Step-by-step explanation:

From the graph, it's a graph with a vertex hence its a quadratic equation without

When g(X)=2; x=0

F(4) =-10; from x=4 on the graph of f(x)

The required value of f(4) = -10, value of function evaluated from the graph.

A graph has been shown of f(x) and g(x).
g(x) = 2 is given and f(4) is to determine with the help of the graph.

The graph is a demonstration of curves  which gives the relationship between x and y axis.

The graph has been shown to find the value of f(x) coordinates located on the curve for every x on the number line of the x-axis.
In manner to locate f(4) draw the verticle from x = 4 the intersect at cover f(x)(yellow point). Now, draw the horizontal line from the yellow mark the line intersects at y = -10 on the y axis. i.e.
f(4) = -10

Thus, the required value of f(4) = -10, value of function evaluated from the graph.

Answer:

Hence, Stacy will spin 6,  8.33 times out of her n = 50 attempts.

Step-by-step explanation:

Let us consider a success to get a 6. In this case, note that the probability of having a 6 in one spin is 1/6. We can consider the number of 6's in 50 spins to be a binomial random variable. Then, let X to be the number of trials we get a 6 out of 50 trials. Then, we have the following model.

We will estimate the number of times that she spins a 6 as the expected value of this random variable.

Recall that if we have X as a binomial random variable of n trials with a probability of success of p, then it's expected value is np.

Then , in this case, with n=50 and p=1/6 we expect to have  number of times of having a 6, which is 8.33.

Answer:

Centimeters Mapped: 8.4 cm

Step-by-step explanation:

Let us plan out our steps, and solve for each:

1. If we want to determine the cm of the route on the map, let us first convert 2.1 kilometers ⇒ centimeters: 2.1 km = 210,000

2. Given such, let us create a proportionality as such:

          1        =           25,000      ⇒   x - route in cm mapped out

          x                   210,000

3. Now let us cross multiply, and solve through simple algebra:

210,000 = 25,000 * x,

x = 8.4 centimeters marked by a route on the map

Answer:

  (x -1)(x -5)

Step-by-step explanation:

We recognize that 6 is the sum of the factors of 1·5, so we can write the factorization as ...

  x^2 -6x +5 = (x -1)(x -5)

_____

The product of factors will be ...

  (x +a)(x +b) = x^2 +(a+b)x +ab

So, the binomial constants "a" and "b" are factors of the trinomial constant that have a sum equal to the coefficient of the linear term. Here, those are factors of +5 that have a sum of -6. The factors of interest are -1 and -5: 5 = (-1)(-5); -6 = (-1) +(-5).

From the given information,

The ten observation data on october  snow cover for Eurasia  during the years is 6.5, 12.0, 14.9, 10.0, 10.7, 7.9, 21.9, 12.5, 14.5, 9.2

What would you report as a representative, or typical, value of October snow cover for this period, and what prompted your choice?

For the given data, 21.9 is an outlier, so trimmed mean would be good choice for the researcher,

Remove the smallest and the largest values to compute the trimmed mean

[tex]\bar x = \frac{12.0+14.9+10.0+10.7+7.9+12.5+14.5+9.2}{8} \\\\=\frac{91.7}{8} \\\\=11.465[/tex]

Answer:

(x-5)(x-5) =3

X^2 -5x -5x +25 = 3

x^2 -10x +22 = 0

x1 = (-b + sqrt(b^2 - 4ac))/2a

x1= (10 + sqrt(4) x sqrt(3))/2

x1=(10 + 2 x sqrt(3))/2

x1 =5 +sqrt(3)

a number between 2 and 4 is 3

Answer:-2

Step-by-step explanation:

Log3(1/9)

Log(1/9) ➗ Log3

Log(1/3^2) ➗ Log3

Log3^(-2) ➗ Log3

-2Log3 ➗ Log3

-2(Log3 ➗ Log3)

-2

The solution of the expression by taking a log is, log₃ (1/9) = - 2

Used the formula for the logarithmic function,

log₃ (a)ⁿ = n log₃ (a)

log₃ (3) = 1

Given that,

The logarithmic function is,

log₃ (1/9)

It can be written as,

log₃ (3⁻²)

Since, log₃ (a)ⁿ = n log₃ (a)

So, we get;

- 2 log₃ (3)

- 2 × 1

- 2

Therefore, the solution is - 2.

