Which ordered pair is in the solution set of 0.5x - 2y ≥ 3?

Answers

Answer 1

Answer:

Step-by-step explanation:

The answer is c because when 2, -1 is plugged into the equation, you get

.5(2) - 2(-1) >/= 3

when solved -

1 + 2 >/= 3 -

3 >/= 3

and this is in the solution set because three is equal than or greater to three

Why 117+3 = 5! is correct

Answers

Answer:

5!= 5×4×3×2×1

117+3=120

5×4×3×2×1= 120

therefore 117+3=5! is correct

The statement 117+3 = 5! is correct because;

The left hand side and right hand side give the same solution of 120.

We want to find out why 117 + 3 = 5! is correct.

Let us first find the left hand side of the equation;

117 + 3 = 120

Now, for the right hand side, 5! simply means 5 factorial.

Factorial of a number is a term used in maths to denote the product of all

positive integers less than or equal to that number. For example; n!. That is

factorial and it means the product of all positive integers below n.

Let's apply the concept of factorial to 5!.

All positive integers less than or equal to 5 are; 5, 4 , 3, 2, 1

Thus; 5! = 5 × 4 × 3 × 2 × 1 = 120

This 5! = 120 and it is the same as 117 + 3 = 120. Thus the given statement in the question is true.

A. 0.1
B. 0.3
C. 0.4

Answer:

Step-by-step explanation:

YES THIS IS RIGHT

The required, mean of the sample proportions would approach is 0.2.

What is a normal distribution?

Normal distributions can be altered to standard normal distributions by the formula:

Z = (X - μ)/σ

As the size of each sample increases, the mean of the sample proportions would approach the population parameter, which in this case is 0.2. This is known as the central limit theorem.

Therefore, the answer is D. 0.2.

Which set of data has the smallest difference between the mean and the median?

OD 23, 36, 25, 38, 30

Answers

Answer:

D 23, 36, 25, 38, 30

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is the sum of all it's values divided by the number of values.

Median of a data-set:

The median of a data-set is the value that separates the lower 50% from the upper 50% on the ordered set.

If the cardinality n is odd, as in this case, the median is the element at the position (n+1)/2. Since in this case, n = 5, the median is the 3rd element in the ordered set.

A 13, 42, 17, 26, 38

Ordered set: 13, 17, 26, 38, 42

Median: 26

Mean: (13+17+26+38+42)/5 = 27.2

Difference: 27.2 - 26 = 1.2

B. 28, 7, 36, 8, 17

Ordered set: 7, 8, 17, 28, 36

Median: 17

Mean: (7+8+17+28+36)/5 = 19.2

Difference: 19.2 - 17 = 2.2

C 14, 29, 38, 7, 13

Ordered set: 7, 13, 14, 29, 38

Median: 14

Mean: (7+13+14+29+38)/5 = 20.2

Difference: 20.2 - 14 = 6.2

Step-by-step explanation:

(a)

She has 79ft of fence = the perimeter will be 79.

Perimeter of a rectangle = 2(length) +2(width)

79 = 2(21)+2(width)

2(width) = 79 - 42

width = 37/2

width = 18.5ft

(b)

Area of a rectangle = (length)(width) = (21)(18.5) = 388.5 ft²

[tex]range = (3,7,1) - (9,6,7) \\ = ( - 6,1, - 6) \\ distance = \sqrt{ {x}^{2} + {y}^{2} + {z}^{2} } \\ = \sqrt{ {( - 6)}^{2} + {1}^{2} + {( - 6)}^{2} } \\ = \sqrt{73} \\ = 8.5 \: units[/tex]

The distance between points (3,7,1) and (9,6,7) is 8.54 units and the midpoint of the segment is (6, 6.5, 4).

What is Distance?

The length along a line or line segment between two points on the line or line segment.

Distance=√(x₂-x₁)²+(y₂-y₁)²

We need to find the distance between points (3,7,1) and (9,6,7).

Distance=√(9-3)²+(6-7)²+(7-1)²

=√6²+(-1)²+(6)²

=√36+1+36

=√73

=8.54 units

So the distance between the two points is approximately 8.5 units.

To find the midpoint of the segment between the two points, we use the midpoint formula:

midpoint = ((x₁+x₂)/2, (y₁+y₂)/2, (z₁+z₂)/2)

Using the given points, we have:

midpoint = ((3+9)/2, (7+6)/2, (1+7)/2)

= (6, 6.5, 4)

So the midpoint of the segment is (6, 6.5, 4).

Hence, the distance between points (3,7,1) and (9,6,7) is 8.54 units and the midpoint of the segment is (6, 6.5, 4).

Marcia is mixing lemonade. She use 3 parts water to 1 part syrup. If she has 9 parts water, how much syrup will she need to complete the mixture?

Answers

Answer:

if Marcia uses 9 parts water, that mean she will have to use 3 parts syrup

Step-by-step explanation:

this is ratios,

so to find out how many syrup she needs, you need to see how much she used water from the original recipe

so:

9 ÷ 3 = 3

so she multiplied three to get to nine, so we have to do the same to the syrup

_ ÷ 1 = 3

or:

3 × 1 = 3

so the answer is 3
