Answer:

Step-by-step explanation:

5/8

Odds against event are 5:8

Means ration of not happening of work =

5/8

Sample space has 8+5=13 possibilities

Probability it being to work=

8/13

H(x)=2x3 – 3<br> Find h(2)

djverab [1.8K]

When it tells you to find h(2), that means you plug in 2 for x.
If 2x^3 (to the third power)
2(2)^3-3

1. PEMDAS, exponents first
2^3=8

2. multiply
8x2=16

3. subtract
16-3=13

Hope this helps!

Which of the following relations has a domain of {2, 3, 6}? Choose all that apply. {(3, 3), (2, 2), (3, 2), (6, 1)} {(3, 1), (6,

Ganezh [65]

All except (0,2), (5,6), (5,3), and (4,3). The domain is the x and the range is the y, so the x coordinate has to either be 2, 3, or 6.

Pleaseeeee help me i know y'all smart enough for this one‍♀️

SpyIntel [72]

Answer:

x=1

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

x+4−3x=3x+2−3x

−2x+4=2

Step 2: Subtract 4 from both sides.

−2x+4−4=2−4

−2x=−2

Step 3: Divide both sides by -2.

-2x/-2 = -2/-2

The number of mosquitoes in Anchorage, Alaska (in millions of mosquitoes) as a function of rainfall (in centimeters) is modeled

GarryVolchara [31]

Answer:

7 centimeters of rain will produce the maximum number of mosquitoes (49 millions of mosquitoes)

Step-by-step explanation:

we have the function

$m(x)=-x^2+14x$

where

m(x) is the number of mosquitoes in Anchorage, Alaska (in millions of mosquitoes)

x is the rainfall (in centimeters)

This is a vertical parabola open downward

The vertex represent a maximum

The x-coordinate of the vertex represent the centimeters of rain that will produce the maximum number of mosquitoes

Convert the quadratic equation into vertex form

$m(x)=-x^2+14x$

Factor -1

$m(x)=-(x^2-14x)$

Complete the square

$m(x)=-(x^2-14x+7^2)+7^2$

$m(x)=-(x^2-14x+49)+49$

Rewrite as perfect squares

$m(x)=-(x-7)^2+49$

The vertex is the point (7,49)

therefore

7 centimeters of rain will produce the maximum number of mosquitoes (49 millions of mosquitoes)
