Answer:
y+7=4(x-1)
Step-by-step explanation:
y-y₁=m(x-x₁)
m= 4
y- -7 = 4(x-1)
y+7=4(x-1)

A.The mean is about 3.1; there are no gaps or outliersa peak at 2; and the data is not symmetrical.
B. The median is 2.5; the distribution is symmetrical; and there are no gaps or outliers.
C.The range is 7there is a peak at 5; and 6, 7and are outliers
D. The mode is 2; the data is skewed to the right; and there is a gap from 3-4
Answer:
B The median is 2.5; the distribution is symmetrical; and there are no gaps or outliers.
Step-by-step explanation
when I find the median it gets to 2, 3 so I get 2.5 no gaps and 0-7 isn't that far

The lenght of a rectangle is 2 units more than the width. The area of the rectangle is 48 units. What is the length, in units, of the rectangle?
Answer:
The length of this rectangle is 6 units.
Step-by-step explanation:
Let the width of the rectangle be x.
x • (x+2) = 48
x^2+2x=48
x^2+2x-48=0
x^2 - 6x + 8x - 48
x(x-6) 8(x-6)
(x+8)(x-6)
x=-8,6
Answer:
6+2=8 units..............

2. Solve 3^4x-5 = (1/27)^2x+10 for x. Show your work
I know it equals around the negatives but that's it
It looks like the equation is supposed to read
3⁴ˣ ⁻ ⁵ = (1/27)²ˣ ⁺ ¹⁰
Recall that 3³ = 27, so 1/27 = 3⁻³ :
3⁴ˣ ⁻ ⁵ = (3⁻³)²ˣ ⁺ ¹⁰
Distribute the exponent on the right side:
3⁴ˣ ⁻ ⁵ = 3 ⁻⁶ˣ ⁻ ³⁰
The exponents must be equal for this equation to hold, so
4x - 5 = -6x - 30
Solve for x :
10x = -25
x = -25/10 = -5/2
What is the area of this figure
So you basically have to find the area as if it were a rectangle, which would be 19*13, which is 247. Then, you find the area of the corner taken out and subrtact it, so 3*4 is 12, and 247-12 is 235.
In circle E with m \angle DEF= 70m∠DEF=70 and DE=13DE=13 units find area of sector DEF. Round to the nearest hundredth.
Answer:
103.18units³
Step-by-step explanation:
Area of the sector DEF = theta/360 * πr²
r is the radius
theta is the angle subtended at the centre
theta =70 degrees
radius DE = 13units
Substitute
Area of the sector = 70/360 * 3.14(13)²
Area of the sector = 7/36 * 530.66
Area of the sector = 3,714.62/36
Area of the sector = 103.18units³ (to the nearest hundredth)
Answer: 103.24

Megan and her little sister, Nora, counted their Halloween candy after trick-or-treating. They love taffy and wanted to know who collected more taffy pieces compared to the rest of the candy. In Megan's bag, 20 out of the 50 candy pieces were taffy. In Nora's bag, 11 out of the 25 pieces were taffy. Who got the greater ratio of taffy to total candy pieces?
Answer:
Nora
Step-by-step explanation:
M 20 : 50 = 2/5
N 11/25
2/5 = 10/25 < 11/25

What is the surface area of this cylinder?
Answer:
1067.6 m²Step-by-step explanation:
Given that
r = 10 mh = 7 mπ ≈ 3.14Find the surface area of the cylinder!
Equation =
2πr × (r+h) =(2 × 3.14 × 10) × (10 + 7) =
62.8 × 17 ≈
1067.6 m²The surface area of the cylinder ≈ 1067.6 square metres
_________________
#Indonesian - kexcvi
Answer:
Use this formula to calculate for the surface area of cylinder.
Step-by-step explanation:
A=2π r h+2 π r^2.
use r = 10 m and h = 7 m
2 (3.14) (10) 7 + 2 (3.14) 10 ^2. = 439.6 + 628 = 1067.6
round to the nearest hundredths = 1068
