It is kinda like she said There are two perpendicular lines with an x horizontal and y vertical axis. i think that is in your math book as well

I'm assuming you mean Cartesian plane. It is the same as a coordinate plane. There are two perpendicular lines with an x (horizontal) and y (vertical) axis.

So there was a total of 28 games played and the Houston Tigers only scored above 53 points 4 times. Now the fraction would be 4/28 but we have to reduce so the real answer is actually 1/7

Could you help me with this? I am very bad at math i need help

Answer:

10) 7 meters

11) 10 yards

12) 452.16 inches²

13) 235.5 meters²

14) 22608 centimeters²

15) 4220.16 centimeters²

16) 1177.5 centimeters²

17) 141.3 millimeters²

Step-by-step explanation:

10) The volume of a rectangular prism is calculated by multiplying the height, width, and length of the shape. In this question, we have the volume, the width, and height, but not the length. To find it, we can divide the width and height from the volume.

First, divide the width.

$\frac{210}{5}$ = 42

Next, the height.

$\frac{42}{6}$ = 7

The length of the shape is 7 meters.

----------------------------------------------------------------------------------------------------------------

11) For this question, we can do the same thing. Take the volume, then divide the length and width from it.

$\frac{360}{6}$ = 60

$\frac{60}{6}$ = 10

The height is 10 yards.

----------------------------------------------------------------------------------------------------------------

12) We have to find the volume of a cylinder. The formula for this is $V=\pi r^2h$ . We will use 3.14 for pi. The radius is 4 in and the height is 9 in. We can plug our values into the equation and solve.

V = $\pi$ r²h

V = $\pi$ (4²)(9)

V = 3.14(4²)(9)

V = 50.24(9)

V = 452.16

The volume is 452.16 inches².

----------------------------------------------------------------------------------------------------------------

13) We will use the same formula for this. Our radius is 5 m and the height is 3 m. Plug the values in and solve.

V = $\pi$ r²h

V = $\pi$ (5²)(3)

V = 3.14(5²)(3)

V = 78.5(3)

V = 235.5

The volume of this cylinder is 235.5 meters².

----------------------------------------------------------------------------------------------------------------

14) The radius of this cylinder is 15 cm. The height is 32 cm. Put these numbers into our formula.

V = $\pi$ r²h

V = $\pi$ (15²)(32)

V = 3.14(15²)(32)

V = 708.5(32)

V = 22608

The volume of this cylinder is 22608 centimeters².

----------------------------------------------------------------------------------------------------------------

15) The next cylinder has a radius of 8 cm and a height of 21 cm.

V = $\pi$ r²h

V = $\pi$ (8²)(21)

V = 3.14(8²)(21)

V = 200.96(21)

V = 4220.16

The cylinder has a volume of 4220.16 centimeters².

----------------------------------------------------------------------------------------------------------------

16) This cylinder has a radius of 5 cm and a height of 15 cm.

V = $\pi$ r²h

V = $\pi$ (5²)(15)

V = 3.14(5²)(15)

V = 78.5(15)

V = 1177.5

The volume is 1177.5 centimeters².

----------------------------------------------------------------------------------------------------------------

17) The dimensions of this cylinder are 3 mm and 15 mm.

V = $\pi$ r²h

V = $\pi$ (3²)(15)

V = 3.14(3²)(15)

V = 9.42(15)

V = 141.3

The volume is 141.3 millimeters².

----------------------------------------------------------------------------------------------------------------

What is the area of a sector with measure of arc equal to 90Á and radius equal to 1 foot? 0.25pi sq. ft. 0.5pi sq. ft. pi sq. ft

Semmy [17]

Given a circle with radius r = 8 and a sector with subtended angle measuring 45°, find the area of the sector and the arc length.

They've given me the radius and the central angle, so I can just plug into the formulas. For convenience, I'll first convert "45°" to the corresponding radian value of π/4:

A = ((pi/4)/2)(8^2) = (pi/8)(8^2) = 8pi, s = (pi/4)(8) = 2pi

area A = 8π, arc-length s = 2π
Given a sector with radius r = 3 and a corresponding arc length of 5π, find the area of the sector.

For this exercise, they've given me the radius and arc length. From this, I can work backwards to find the subtended angle.
Then I can plug-n-chug to find the sector area.
5pi = (theta)(3), (theta) = (5/3)pi So the central angle is (5/3)π.
Then the area of the sector is:
A = ((5/3)pi / 2)*(3^2) = ((5/6)pi)*(9) = (15/2)pi A = (15 pi) / 2

90/360 = 0.25 pi sq ft

According to a survey conducted by Netpop Research, 65% of new car buyers use online search engines as part of their car-buying

11111nata11111 [884]

Answer:

(a) 0.76

(b) 0.46

(c) 0.58

Step-by-step explanation:

Let's first list the probabilities of each event:

Buyers using online search engine: 0.65

Buyers skipping test drive = 0.11

Buyers that use search engines AND skip test drives = 0.65 * 0.11 = 0.07

(a) To find this probability, we simply need to add the probabilities of the above conditions that meet the criteria of the question. Since all of the above conditions meet the criteria set by the question, we have:

Probability = 0.65 + 0.11

Probability = 0.76

(b) The probability of buyers that do not use search engines = 1 - 0.65 = 0.35

Probability of buyers that do not use search engines OR do skip the test drive = 0.35 + 0.11 = 0.46

(c) Probability of buyers buyers that do not skip test drive = 1 - 0.11 = 0.89

Probability of buyers using online search engine AND not skipping the test drive = 0.65 * 0.89 = 0.58

(It must be noted that question c is phrased wrong. Since both events are independent, i.e buying a car OR skipping the test drive would mean 0.65 + 0.89 = 1.54 (not possible) )
