Answer:
P(at least one Heart)= 37/64
Step-by-step explanation:
Number of cards in the Deck=52
Number of Hearts=13
Number of Non-Hearts Card=52-13=39
Since we require the probability that the person will get at least one heart, we can first find the probability that the person will not pick a heart out of the three cards and find its complement.
P(Picking three Non Heart Cards)=39/52 X 39/52 X 39/52 =27/64
Therefore:
P(at least one Heart)=1-27/64=37/64
To find the probability of getting at least one heart when selecting 3 cards with replacement from an ordinary deck, subtract the probability of not getting any hearts from 1.
Explanation:To calculate the probability that the person will get at least one heart, we need to find the probability of getting no hearts and subtract it from 1. There are 52 cards in a deck and 13 of them are hearts. So, the probability of not getting a heart on the first draw is 39/52, on the second draw is also 39/52, and on the third draw is again 39/52. Multiply these probabilities together to get the probability of not getting a heart in any of the three draws. Finally, subtract this probability from 1 to find the probability of at least one heart.

Often in statistics research, a population is too large to collect data on. A sampling distribution of a statistic is created by taking repeated samples of a certain size. But the most accurate information will be gained by taking every possible sample of a certain size.
A population of size 4 has 6 possible samples of size 2. Use this fact to explain why taking every sample of a certain size is not done for a population too large to analyze.
Final answer:
For large populations, taking every possible sample of a certain size becomes unfeasible due to the rapidly increasing number of combinations. Hence, random sampling methods are used to capture the population characteristics in a practical way, with larger samples providing more reliable statistics.
Explanation:
When a population size is large, it becomes impractical to take every sample of a certain size due to the combinatorial explosion in the number of potential samples. For instance, with a population of size 4, there are 6 possible samples of size 2, which is manageable. However, as the population size increases, the number of possible samples grows astronomically, making it unfeasible to examine them all. This is why sampling is a vital technique.
Random sampling methods like simple random sampling, stratified sampling, cluster sampling, and systematic sampling are employed to ensure each individual has an equal chance of being selected, which helps in capturing the characteristics of the entire population in the sample. Larger sample sizes are generally preferred as they reduce sampling variability and provide more reliable statistics.

A rectangle has a height of 6k^3 and a width of 2k^2 + 4K +5 what is the area
Answer:
The answer is 12k^5+24k^4+30k^3.
Step-by-step explanation:
You want to multiply the height by width to find area. Multiply 6k^3 times 2k^2+4k+5. 6k^3(2k^2+4k+5)= 12k^5+24k^4+30k^3.
Final answer:
The area of a rectangle with a height of 6k³ and a width of 2k² + 4k + 5 is calculated by multiplying the height by the width, resulting in 12k⁵ + 24k⁴ + 30k³.
Explanation:
To calculate the area of a rectangle, you multiply the height by the width. The given height of the rectangle is 6k³ and the width is 2k² + 4k + 5. Applying the formula for the area of a rectangle, we have:
A = height × width
A = 6k³ × (2k² + 4k + 5)
To find the area, distribute the height into each term of the width:
A = (6k³ × 2k²) + (6k³ × 4k) + (6k³ × 5)
A = 12k⁵ + 24k⁴ + 30k³
The area of the rectangle is 12k⁵ + 24k⁴ + 30k³.

3 x minus 4 y = 16. 2 x + 3 y = 5.
(–4, 1)
(4, –1)
(–4, –1)
(4, 1)
Answer:
(4, -1)
Step-by-step explanation:
3 x minus 4 y = 16
2 x + 3 y = 5
3x - 4y = 16
2x + 3y = 5
x = 2.5 - 1.5y
3(2.5 - 1.5y) - 4y = 16
7.5 - 4.5y - 4y = 16
-8.5 = 8.5y
y = -1
x = 2.5 - 1.5(-1)
x = 2.5 + 1.5
x = 4
(4, -1)
The solution to the system of equations 3x - 4y = 16 and 2x + 3y = 5
is (4, - 1).
What are the three types of solutions of a linear system of equations?If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.
There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.
Given, A system of linear equations 3x - 4y = 16 and 2x + 3y = 5.
Multiplying equation (i) by 2 and equation (ii) by 3 we have,
6x - 8y = 32 and 6x + 9y = 15.
Subtracting equation (iii) from (iv) we have,
9y + 8y = 15 - 32.
17y = - 17.
y = -1 and, 6x - 8(-1) = 32 ⇒ 6x + 8 = 32 ⇒ 6x = 24 ⇒ x = 4.
So, The solution to the system of equations is (4, - 1).

