The true number sentence is the third option:
6.8*1.3 = 8.84
Which number sentence is true?
Here we have number sentences of the form:
A*B = C
This is true only when the value of the product A*B is equal to the value of C.
One key thing to identify the correct one is remembering the rule of signs:
(+)*(-) = (-)
(+)*(+) = (+)
(-)*(+) = (-)
(-)*(-) = (+).
The only option that meets that rule is:
6.8*1.3 = 8.84
Where the product of two positive numbers gives another positive number (and the equality is true) so we conclude that this number sentence is true.

A game has a spinner with 8 equal- sized sections. The results of 450 spins are shown in the table. Part Frequency 1 58 2 52 3 39 4 77 5 50 6 43 7 60 8 71
For which number is the experimental probability closest to the theoretical probability
Using it's concept, it is found that the experimental probability is closest to the theoretical probability for number 1.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
The theoretical probability is calculated before any experiments, while the experimental probability is calculated after experiments.
Considering that the sections are equal-sized, the expected frequency for each section is given by:
Ef = 450/8 = 56.25.
The closest frequency to 56.25 is of 58, associated with number 1, which is the one that has the closest probabilities.

Answer:
just know total angle sum is 180°
Step-by-step explanation:
[tex]52 + (15x + 3) + (3x - 1) = 180 \\ 52 + 3 - 1 + 15x + 3x = 180 \\ 54 + 18x = 180 \\ 18x = 180 - 54 \\ 18x = 126 \\ x = 7[/tex]

Answer:
x = 7
Step-by-step explanation:
→ Find the sum of the angles
52 + 15x + 3 + 3x - 1 = 18x + 54
→ Wquate the expression to 180
18x + 54 = 180
→ Solve for x
x = 7

The net of an isosceles triangular prism is shown. What is the surface area, in square units, of the triangular prism?
104 units2
132 units2
152 units2
168 units2
Answer: Last option is correct.
Since we have given that
Dimension of central rectangle is 6 units by 7 units
So, Area of central rectangle is given by
Dimensions of upper and lower rectangle are as follows:
Length = 5 units
Breadth = 7 units
Area of upper and lower rectangle is given by
Similarly, dimensions of two triangles are as follows:
Height = 4 units
Base = 6 units
So, Area of two triangles is given by
Hence, Total surface area of the net of an isosceles prism is given by
Therefore, Last option is correct.
Answer:
152 units²
Step-by-step explanation:
Surface Area :
Area (2 triangles) + Area (2 rectangles) + Area (middle rectangle)2 x 1/2 x 6 x 4 + 2 x 8 x 5 + 8 x 624 + 80 + 4880 + 72152 units²What is the inverse of the function f(x) = x 3? h(x) = one-thirdx 3 h(x) = one-thirdx – 3 h(x) = x – 3 h(x) = x 3

White the equation of the circle with center -7,4 and diameter 12
Answer: (x -4)^2 +(y -7)^2 = 36
Step-by-step explanation: The equation of a circle with radius r and center at (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
When the diameter is 12, the radius is 6 (half the diameter). Then for your center point, the equation is ...
(x -4)^2 +(y -7)^2 = 36

A bucket can hold a total of 5 gallons. If the bucket is 45% full, how much water is in the bucket?
The question is an illustration of volume, and the amount of water in the bucket at 45% full is 2.25 gallons
How to determine the amount of water?The capacity of the bucket is given as:
Bucket = 5 gallons
At 45% full, we have:
Capacity = 45% * 5 gallons
Evaluate the product
Capacity = 2.25 gallons
Hence, the amount of water in the bucket at 45% full is 2.25 gallons
