Find the slope and y-intercept of the line in each graph.
PLEASE HELP ASAP

Answer:

1 +4

Step-by-step explanation:

-1+2= 1

-2-2=-4

1--4=1+4

Answer:

y+2=1/2(x+3)

Why?

Point slope form is written as (y-y1) = m(x-x1) with y1 being the value of y at a certain point, x1 being the value of x at a certain point, and m being slope. y1 and x1 are given to us by the point (-3, -2) letting us know that y1=-2 and x1=-3. The only thing left to find is slope. Parallel lines have the same slope. If the line we are trying to find is parallel to the one given in the question, we just need to find the slope of the equation given. That equation is given in slope-intercept form which is y = mx + b. m is still slope so we can see that the slope is 1/2. Now we can plug m, x1 and y1 into the point slope form equation to get y + 2 = 1/2(x + 3)

Using proportions, the number of pounds that will be needed for a single serving is: one and three seventh pounds.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of pounds for 3 people is given by:

\(3 \frac{3}{7} = 3 + \frac{3}{7} = \frac{24}{7}\)

Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:

\(\frac{24}{7} \times \frac{1}{3} = \frac{24}{21}\)

24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:

one and three seventh pounds.

False. The statement is not entirely accurate. While significantly different sample variances can impact the assumptions of a t-test, it does not necessarily mean that a t-test cannot be conducted.

In traditional t-tests, there is an assumption of equal variances between the compared groups or populations. This assumption is known as the assumption of homogeneity of variances. If the sample variances are significantly different, it violates this assumption.

However, there are alternative versions of the t-test that can be used when the variances are not equal, such as the Welch's t-test or the modified t-test. These tests do not assume equal variances and can be applied when the variances are significantly different.

Therefore, it is possible to conduct a t-test even when the sample variances are significantly different, using appropriate modifications to the test. However, it is essential to consider the validity and appropriateness of the chosen test based on the specific circumstances and assumptions of the data.

The provider order is a safe dose for this child.

We have,

To determine if the provider order is a safe dose for the child, we need to calculate the child's weight in kilograms and then check if the ordered dose falls within the recommended dose range.

Given:

Child's weight: 35 lbs

Step 1: Convert the child's weight from pounds to kilograms.

1 lb is approximately equal to 0.4536 kg.

35 lbs x 0.4536 kg/lb = 15.876 kg (rounded to three decimal places)

Step 2: Calculate the dose range based on the child's weight.

Minimum dose: 15 mg/kg x 15.876 kg = 238.14 mg (rounded to two decimal places)

Maximum dose: 25 mg/kg x 15.876 kg = 396.90 mg (rounded to two decimal places)

Step 3: Compare the ordered dose to the calculated dose range.

Ordered dose: 300 mg

The ordered dose of 300 mg is within the calculated dose range of 238.14 mg to 396.90 mg.

Therefore,

The provider order is a safe dose for this child.

Probability that none of them voted in the primary election: 0.45, Probability that only one of them voted in the primary election: 0.44, Probability that 2 of them voted in the primary election: 0.18, Probability that all three of them voted in the primary election: 0.04

To calculate these probabilities, we can use the binomial distribution formula:
P(X=k) = (n choose k) * p^k * (1-p)^(n-k)
where:
- n is the sample size (in this case, 3)
- k is the number of "successes" (in this case, voting in the primary election)
- p is the probability of success (in this case, 0.35)
Probability that none of them voted in the primary election:
P(X=0) = (3 choose 0) * 0.35^0 * (1-0.35)^(3-0) = 0.45
Probability that only one of them voted in the primary election:
P(X=1) = (3 choose 1) * 0.35^1 * (1-0.35)^(3-1) = 0.44
Probability that 2 of them voted in the primary election:
P(X=2) = (3 choose 2) * 0.35^2 * (1-0.35)^(3-2) = 0.18
Probability that all three of them voted in the primary election:
P(X=3) = (3 choose 3) * 0.35^3 * (1-0.35)^(3-3) = 0.04
So the probabilities are:
- Probability that none of them voted in the primary election: 0.45
- Probability that only one of them voted in the primary election: 0.44
- Probability that 2 of them voted in the primary election: 0.18
- Probability that all three of them voted in the primary election: 0.04

b) Solving the matrix equation, we find r = 8, l = 4, and i = 3. The florist can use 8 roses, 4 lilies, and 3 irises for each centerpiece.

