Probability would be that you randomly select 5 cards so the selection goes above the fraction and the total amout of cards goes below.
Answer:
3243 / 10829 ≈ 0.2995
Step-by-step explanation:
There are 52 cards in a deck. 5 cards are selected, so the number of possible combinations is ₅₂C₅.
Of the 5 cards selected, 1 is a Jack and 4 are non-Jacks.
There are 4 Jacks in a deck. The number of ways of choosing 1 Jack from 4 is ₄C₁.
There are 48 non-Jacks in a deck. The number of ways of choosing 4 non-Jacks from 48 is ₄₈C₄.
So the probability is:
P = ₄C₁ ₄₈C₄ / ₅₂C₅
P = 4 × 194580 / 2598960
P = 778320 / 2598960
P = 3243 / 10829
P ≈ 0.2995

Consider the following ratios and state that whether these ratios forms a proportion?
Case1 - 20 friends to 15 strangers
Case 2 - 4 friends to 3 strangers
A.Yes
B.No
Part B
Find the ratio of the number of friends in Case 1 to the number of friends in Case 2.
Answer: ____________
Note: Type the answer as shown. Ex: (3:8)
Answer:
Prt A- Yes
Part B- 5:1
Step-by-step explanation:
The ratios in cases 1 and 2 form a proportion. This can be seen by dividing case a by 5 which gives 4:3;
i.e 20:15 = 20
15
If you divide both numerator and denominator by 5, we have 4/3.
This shows that case 1 and 2 have the same proportions of friends to strangers.
Part B.
The number of friends in case 1 is 20 while in case 2 is 4.
we have, 20:4
= 20
4
Dividing each by 4, we have 5:1.
This means that the ratio of friends that in case 1 to case 2 is 5:1.

Ivy randomly surveys students in her school to learn about mobile phone password use. Of 25 respondents, 14 use a password. Based on Ivy’s data, how many of the 275 students in her school would be expected to use a password?
Answer:154
Step-by-step explanation:
14/ 25 = x/275
multiply 14* 275 then divide by 25 to get 154
Answer:
168
Step-by-step explanation:
If 14/25 have passwords, and there are 275 students in her school, then the equation should be 275/25=12, 12*14=168

Am new to this chapter and I don't understand it too well.
Please help me
Answer:
x is 60°
y is 30°
(would really, reallly appreciate the brainliest)
Step-by-step explanation:
x can be seen as what's needed to do a full 180 ° turn when you already turned 120°
y is 60° bc the sum of all tree angles of a triangle is always 180°
90° are given with the little square, 60 by the similar reasoning as above
Answer:
Step-by-step explanation:
L an M are parallel & P is transversal.
So, 120, x are co-interior angles, ie 180
x +120 = 180
x = 180 - 120
x = 60
The angle vertically opposite to x, will have the same value of x.
Vertically opposite angles are equal
In triangle, sum of angles = 180
60 + 90 + y = 180
150 + y =180
y =180 - 150
y =30
Can someone answer this question please please help me I really need it if it’s correct I will mark you brainliest .
Answer:
14.13
Step-by-step explanation:
Step 1) Find the total area
A = pi x r^2
A = pi x 3^2
A = 9pi
Step 2) Divide the total area by 4
9pi / 4 = 2.25pi
2.25pi = 7.07
A = 7.07 square feet
Hope this helps! :)

