Answer:

The length of EF = x = 18 cm

Option A is correct.

Step-by-step explanation:

Ware given perimeter of triangle = 97 cm

We need to find length of EF = x = ?

The length of EG = x+7

The length of EF = x

The length of GF = 3x

The formula used is: [tex]Periemter \ of \ triangle= Sum \ of \ all \ sides \ of \ triangle[/tex]

Putting values and finding x i.e length of EF

[tex]Periemter \ of \ triangle= Sum \ of \ all \ sides \ of \ triangle\\97=x+7+x+3x\\97-7=5x\\5x=90\\x=\frac{90}{5}\\x=18 \ cm[/tex]

So, value of x=18 cm

The length of EF = x = 18 cm

Option A is correct.

Adults living in San Francisco, California

Step-by-step explanation:

The population is the large group from which the sample is selected or chosen. In the question given the sample is drawn from the adult population of  San Francisco who are aged 40 to  50 to find out whether they can buy

an electric vehicle sometime in the next year.

The population it can be generalized to is adults living in San Francisco, California.

A population is defined as the group of all the individual members or objects having some common interest or characteristics.

The individual members are called the sampling units or simply units.

Answer:

adults only who live in San Francisco

Answer:

The perimeter of the square LAMP is 8[tex]\sqrt{10}[/tex] units

Step-by-step explanation:

The rule of the distance between two points (x1, y1) and (x2, y2) is

d = [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex]

∵ LAMP is a square

∵ The sides of the square are equal in lengths

∴ LA = AM = MP = PL

Let us find the length of one side of it

∵ L = (-2, -3) and A = (4, -1)

∴ x1 = -2 and y1 = -3

∴ x2 = 4 and y2 = -1

→ Substitute them in the rule of the distance above to find LA

∵ LA = [tex]\sqrt{(4 - -2)^{2}+(-1--3)^{2}}[/tex]

∴ LA = [tex]\sqrt{(4+2)^{2}+(-1+3)^{2}}[/tex]

∴ LA = [tex]\sqrt{(6)^{2}+(2)^{2}}[/tex]

∴ LA = [tex]\sqrt{36+4}[/tex] = [tex]\sqrt{40}[/tex]

→ Simplify the root

∴ LA = 2[tex]\sqrt{10}[/tex] units

∵ The perimeter of the square = 4 × side

∴ The perimeter of the square = 4 × 2[tex]\sqrt{10}[/tex]

∴ The perimeter of the square = 8[tex]\sqrt{10}[/tex]

∴ The perimeter of the square LAMP is 8[tex]\sqrt{10}[/tex] units

Answer:

Interpreting the results:

a) At least 99.3% of the data lies between 12 standard deviations of the mean

b) The data lies between points 0 and 168

Step-by-step explanation:

The mean score on a driving exam for a group of driver's education students is 84 points, with a standard deviation of 5 points. Apply chebychev's theorem to the data using k= 12 interpret the results

Chebychev's theorem states that:

At least 1 - 1/k² data lies between k standard deviation of the mean

μ ± kσ

Where k is a positive number greater than 1

From the question above

μ = Mean = 84 points

σ = Standard deviation = 5 points

Hence: k = 12

We have:

1 - 1/12²

= 1 - 1/144

= 144 - 1/144

= 143/144

= 0.9930555556

Approximately = 99.3%

Interpreting these results means that At least 99.3% of the data lies between 12 standard deviations of the mean

Hence,

μ - kσ

84 - 12 × 7

= 84 - 84

= 0

μ + kσ

84 + 12 × 7

= 84 + 84

= 168

Hence, the data lies between points 0 and 168

Step-by-step explanation:

Answer:

y=4/5x-5

Step-by-step explanation:

to find the slope intercept form (y=mx+b) we must find the slope(m) first. We take the two points given and use the slope formula (y2-y1/x2-x1) take the point (0,-5) as (x1,y1) and the point (5,-1) as (x2,y2).Using the slope formula {-1-(-5)/5-0}. We get the slope equal to 4/5. Now we have y= 4/5x+b.To find b we must choose one point from the given and substitute x and y in the formula we have(y=4/5x+b). I chose (0,-5) so substituting that, (-5=4/5(0)+b), and to finally get b=-5.Now substitute b in the equation y=4/5x+b to get y=4/5x-5.

Answer:

x = 111 degrees

Step-by-step explanation:

the angle next to 164 degrees :

any line = 180 degrees, so 180 - 164 = 16 degrees

now you have two out of three angles in the triangle. All three angles of every triangle must add together to equal 180, so

180 = 53 + 16 + x

or

x= 180 - 53 - 16

x=111 degrees

Answer:

Step-by-step explanation:

diameter = 2r  

where r = 9.8

plugin value of r = 9.8 into the formula:

diameter = 2(9.8)

               = 19.6 units

The length of the diameter of the circle is option D 19.6 units.

Diameter is defined as the line from one point in the circle to the other point through the center of the circle.

WE know that the diameter = 2r  

where r = 9.8

Substitute value of r = 9.8 into the formula:

The diameter = 2(9.8)

The diameter = 19.6 units

Hence, the length of the diameter of the circle is option D 19.6 units.

#SPJ2

Answer:

Formula:(from trigonometry)

Tan(A+B)=(tanA+tanB)/(1-tanA*tanB)

Let A=22 degrees,B=23 degrees

Tan(22+23)=(tan22+tan23)/(1-tan22*tan23)

From trigonometry we know tan45=1

Therefore tan(45)=1=(tan22+tan23)/(1-tan22tan23)

=> 1-tan22tan23=tan22+tan23

=> tan22+tan23+tan23tan22 =1

Hence proved

No we can't travel faster than speed of light as it is the fastest

Chlorophyll is a pigment that absorbs light of particular wavelengths (mainly blue and red) .Chlorophyll in green plants spread out on stacks of membranes in chloroplasts.

Dark matter ia a material that we cannot see but we know that it exists because of it's effect on the objects and it is composed of particles that do not absorb,reflect or emit light.

Answer:

1. Dark matter is material that don't seen directly, it neither absorb anything, neither reflect and emit light.

2. No there is nothing which can travel faster than light.

3. In simple language, chlorophyll is those pigment which is present in all green plants and mainly responsible for the process of photosynthesis

Step-by-step explanation:

1.We can say there is dark matter but the only problem is we don't have any access to see it.

2.there is nothing faster than light because speed of light and time doesn't exist beyond any point.

Answer:

V = x³ - 3x² + 3x - 1

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( s is the measure of the side )

Here s = x - 1 , thus

V = (x - 1)³

   = (x - 1)(x - 1)(x - 1) ← expand the second pair using FOIL

   = (x - 1)(x² - 2x + 1) ← distribute

   = x³ - 2x² + x - x² + 2x - 1 ← collect like terms

   = x³ - 3x² + 3x - 1
