 6 is then the difference of the cumulative probabilities:

P(X = 6) = P(X $\leq$ 6) - P(X $\leq$ 5) = 0.9133 — 0.8042 = 0.1091

d. Determine the probability given in the row with n = 10 (subsection x = 5 and x = 11) and in the column with p = 0.7 of table:

P(X $\leq$ 5) = 0.8042

P(X $\leq$ 11) = 0.9999

The probability at 6 $\leq$ X $\leq$ 11 is then the difference between the corresponding cumulative probabilities:

P(6 $\leq$ X $\leq$ 11) = P(X $\leq$ 11) - P(X $\leq$ 5) = 0.9999 — 0.8042 = 0.1957

Step-by-step explanation:

Here you go mate

Use PEMDAS

Parenthesis,Exponent,Multiplication,Division,Addition,Subtraction

Step 1

4(x+9)=76 Equation/Question

Step 2

4(x+9)=76 Remove parenthesis by multiplying 4

4x+36=76

Step 3

4x+36=76 Subtract 36 from sides

4x=40

Step 4

4x=40 Divide sides by 4

Keisha swims 18 ft from one side of her circular pool to the other, swimming straight through the center. She then swims one tim

elena-s [515]

Answer:

Swimming one time around the pool is 56.5 ft

Step-by-step explanation:

Swimming 18 ft from one side of her circular pool to the other, swimming straight through the center means the circular swimming pool has a diameter of d=18 ft.

The circumference of the circle is calculated using:

$c = \pi \: d$

where d=18 is the diameter and π=3.14 as given.

We substitute the values to get:

$c = 3.14 \times 18$

$c = 56.52$

We approximate to the nearest tenth to get:

$c = 56.5ft$

madreJ [45]

Answer:

$x = 3 + 4\sqrt{3}$

Step-by-step explanation:

OPQ is a right angle triangle.

Using Pythagoras

$x^{2} + (x+5)^{2} = (x+8)^{2}\\x^{2} + x^{2} + 10x +25 = x^{2} + 16x + 64\\x^{2} + x^{2} - x^{2} + 10x - 16x + 25 - 64 = 0\\x^{2} - 6x -39 = 0$

Using quadratic formula

$x = \frac{-b \± \sqrt{b^{2}-4ac}}{2a}\\x = \frac{-(-6) \± \sqrt{(-6)^{2}-4(1)(-39)}}{2(1)}\\x = \frac{6}{2} \± \frac{\sqrt{192}}{2}\\x = 3 \± \frac{8\sqrt{3}}{2}\\x = 3 \± 4\sqrt{3}$

$x = 3 + 4\sqrt{3} = 9.928(4s.f.)$

$x = 3 - 4\sqrt{3} = -3.928(4s.f.)$ (Length can't be negative)

∴ $x = 3 + 4\sqrt{3}$
