THIS IS TIMED AND I NEED HELP!!!
Which represents the solution(s) of the graphed system of equations, y = x2 + 2x – 3 and y = x – 1? (1, 0) and (0, –1) (–2, –3) and (1, 0) (0, –3) and (1, 0) (–3, –2) and (0, 1)

8 squared = 64

so

(x/4)*2 = 64

divide x/4 by 2 to get x/2=64

 now multiply both sides by 2 to get x=128

x = 128

The solution would be like this for this specific problem:

Given:

{0, 1, 2, 3, 4}
Success = 2, 3, and 4

Solution:

Success = 3 numbers
Sample = 5

= 3 / 5

= .6

= .6 * 100%

= 60%

So, the estimated probability of a success based from the randomly generated list of numbers being used to simulate an event is 60%.

To add, the measure of the likelihood that an event will occur is called probability and it is quantified as a number between 0 and 1, where, loosely speaking, 0 indicates impossibility and 1 indicates certainty.

Answer:

The option A.) 2007 is correct

Step-by-step explanation:

The formula which is to be used is given :

[tex]P(t) = 1.1\cdot e^{0.047t}[/tex]

where P(t) is the function of time t and t is the time in years after January 1 , 1980

Now, we need to find the year when the price will reach $4

So, substituting P(t) = 4 and finding the value of t from the given equation.

[tex]\implies 4=1.1\cdot e^{0.047t}\\\\\implies 3.64=e^{0.047t}\\\\\text{Taking natural log ln on both the sides}\\\\\implies \ln 3.64=\ln e^{0.047t}\\\\\implies 1.29=0.047\cdot t\\\\\implies t = 27.49[/tex]

So, t = 27.49 which is approximately equals to 27.5 years

So, 27.5 years after January 1, 1980 is the year 2007

Hence, The price will reach $4 in the year 2007

Therefore, The option A.) 2007 is correct

Final answer:

To find the z-score corresponding to a cumulative area of 0.8770 in a standard normal distribution, one can look up this area in a z-table or use statistical software, yielding a z-score of approximately 1.15.

Explanation:

The question involves finding the value of z in a standard normal distribution given that the cumulative area to the left of z is 0.8770.

The z-score is a measure that describes the position of a raw score in terms of its distance from the mean, measured in standard deviations.

To find the value of z corresponding to an area of 0.8770, one would typically use a z-table or statistical software. The z-table lists areas to the left (cumulative probabilities) for different z-values.

For an area of 0.8770, the z-score is approximately 1.15. This calculation is based on the standard normal distribution, where the mean is 0 and the standard deviation is 1.

Answer:

the value of x= 4.5

Step-by-step explanation:

If x varies directly with y and x = 3.5 when y = 14

x varies directly with y , so equation is x= ky

where k is the constant of proportionality

x = 3.5 when y = 14, use the given values and find out k

Plug in the given values in x=k y

3.5= k * 14

Divide by 14 on both sides

0.25= k

So the value of k = 0.25

Now find out x when y= 18

x= ky

x= 0.25 * 18= 4.5

divide 111 in half

111/2 = 55.5

 take the whole number above and below 55.5

 so you get 55 and 56

55 + 56 = 111

56 is the larger one

(B) Aiden should have found half the product of 1.1 and 5.4 because the 1.5 line is not perpendicular to 1.1 line.

Step-by-step explanation: Given that Aiden calculated the area of triangle QRS by finding half the product of 1.5 and 1.1.

We are to select the correct option which states the error made by Aiden.

The AREA of a triangle is given by

[tex]A=\dfrac{1}{2}\times \textup{base}\times \textup{altitude},[/tex]

where the altitude is perpendicular to the base.

In ΔQRS, the length of the base is given by

b = QS = 0.9 + 4.5 = 5.4 units

and

the length of the altitude is given by

h = 1.1 units.

So, the area of the triangle QRS will be

[tex]A=\dfrac{1}{2}\times b\times h=\dfrac{1}{2}\times 5.4\times 1.1[/tex]

Therefore, the area of ΔQRS will be calculated by finding half the product of 1.1 and 5.4.

So, Aiden made the error by finding half the product of 1.5 and 1.1, because 1.5 line is not perpendicular to 1.1 line.

Thus, Aiden should have found half the product of 1.1 and 5.4 because the 1.5 line is not perpendicular to 1.1 line.

Option (B) is correct.

Answer:

56

Step-by-step explanation:

The slope of the line passing through the points (12, -18) and (11, 12) is calculated using the formula for slope (y2 - y1) / (x2 - x1). The result is -30.

The subject of this question is Mathematics, more specifically the topic of 'Slope of a Line'. The grade level appears to be High School.

To answer the question 'Find the slope for the given coordinates (12,-18) and (11,12)', we use the formula to calculate the slope between two points which is (y2 - y1) / (x2 - x1). Let's take (12, -18) as (x1, y1) and (11, 12) as (x2, y2). Now we just input the values into the formula:

Slope (m) = (12 - (-18)) / (11 - 12).

This simplifies to Slope (m) = 30 / -1 = -30.

So, the slope of the line passing through the points (12, -18) and (11, 12) is -30.
