A bag contains 4 red marbles, 3 blue marbles and 6 green marbles. If two marbles are
drawn out of the bag, what is the probability, to the nearest 1000th, that both
marbles drawn will be red?

Answers

Answer 1

Answer:

~0.143

Step-by-step explanation:

So, in total there are 15 marbles, and only 6 of them are red. So the first draw will have a  chance of being red. Since you didn't mention placing it back, the next draw will have a  chance of being red. It's  , because you just took a red one out of the bag (leaving 5 left) and the total was lessened by one. To get the answer, you'd multiply both numbers together.

6/15 x 5/14 = 1/7 or (roughly) 0.143

The circumference of a circle is 10.4mm.
Find the length of the diameter.
Give your answer rounded to 3 SF.

Answers

Answer:

diameter: 3.31 mm

Explanation:

circumference of circle → πd

using the formula:

10.4 = πd

d = 10.4/π

d = 3.31 mm

Answer:

diameter = 3.31 mm (3 sf)

Step-by-step explanation:

Diameter of a circle (d) = 2r  (where r is the radius)Circumference of a circle = 2[tex]\pi[/tex]r  (where r is the radius)
⇒ circumference = [tex]\pi[/tex]d

Given:

circumference = 10.4 mm

⇒ [tex]\pi[/tex]d = 10.4

⇒ d = 10.4 ÷ [tex]\pi[/tex] = 3.31 mm (3 sf)

A scuba diver is 30 feet below the surface of the water 10 seconds after he entered the water and 120 feet below the surface after 40 seconds. What is the scuba diver's rate of change (include the units)?
Find slope(Rate of Change)

Answers

Answer:

3 feet  per second

Step-by-step explanation:

The rate of change is:

m = the change in depth / the change in time =      (120 - 30) / (40 - 10) =      90 / 30 =      3 feet/second

Take 2 points

(10,30)(40,120)

Rate of change=Slope:-

[tex]\\ \rm\hookrightarrow m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \rm\hookrightarrow m=\dfrac{120-30}{40-10}[/tex]

[tex]\\ \rm\hookrightarrow m=\dfrac{90}{30}[/tex]

A family goes to a theme park. The two grandparents pay 1/3
of the full entrance price. The two parents pay full price and the three children pay half price. A full price tickst costs £5.70. How much was the total cost of admission for the family?​

Answers

grandparents ticket each: £1.90 x 2 = £3.80
parents ticket each: £5.70 x 2 = £11.40
children ticket each: £2.85 x 3 = £8.55
total: £23.75
1/3 x 5.70 = £1.90 (what a grandparent payed)

£1.90 x 2 = £3.80 (the cost for both grandparents)

5.70/2 = £2.85 (what one child payed)

2.85 x 3 = £8.55 (the cost for all three children)

5.70 x 2 = £11.40 (the cost for both parents)

Add them all up

3.80 + 8.55 + 11.40

= £23.75 for the whole family

Answers

Answer:

f(x) is a parabola with a vertex at (0, 0) that opens up

g(x) is a parabola with a vertex at (0, 2) that opens up

Step-by-step explanation:

Quadratic equation:  [tex]y = ax^2 + bx + c[/tex]

The graph of a quadratic equation is a parabola.  The value of [tex]a[/tex]determines its orientation.

If [tex]a>0[/tex] then the parabola opens upwards and its vertex is its minimum point.  

If [tex]a<0[/tex] then the parabola opens downwards and its vertex is its maximum point.

Given:

f(x) = x²g(x) = x² + 2

⇒ g(x) = f(x) + 2

So the transformation of f(x) to g(x) is an upward shift of 2 units, or

a translation of f(x) by the vector [tex]\left(\begin{array}{ccc}0\\2\end{array}\right)[/tex].

Therefore, the y-coordinate of the vertex of g(x) will be 2 units more than the y-coordinate of the vertex of f(x).

Therefore,

f(x) is a parabola that opens upwards with a vertex at (0, 0)g(x) s a parabola that opens upwards with a vertex at (0, 2)

Abigail and her mom want to make matching pairs of polka-dotted pajama pants. So, they go to the craft store to pick out fabric. Abigail needs 4 feet of fabric for her pajamas, and her mom needs 6 feet of fabric. But, the store only sells fabric by the yard. If they buy 4 yards of fabric, how many feet will be leftover?

Answers

Answer: 2 feet

Explanation: A yard is 3 feet.
4 feet for Abigail and 6 for her mother makes 10 feet in total.
4 yards x 3 (to convert to feet, every yard is 3 feet, so you multiply) equals 12 feet.
12 - 10 is 2.

How to find the median of 30 37 8

Answers

Answer:

to find the median, divide the odd number by 2 and round it up

for even numbers, only divide by 2.

Average the numbers with the number in the next highest position.

You have a median.

In this case, the median is 30.

The median of the numbers 30, 37, and 8 is 30.

To find the median of a set of numbers, you first need to arrange the numbers in either ascending or descending order and then determine the middle value.

Given the numbers: 30, 37, 8

Arrange the numbers in ascending order:

8, 30, 37

Determine the middle value:

Since there are three numbers, the middle value is the second number, which is 30.