a) The system of linear equations representing the situation is:

r + l + i = 15 (total flowers in one centerpiece)

r = 2(l + i) (twice as many roses as irises and lilies combined)

10(2.50r + 4l + 2i) = 370 (total budget)'

Matrix equation: AX = B, where

A = [[1, 1, 1], [2, -1, -1], [25, 40, 20]],

The Complete Question:

A florist is creating 10 centerpieces. Roses cost $2.50 each, lilies cost $4 each, and irises cost $2 each. The customer has a budget of $370 allocated for the centerpieces and wants each centerpiece to contain 15 flowers, with twice as many roses as the number of irises and lilies combined. (Let r represent the number of roses, l represent the number of lilies, and i represent the number of irises.)

a) Write a system of linear equations that represents the situation. Then write a matrix equation that corresponds to your system.

b) Find the number of flowers of each type that the florist can use to create the 10 centerpieces.

The  given equation x=\(y^{z}\), y=\(z^x}\) , z=\(x^{y}\)is: b . xyz=1.

To solve this system of equations we have to  substitute the given equations into one another:

First equation:

x = \(y^{z}\)

Substitute  into the second equation:

\((y^{z})^x\) = \(y^({zx})\)

Taking the logarithm of both sides:

log(y) = zx * log(y)

Simplify

1 = zx

Substitute the value of z into the third equation:

\(z = (x^y) = (y^z)^y = y^(^z^y).\)

Take the logarithm of both sides:

log(z) = zy * log(y)

Simplify

1 = zy

From the first equation x =\(y^z,\) 1 = zx and 1 = zy.

Multiply the equations

1 * 1 = zx * zy,

1 = \(z^2\) * xy,

xyz = 1

Therefore the correct option is b.

We can expect the mean length of ears in the next generation to be 31.6 cm.

It is given that the narrow sense heritability (h2) is 0.70, which means that 70% of the total variation in maize ear length is due to genetic factors.

Let the mean length of ears in the original population be µ and the mean length of ears in the selected plant be x. Then, we can use the formula for response to selection to find the expected mean length of ears in the next generation:

x' = µ + h2 * (x - µ)

Substituting the given values, we get:

x' = 28 + 0.70 * (34 - 28) = 31.6 cm

Therefore, we can expect the mean length of ears in the next generation to be 31.6 cm.

Answer: Another factor is 3x + 5.

Step-by-step explanation:

please view the attachment for the steps.

The other factor of the polynomial (6x² + x - 15) would be (3x + 5). Hence option 2 is true.

Given that the polynomial is,

6x² + x - 15

And, The polynomial has a factor of 2x - 3.

Now apply the factorization method to solve for the  factor,

6x² + x - 15

6x² + (10 - 9)x - 15

6x² + 10x - 9x - 15

2x (3x + 5) - 3 (3x + 5)

(2x - 3) (3x + 5)

Since The polynomial has a factor of 2x - 3.

Hence, the other factor would be (3x + 5). So option 2 is true.

The correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.

A correlation coefficient measures the strength and direction of the relationship between two variables. In this case, the correlation coefficient of 0.90 indicates a strong positive linear correlation between happiness and GPA of high school students.

A positive correlation means that as one variable (in this case, happiness) increases, the other variable (GPA) also tends to increase. The magnitude of the correlation coefficient, which ranges from -1 to 1, represents the strength of the relationship. A value of 0.90 indicates a very strong positive linear correlation, suggesting that there is a consistent and significant relationship between happiness and GPA.

This means that as the level of happiness increases among high school students, their GPA tends to be higher as well. The correlation coefficient of 0.90 suggests a high degree of predictability in the relationship between these two variables.

It is important to note that correlation does not imply causation. While a strong positive correlation indicates a relationship between happiness and GPA, it does not necessarily mean that one variable causes the other. Other factors or variables may also influence the relationship between happiness and GPA.
