M=-2 and containing with a slope p (7,3)

Mathematics

Step-by-step explanation:

I can't get your question ,but if you are asking for the equation of a line with the coordinates (7,3) and gradient m = -2

we use the expression

y-y1 =m (x-x1)

substitute the y1 and x1 coordinates and gradient in the formula

y -3 = -2 (x-7 )

y-2 = -2x +14

y=-2x+14+2

y=-2x+16

rearranging

2x+y-16=0

therefore the equation of that line is

2x +y -16 =0

The diagram shows a 5 cm x 5 cm x 5 cm cube.
mylen [45]

Answer:

~8.66cm

Step-by-step explanation:

The length of a diagonal of a rectangular of sides a and b is

\sqrt{a^2+b^2}

in a cube, we can start by computing the diagonal of a rectangular side/wall containing A and then the diagonal of the rectangle formed by that diagonal and the edge leading to A. If the cube has sides a, b and c, we infer that the length is:

\sqrt{\sqrt{a^2+b^2}^2 + c^2} = \sqrt{a^2+b^2+c^2}

Using this reasoning, we can prove that in a n-dimensional space, the length of the longest diagonal of a hypercube of edge lengths a_1, a_2, a_3, \ldots, a_n is

\sqrt{a_1^2 + a_2^2 + a_3^2 + \ldots + a_n^2}

So the solution here is

\sqrt{(5cm)^2 + (5cm)^2 + (5cm)^2} = \sqrt{75cm^2} = 5\sqrt{3cm^2} \approx 5\cdot 1.732cm = 8.66cm

Among 46​- to 51​-year-olds, 28​% say they have called a talk show while under the influence of peer pressurepeer pressure. Supp
sasho [114]

Answer:

0.8997, 0.9999

Step-by-step explanation:

Given that among 46​- to 51​-year-olds, 28​% say they have called a talk show while under the influence of peer pressure.

i.e. X no of people who say they have called a talk show while under the influence of peer pressure is binomial with p = 0.28

Each person is independent of the other and there are only two outcomes

n =7

a) the probability that at least one has not called a talk showcalled a talk show while under the influence of peer pressure

=P(Y\geq 1) where Y is binomial with p = 0.72

= 1-(1-0.72)^7\\=0.9999

b) the probability that at least one has  called a talk showcalled a talk show while under the influence of peer pressurepeer pressurethe probability that at least one has not called a talk showcalled a talk show while under the influence of peer pressure

=P(x\geq 1) =1-P(0)\\= 1-(1-0.28)^7\\=0.8997

1. In a game, if you roll a 6 on a 6-sided number cube, you lose a turn.
just olya [345]
Short answer = 20
Argument
Your chances of throwing a 6 = 1/6

Expected Throws = P(6) * Total Throws
Expected Throws = 1/6 * 120
Expected Throws = 20

Answer = 20 <<<<<

What is 1,345 /99 rounded to the nearest integer?
mylen [45]
It's 14 because when you divide you get 13 with a remainder of 58 which is over half of 99 which means that you round up to 14
