The shapes which have all the properties shown are C. Rectangle and E. Square.

Isosceles triangles are defined as the triangles for which two sides or two angles are equal to each other.

Given properties are,

At least 2 sides of equal length

2 pairs of parallel sides

At least 2 right angles

Since the property includes that 2 pairs of parallel sides, it must contain 4 sides in total.

So triangle can't be a possible shape.

Parallelogram can't also be possible since there are no right angles.

Only right trapezoids are possible since the other ones will not have al least two right angles.

Rectangle and square are possible.

Hence the correct shapes are Rectangle and Square.

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.

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

Answer:

(a) 18.5ft

(b) 388.5 ft²

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

Answer:

D 0.2

Step-by-step explanation:

YES THIS IS RIGHT

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

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.

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

B. 28, 7, 36, 8, 17

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

Median: 17

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

Step-by-step explanation:

The probability that the advertisement is a social media ad and has an odd number is 1/13.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given that, A local business had various advertising campaigns. It had television ads numbered 1,2,3,4,5,6, newspaper and magazine ads numbered 1,2,3,4,5, and social media ads labeled 1,2.

We need to find If a single advertisement campaign is picked at random, what is the probability that the advertisement is a social media ad AND has an odd number,

Probability = favorable outcomes / possible outcomes

Number of social media ads with an odd number = 1

Total number of ads = 13

We know that,

P(that the advertisement is a social media ad AND has an odd number)

= 1/13.

Hence, the probability that the advertisement is a social media ad and has an odd number is 1/13

Step-by-step explanation:

[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).

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).