Answer:

x = 12

∠A = 144

Step-by-step explanation:

+ We have: ∠A = ∠C (alternate interior)

                ∠D = ∠C ( vertically opposite angles)

=> ∠A = ∠C (because = ∠C)

=> 10x + 24 = 6x + 72

=> 10x - 6x = 72 - 24

Answer:

a) The number of claims decrease from 1990 to 1996.

b) The relative extrema is a minimum and happens approximately in 1996 (t=5.688). This means the moment when the number of claims stop decreasing and start to increase.

Step-by-step explanation:

The monthly average number of unemployment claims in a certain county is given by:

[tex]C(t)=24.31t^2-276.58t+2035[/tex]

With t: number of years after 1990.

We have to determine in what years the number of claims decrease and the relative extreme value.

We can find this by analizing the first derivative.

When the first derivative is equal to zero, this indicates an extreme value, which can be a maximum or minimum.

When the first derivative is positive, it indicates that the function is increasing. On the contrary, when the first derivative is negative, it indicates that the function is decreasing.

The first derivative is:

[tex]\dfrac{dC}{dt}=24.31(2t)-276.58(1)+0\\\\\\\dfrac{dC}{dt}=48.62t-276.58[/tex]

Then, we can calculate the extreme value:

[tex]\dfrac{dC}{dt}=48.62t-276.58=0\\\\\\48.62t=276.58\\\\\\t=\dfrac{276.58}{48.62}=5.688\approx 6[/tex]

This extreme value happens for t=6 (year 1996).

If we calculate the value of the first derivative for t=5, that is previous to the extreme value, we can find if the function was increasing or decreasing:

[tex]\dfrac{dC}{dt}(5)=48.62*5-276.58=243.10-276.58=-33.48<0[/tex]

As the value is  negative, we know that the number of claims was decreasing from t=0 to t=6 (from 1990 to 1996), and then reach a minimum and start to increase from them (from 1996 onwards).

Answer:

The calculated value Z = 1.8368 < 1.96 at 0.05 level of significance

The null hypothesis is accepted

The samples have been drawn from the same Population

Step-by-step explanation:

Step(i):-

Given first sample size 'n₁' = 49

Mean of the first sample 'x₁⁻ = 609.86

Standard deviation of the sample S₁ = 55.96 calories

Given first sample size 'n₂' = 78

Mean of the first sample 'x₂⁻ = 641.02

Standard deviation of the sample S₂ = 109.14 calories

Step(ii):-

Null hypothesis : H₀: x₁⁻ = x₂⁻

Alternative Hypothesis : H₁: x₁⁻ ≠ x₂⁻

Level of significance ∝ = 0.05

Test statistic

[tex]Z = \frac{x^{-} _{1}-x^{-} _{2} }{\sqrt{S.D^2(\frac{1}{n_{1} } }+\frac{1}{n_{2} } }[/tex]

where

 [tex]S.D^{2} = \frac{n_{1} S^2_{1}+ n_{2} S^2_{2} }{n_{1} + n_{2} -2}[/tex]

 [tex]= \frac{49 X (55.96)^2+ 78X(109.14)^2 }{49 + 78 }[/tex]

 σ² =  8660.357

Step(iii):-

Test statistic

[tex]Z = \frac{x^{-} _{1}-x^{-} _{2} }{\sqrt{S.D^2(\frac{1}{n_{1} } }+\frac{1}{n_{2} } }[/tex]

[tex]= \frac{ 609.86-641.02 }{\sqrt{8660.357(\frac{1}{49 } }+\frac{1}{78 } ) }[/tex]

[tex]Z = \frac{-31.16}{16.9638} = -1.8368[/tex]

|Z| = |-1.8368| = 1.8368

The slope of the equation is 1/33 and For every 33 feet a diver descends, the pressure increases by 1 atmosphere

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the first point be A

The value of A = A ( 0 , 1 )

Let the second point be = B

The value of B = B ( 100 , 4 )

Now , the slope of the points of the line is given by the equation

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 4 - 1 ) / ( 100 - 0 )

Slope m = 3 / 100

Slope m = 1/33

Therefore , the value of slope of the line is 1/33

And , when the diver swims a depth of 33 feet , the atmospheric pressure increases by 1

Hence , The slope of the equation is 1/33 and For every 33 feet a diver descends, the pressure increases by 1 atmosphere
