hello,
Step-by-step explanation:
negative and negative when we add is + so as 3 will turn into positive ,
1+3= 4
and as -5 is in negative positive + negative is negative , so we need to subtract ,
4-5= -1.

The boys basketall team averages 52 points per game with a standard deviation of 7.0 points. What is the probability that the boys will score between -1.2 and 2.0 standard deviations of their average?
Answer:
0.6832
Step-by-step explanation:
Given :
Mean, m = 52
Standard deviation, s = 7
-1.2 standard deviation of average = 57 - 1.2(7) = 57 - 8.4 = 48.6
2 standard deviations of average = 57 + 2(7) = 57 + 14 = 71
Zscore = (48.6 - 52) / 7 = - 0.486
Zscore = (71 - 52) / 7 = 2.714
P < -0.486) = 0.31348
P < 2.714 = 0.99668
P < 2.714 - P < -0.486 = (0.99668 - 0.31348) = 0.6832

1 - 1/4 - 3/5 = area shaded
1 - 5/20 - 12/20 = area shaded
1 - 17/20 = area shaded
3/20 = area shaded
Another method:
1 - 0.25 - 0.6
1 - 0.85 = 0.15

THIS IS exact and approximate pi PLS HELP ME BEFORE I FAIL
Answer:
Approximate: C ≈ 50.27
Exact: C = 16π
Step-by-step explanation:
C = 2πr
We know that r is 8
C = 2π8
C = 16π
C ≈ 50.27
The circumference of a circle is 16π unit²
What is circumference of a circle?The circumference of a circle is defined as the linear distance around of circle.
Formula of circumference of a circle (C) = 2πr
Where r is radius of circle
Given radius of circle (r) = 8,
Substitute the value of r,
C = 2π(8)
C = 16π unit²
Substitute π = 3.14,
C ≈ 50.27 (approximate)
Thus, the circumference of a circle is 16π unit²

A circle has a circumference of 615.44 point, 44 units.
What is the radius of the circle?
The circumference of a circle is equal to C=2πr
From the question, we have 615.44.
Assume that pi is equal to 3.14
Substitute and solve for r
615.44= 2(3.14)r
r= 615.44/ 6.28
r=98.4704
r=98
Therefore, the radius is about 98 units.
To check:
C=2πr
C=2 x 3.14 x 98
C=6.28 x98
C=615.44
Classify the polygon: Coordinates: A(1, 4), B(4, 5), C(5, 2) Explain your answers. Must show all work to support your reasoning. a. Classify ∆ABC as equilateral, isosceles, or scalene. Explain your reasoning. b. Determine if ∆ABC is a right triangle. Explain your reasoning. c. Find the perimeter and area of ∆ABC. Round decimal answers to the nearest tenth.
Answer:
a. ΔABC is an isosceles triangle
b. ΔABC is a right triangle
c. The perimeter of ΔABC is approximately 10.8
Step-by-step explanation:
The given vertices of the polygon, are;
A(1, 4), B(4, 5), C(5, 2)
By observation of the differences of the coordinates of the given points, the points are non-linear, as the rate of increase in the y-values, for a given increase in the x-value, is not constant
The length of segments of the triangle ΔABC are found using the formula for finding the distance, 'd', between points given their coordinates, (x₁, y₁), (x₂, y₂), as follows;
[tex]d = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
The length of segment, [tex]\overline {AB}[/tex] = √((5 - 4)² + (4 - 1)²) = √10
The length of segment, [tex]\overline {AC}[/tex] = √((2 - 4)² + (5 - 1)²) = √20
The length of segment, [tex]\overline {BC}[/tex] = √((2 - 5)² + (5 - 4)² = √10
The length of segment, [tex]\overline {AB}[/tex] = The length of segment, [tex]\overline {BC}[/tex], therefore, ΔABC is an isosceles triangle by definition of an isosceles triangle which is a triangle that have two sides of equal length
ΔABC is an isosceles triangle
b. According to Pythagoras' theorem, the sum of the squares of the two shorter sides (the legs) of a right triangle = The square of the length of the longest side
In if triangle ΔABC is a right triangle, we should have;
[tex]\overline {AB}[/tex]² + [tex]\overline {BC}[/tex]² = [tex]\overline {AC}[/tex]²
Checking gives;
(√10)² + (√10)² = 10 + 10 = 20 = (√20)²
Whereby [tex]\overline {AB}[/tex]² (= (√10)²) + [tex]\overline {BC}[/tex]² (= (√10)²) = (√20)² = [tex]\overline {AC}[/tex]², ΔABC is a right triangle
ΔABC is a right triangle
c. The perimeter of ΔABC = The length of segment, [tex]\overline {AB}[/tex] + The length of segment, [tex]\overline {AC}[/tex] + The length of segment, [tex]\overline {BC}[/tex]
∴ The perimeter of ΔABC = √10 + √10 + √20 ≈ 10.7966912753
By rounding off to the nearest tenth, the perimeter of ΔABC ≈ 10.8.