What is the nth term rule of the linear sequence below? 15 , 7 , − 1 , − 9 , − 17 , . . .
The nth term rule of the given linear sequence is -8n + 23. It follows the pattern of subtracting 8 from the previous term. So, each term in the sequence is obtained by -8n + 23.
Explanation:The nth term rule of the given linear sequence is -8n + 23.
To find the nth term rule, we can observe that each term is obtained by subtracting 8 from the previous term. Therefore, the sequence follows the pattern:
1515 - 8 = 77 - 8 = -1-1 - 8 = -9-9 - 8 = -17and so on
So, we can generalize the sequence as -8n + 23, where n represents the position of the term in the sequence.

The three inside angles (a,b and c) of a right-angled triangle are in the ratio 7:18:11
the smallest angle is 35 degrees
workout angles a,b and c
Answer:
The three angles of the right-angled triangle are
a = 35°
b = 90°
c = 55°
Step-by-step explanation:
We are given the ratio of angles of a right-angled triangle
a:b:c = 7:18:11
Recall that the sum of interior angles in a right-angled triangle is always 180°
7x + 18x + 11x = 180
36x = 180
x = 180/36
x = 5
a:b:c = 7x:18x:11x
a:b:c = 7(5):18(5):11(5)
a:b:c = 35:90:55
a = 35°
b = 90°
c = 55°
Alternatively:
We are given that the smallest angle is 35°
a = 7x = 35
x = 35/7
x = 5
b = 18x
b = 18(5)
b = 90°
c = 11x
c = 11(5)
c = 55°
Answer:
Step-by-step explanation:
solution
sum of angles on a triangle=180
total ratio=7+18+11=36
for angle a: (7/36)x180=35°
for angle c: (11/36)x180=55°
for angle b: (18/36)x180=90°
therefore: the 3 angles are 35°, 90°, 55°.

Chrissy went to the grocery store Thursday night and spent $22.54. She paid
$3.22 for three fruit bars. The remainder of the food was for a party she
planned to give on Friday night. How much did she spend on food for the party?
Answer:
19.32
Step-by-step explanation:
The amount Chrissy spent on food for the party is determined by subtracting the cost of the fruit bars, $3.22, from her total amount spent, $22.54. This leads to a result of $19.32.
Explanation:The subject of this question is Mathematics, specifically subtraction. To figure out how much Chrissy spent on food for the party, you have to deduct the cost of the three fruit bars from the total amount she spent that day.
Given:
Total amount spent by Chrissy = $22.54
Cost of three fruit bars = $3.22
By subtracting the amount she spent on the fruit bars from the total amount:
Amount spent on the party = Total amount spent - Cost of the fruit bars
Thus, Amount spent for the party = $22.54 - $3.22 = $19.32
Therefore, Chrissy spent $19.32 on food for the party.

64−(3y+8y+y)÷40=37
Answer:
y= 90
Step-by-step explanation:
64−(3y+8y+y)÷40=37
Combine terms in the parentheses
64−(12y)÷40=37
Subtract 64 from each side
64-64−(12y)÷40=37-64
-(12y)÷40=-27
Multiply each side by 40
-(12y)÷40*40=-27*40
-12y =-1080
Divide each side by -12
-12y/-12 = -1080/-12
y =90
Answer:
y= 90
Step-by-step explanation:
64−( 3y+8y+y 40 )=37 64+ −3 10 y=37 −3 10 y+64=37
Step 2: Subtract 64 from both sides.
−3 10 y+64−64=37−64 −3 10 y=−27
Step 3: Multiply both sides by 10/(-3).
( 10 −3 )*( −3 10 y)=( 10 −3 )*(−27) y=90