Alex is drawing rectangles with different areas on a centimeter grid . He can draw 3 different rectangles with an area of 12cm squared how many different rectangles could Alex draw with an area of 11 cm squared give a reason for your anwser please i need help please anwser this quikly.
Answer:
Number of rectangles could alex draw with an area of 11cm² = 1
Step-by-step explanation:
Minimum length in centimeter grid = 1 cm
Alex is drawing rectangles with different areas on a centimetre grid.He can draw 3 different rectangles with an area of 12cm²
That is
[tex]12 = 1 \times12\\\\12=2\times6\\\\12=3 \times4[/tex]
These are the 3 different rectangles with an area of 12cm².
Now we need to find how many rectangles could alex draw with an area of 11cm².
11 = 1 x 11
So only one factorization is possible.
Number of rectangles could alex draw with an area of 11cm² = 1
Answer:
Alex can only drawn 1 rectangle with an area of 11 cm²
Step-by-step explanation:
When Area = 12 cm², Alex could draw 3 rectangles.
This is because, Area of a rectangle = Length * Breadth
and the factors of 12 are 1, 2, 3, 4, 6, and 12.
The 3 triangle formed can be gotten from the correct combinations of these factors, which are 12 × 1, 2 × 6, 3 × 4.
All of these three combinations give us an area of 12 cm²
Similarly when Area = 11 cm², 11 is a prime number and its factors are 1 and 11.
The only combination that can be made from these factors is 11 × 1.
This means that only one rectangle can be drawn

An amusement park ride is made up of a large circular frame that holds 50 riders. The
circumference of the frame is about 138 ft. What is the diameter of the ride? Round to the nearest
tenth.
Help Please
Answer:
The diameter of the ride is 44 feets.
Step-by-step explanation:
We have,
The circumference of the frame is about 138 ft.
It is required to find the diameter of the ride.
The circumference of means that the outer covering of the circle. It is given by the formula as follows:
[tex]C=2\pi r[/tex]
r is radius
Since, 2r = d, diameter of circle
[tex]C=d\pi \\\\d=\dfrac{C}{\pi}\\\\d=\dfrac{138}{3.14}\\\\d=43.94\ ft[/tex]
or
d = 44 feets
So, the diameter of the ride is 44 feets.
if a number is randomly chosen from the following list what is the probability that the number is a multiple of 5?
{32, 49, 55, 30, 56, 28, 50, 40, 40, 45, 25}
Answer:
7/11
Step-by-step explanation:
There are 11 numbers with only 7 numbers with a multiple of 5.
Answer:
7/11
Step-by-step explanation:
first, you must determine which numbers are multiples of five. multiples of five are numbers 5 or greater that end in 0 or 5. for example, 5,10,15,20,25... . from this list, you can tell that 7 of these numbers are multiples of 5 : 55,30,50,40,40,45,25 . Next, you count the total amount of numbers. there are 11 numbers in the list. so, the probability of randomly choosing a multiple of 5 is 7/11 :)
find a rational number between 3 and 4
Answer:
3.1, 3.2, 3.3
Step-by-step explanation:
There are infinite options but a rational number is a fraction, decimal, or repeating decimal.
3 [tex]\frac{1}{3}[/tex] is an example of a fraction between 3 and 4
3.2 is an example of a decimal between 3 and 4
3.3333333... is an example of a repeating decimal between 3 and 4
Answer: 3.2526252625...
Explanation: The number above would be a rational number because it's a repeating decimal. Notice that in the decimal above, 2526 is a group of repeating digits and repeating decimals are rational.

An arc subtends a central angle measuring \dfrac{3\pi}{5} 5 3π start fraction, 3, pi, divided by, 5, end fraction radians. What fraction of the circumference is this arc?
Answer:
[tex]\dfrac{3}{10}[/tex]
Step-by-step explanation:
Length of an arc[tex]=\dfrac{\theta}{2\pi}X 2\pi r=\theta r[/tex]
If the central angle of the arc is [tex]\dfrac{3\pi}{5}[/tex]
Length of an arc[tex]=\dfrac{3\pi r}{5}[/tex]
Therefore:
Ratio of the length of the arc to the circumference
[tex]=\dfrac{3\pi r}{5}:2\pi r\\=\dfrac{3\pi r}{5*2\pi r}\\=\dfrac{3}{10}[/tex]
Therefore, the arc is [tex]\dfrac{3}{10}[/tex] of the circumference is this arc.