Find the value of each variable
Answer:
z = 77
y = 103
Step-by-step explanation:
The angle where 103 and z meet is supplementary, which means it is 180. Since we know one side is 103, we just have to subtract this value from 180 to find the other side, 77.
The total angle measure of a trapezoid is 360. Since we have all the values now except for one, we can simply add them all together: 95 + 77 + 85 = 257. Then, subtract this number, 257, from 360, to get the final angle measure as 103.

Un joyero tiene forma de un prisma con base hexagonal tiene una altura de 3cm y un volumen de 67.5cm3 cual es el area de su base ??
Answer:
22.5 cm²
Step-by-step explanation:
La fórmula para el volumen de un prisma con una base hexagonal = Área de la base × Altura
De la pregunta anterior
Área de la base =?
Altura = 3 cm
Volumen = 67.5 cm³
Área de la base = Volumen ÷ Altura
Área de la base = 67.5 cm³ ÷ 3cm
= 22.5 cm²
Por lo tanto, el área si es base = 22.5 cm²
show that (X+1)(x+3)(x+5) can be written in the form ax^3+bx^2+cx+d
Answer:
(x+1)(x+3)(x+5) = x^3 + 9 x^2 + 23 x + 15
Step-by-step explanation:
If you apply the distributive property, you can expand the expression to x^3 + 9 x^2 + 23 x + 15, from that you can see that:
a = 1
b = 9
c = 23
d = 15
And with these values, ax^3+bx^2+cx+d completely equals the given expression.

A company sells fruit smoothies in two sizes: 6 ounces and 12 ounces. You know that a 6-ounce bottle contains 96 milligrams of sodium. If the amount of sodium is directly proportional to the fluid ounces of smoothie, how many milligrams of sodium does a 12-ounce bottle contain?
And can yall put an explanation please
Answer:
I believe it would be 192 milligrams.
Step-by-step explanation:
They said the amount of sodium is equal to the amount of ounces meaning it would be 6ounce:96milligrams. In this case, doubling 6 would be 12, resulting in doubling 96 as well. I'm not 100% sure, this problem contains an unnecessary amount of information for a simple concept.
12 ounces smoothies has 192 milligrams sodium
Given : 6 ounces smoothies have 96 milligrams of sodium
So, per ounce of smoothie consists 96 / 6 = 16 milligrams of sodium
To find : milligrams of sodium in 12 ounces of smoothies
According to sodium per unit smoothie, 12 ounces smoothie consist 12 x 16 = 192 milligrams sodium.
Also : Doubling 6 ounces smoothies to 12 ounces, we get 192 milligrams of sodium by doubling 96 milligrams.

The hole for a support needs to be 5 feet deep. It is currently 1 foot and 9 inches deep. How much deeper must the hole be
Answer:
3 foot 3 inches
Step-by-step explanation:
How much deeper the hole should be = intended depth - current depth
Convert feet to inches for easy calculation
1 ft = 12 inch
5 x 12 = 60 inches
1 foot = 12
12 + 9 = 21 inches
60 - 21 = 39 inches
convert inches to feet
39 /12 = 3 feet 3 inches

First, you should take 30% of the original price, which would be 600. (You should be able to use a standard calculator for this). Next, since the price increases by 30%, just put 600+30% and your answer should be 780.
PS I just tried this problem on my calculator, so I don't know if I did it right, but it makes sense to me. I also searched it up and it also says it's 780, so I'm guessing it's correct. The way I showed you is easier though.
