The amount of money that Jace would have to pay in total if he goes on 5 rides is; $40

The amount of money that Jace would have to pay in total if he goes on r rides is; 5r + 15

The general form of the equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Now, Since the price of admission into the park is $15, it means that it is the y-intercept. Thus, c = $15

He pays $5 for every ride and as such this will be the slope. Thus;

Total cost = 5x + 15

where x is number of rides

For 5 rides;

Y(5) = 5(5) + 15

= $40

For r rides, the total cost is;

y(r) = 5r + 15

False. The weight of a variable in a standardized predictor environment does not necessarily indicate that the variable has a higher discriminating power.

Discriminating power is determined by the correlation of a predictor variable with the outcome variable. We can calculate the correlation between a predictor variable and an outcome variable using Pearson's correlation coefficient, which is represented by the formula:

r = (NΣXY - (ΣX)(ΣY)) / √[(NΣX2 - (ΣX)2)(NΣY2 - (ΣY)2)].

In this formula, N is the sample size, ΣX is the sum of the predictor variable, ΣY is the sum of the outcome variable, ΣXY is the sum of the products of the predictor and outcome variables, and ΣX2 and ΣY2 are the sums of the squares of the predictor and outcome variables, respectively. The Pearson's correlation coefficient ranges from -1 to +1, with +1 indicating perfect positive correlation, 0 indicating no correlation, and -1 indicating perfect negative correlation. A higher correlation coefficient indicates a higher discriminating power.

Therefore, the weight of a variable in a standardized predictor environment does not indicate whether or not the variable has a higher discriminating power; this is determined by the correlation between the predictor and outcome variables.

Answer:

Below

Step-by-step explanation:

Perimeter A = 2 (x+2 +x) = 4x + 4

Perimeter B = 2 ( 4x+2x) = 12x

now,equate them

4x+4 = 12x    solve for x   ....subtract 4x from both sides

4 = 8x

x = 1/2

The function is y = 3800 * (2.63)^x

There are 1257529 bacteria after 6 hours.

A. Let y be the number of bacteria after x hours.

We know that y=10,000 when x=1 and

y=3,800 when x=0.

So we can write the equation as follows:

y = 3800 * (10,000/3,800)^x

Evaluate

y = 3800 * (2.63)^x

B. To find the number of bacteria after 6 hours, we substitute x=6 into the equation above:

y = 3800 * (2.63)^6

Evaluate

y = 1257529

So, there are 1257529 bacteria after 6 hours.

The temperature at which the rate constant becomes five times greater than the rate constant at 275 K is 325 K.

Let's say that temperature is represented by t and the rate constant is represented by r.

Let' say r₁ = R, r₂ = 3R, t₁ = 275 K and t₂ = 300 K.

considering the relationship between rate constant and temperature is linear.

t - 300 = [(300 - 275)/(3R - R)](r -  3R)

t - 300 = (25/2R)(r - 3R)

We are asked to determine the temperature at which the rate constant becomes five times greater than the rate constant at 275 K.

t - 300 = (25/2R)(5R - 3R)

t - 300 = (25/2R)(2R)

t - 300 = 25

t = 325 K

Hence, the temperature at which the rate constant becomes five times greater than the rate constant at 275 K is 325 K.

True, the general form of a large-sample 100% confidence interval for a population proportion p is where is the sample proportion of observations with the characteristic of interest.

The general form of a large-sample 100% confidence interval for a population proportion p is given by the formula:

p ± z(standard error of p)

where p is the sample proportion of observations with the characteristic of interest and z is the critical value from a standard normal distribution corresponding to the desired level of confidence (e.g. z = 1.96 for a 95% confidence interval). The standard error of p is calculated as the square root of (p(1-p)/n), where n is the sample size.

This formula is based on the central limit theorem and the assumption that the sample is random and large enough (n > 30). In this case, the distribution of p is approximately normal and the confidence interval provides a range of plausible values for the true population proportion.

the probability that a student scored greater than 65 is 0.2389.

The probability that a student scored greater than 65 can be calculated using the standard normal distribution and the z-score. The z-score represents the number of standard deviations a value is from the mean, and can be calculated as follows:

z = (x - mean) / standard deviation

Where x is the score of interest (65)

Mean is the average score of the students (70)

Standard deviation is the standard deviation of the scores (7).

Plugging in the values, we get

z = (65 - 70) / 7 = -0.714.

Using a standard normal distribution table, we can find the probability that a student scored greater than 65 by finding the area to the right of the z-score. The probability of a student scoring greater than 65 is approximately 0.2389, or 23.89%.

Answer:

To find the lowest common multiple (LCM) of 1080, 1188, and 1815, we need to find the smallest number that is a multiple of all three numbers.

One way to find the LCM is to use prime factorization. We can prime factorize each number and then multiply the highest exponent of each prime factor to get the LCM.

1080 = 2^4 * 3^3

1188 = 2^2 * 3 * 199

1815 = 5 * 11 * 163

The LCM is:

2^4 * 3^3 * 5 * 11 * 163 = 1080 * 11 * 163

So the LCM of 1080, 1188, 1815 is 207940.

The ratio of blue marbles to the total number of marbles is; 3:16.

The total number of marbles in the jar is 18 red + 12 blue + 20 yellow + 14 green = 64.

So, the ratio of blue marbles to the total number of marbles can be expressed as 12:64.

This ratio can be simplified by dividing both the numerator and denominator by the greatest common factor, which in this case is 4.

So, the simplified ratio becomes 12/4 : 64/4 = 3:16.

This means for every 16 marbles in the jar, 3 of them are blue.

The simplified ratio of 3:16 can be understood as a fraction, where the numerator represents the number of blue marbles and the denominator represents the total number of marbles in the jar.

This fraction can be converted to a percentage by multiplying it with 100, which gives 18.75%.

Therefore, the ratio of blue marbles to the total number of marbles is 12:64, which simplifies to 3:16.

The reason that best supports Statement 4 in the

given proof is option A. Addition Property of Equality

The statement 4, "4x + 18 = 78," is an equation that is being derived from the previous statements in the proof. The left side of the equation (4x + 18) represents the value of m/X, which was given as 4x + 18 in statement 2.

The right side of the equation (78) represents the value of m2Y, which was given as 78° in statement 3.

Therefore, statement 4 is derived by substituting the known values of m/X and m2Y into the equation m/X = m2Y, which was given as statement 1.

The reason for this substitution is the Addition Property of Equality, which states that if you add the same value to both sides of an equation, the two sides remain equal.

In this case, the same value (4x + 18) is being added to both sides of the equation m/X = m2Y, resulting in the equation 4x + 18 = 78.

Answer: Maybe B

Step-by-step explanation:

Guess from heart.

The area under the curve between z = −2.0 and z = −1.0 is 0.1359.

We can use tables to find the area under the normal curve between two values of z.

However, tables give areas from z = 0 to z = 3.9 (beyond which there is literally no change). But as the normal curve is symmetric at z = 0, we can use it to find between any two given z values.

For example, for the area under the curve between z = −2.0 and z = −1.0, we can take values for z = 2.0 and z = 1.0; their difference will give the area between z = −2.0 and z = −1.0.

From tables for z = 1.0, we have 0.8413 and for z = 2.0, we have 0.9772 and

Hence, the Area under the curve between z = −2.0 and z = −1.0 is 0.9772−0.8413 = 0.1359.
