2x + y= -1
y=ax?
10. For the system of equations above, what must be
true about the value of a if the system has no
solutions?
Answer:
a = -2
Step-by-step explanation:
The graphs of the lines would have to be parallel. So they must have the same slope. 2x + y = -1 changed to slope-intercept form is y = -2x - 1. Therefore, the slope of that line is -2. y = ax is in slope-intercept form where the slope is a. So, a must equal -2.

Answer:
f(x) = 2x + 1
Step-by-step explanation:
You can plug in the value to each one and see if the function is true. The only one in which the function is true is f(x) = 2x + 1, so the answer is 2x + 1.

Slope or gradient = 0.1073
Intercept = 4.5365
X = independent or predictor variable (leg press)
Y = predicted variable (40 yard dash)
B)
X = 22
Y = 0.1073(22) + 4.5365
Y = 6.8971
Y = 6.9

Answer:
We conclude that:
csc (U) = 26 / 24
Step-by-step explanation:
Given
The angle ∠U The opposite of the angle ∠U = 24The hypotenuse = 26To determine
csc (U) = ?
Using the trigonometric ration
sin Ф = opposite / hypotenuse
substituting Ф = U, opposite = 24, hypotenuse = 26
sin (U) = 24/26
We know that: csc (U) = [1 ] / [sin(U)]
Therefore,
csc (U) = [1 ] / [sin(U)]
= 26 / 24
Therefore, we conclude that:
csc (U) = 26 / 24

What is 12.36 rounded to the nearest whole number
Answer:
12.
Step-by-step explanation:
This is how to round 12.36 to the nearest whole number. In other words, this is how to round 12.36 to the nearest integer.
12.36 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 12
Fractional Part: 36
Our goal is to round it so we only have an integer part using the following rules:
If the first digit in the fractional part of 12.36 is less than 5 then we simply remove the fractional part to get the answer.
If the first digit in the fractional part of 12.36 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer.
The first digit in the fractional part is 3 and 3 is less than 5. Therefore, we simply remove the fractional part to get 12.36 rounded to the nearest whole number as:

Maya painted 3/4 of her art project in the morning and 1/8 of her project in the evening which wich equation can my used to find how much of project she painted in all
Answer: The project is 7/8 painted.
Step-by-step explanation: Add 1/8 to 3/4 for the total.
Use the least common denominator, /8
3/4 is equivalent to 6/8.
6/8 + 1/8 = 7/8
Step-by-step explanation: To find how much of the wall Maya painted, we will add the two fractions. Let's do it step-by-step.
1. These fractions have unlike denominators, to make them alike, we have to find the LCD (Least Common Denominator).
3/4 = 6/8
1/8 = 1/8
Note: What you did to the bottom, you do to the top.
1a. I multiplied 2 by 3 and 4 to get 6/8.
1b. I multiplied 1 by 1 and 8 to get 1/8.
2. Since we have like denominators, we can add!
[tex]Solve:\frac{6}{8} +\frac{1}{8} = \frac{7}{8}[/tex]
Therefore, your answer is 7/8. The fraction don't need to be reduced to lowest terms.

What would the height need to be for this curve to be a density curve?
-1/6
1/6
1/5
1
Answer:
One-sixth or 1/6
Step-by-step explanation:
A probability density curve satisfies several rules: It never goes below the horizontal axis, i.e. it's never negative. ... The chance of the quantity falling between a and b is the area under the curve between the point a and b.
The height of density curve is 1/6. Therefore, option B is the correct answer.
What is density curve?In probability theory, a probability density function, or density of a continuous random variable, is a function whose value at any given sample in the sample space can be interpreted as providing a relative likelihood that the value of the random variable would be close to that sample.
A density curve is always on or above the horizontal axis. The area underneath a density curve is exactly 1. The area under a density curve and above any range of values is the relative frequency of all observations that fall in that range.
The curve will never dip below the x ≥ Height>0
Area under the curve=Area of a rectangle with length=height of curve width=6
=Height of curve × 6
Area under the curve = 1
⇒ Height of curve × 6=1
=1/6
The height of density curve is 1/6. Therefore, option B is the correct answer.

Proportionally means
2 fractions (ratios) are NOT equal
2 fractions (ratios) are equal
Answer:
2 fractions are equal
Step-by-step explanation:
We say that two quantities are proportional if one is always the same multiple of the other.
Say a recipe calls for 2 cups of flour to 3 eggs. That proportion, 2 cups flour : 3 eggs, will always stay the same, no matter how many serving we make. If we make 2 servings, we'd double to 4 cups and 6 eggs, but that wouldn't change the proportion. After all,

Marine biologists are concerned that pollution from a nearby factory has affected the health of local sea urchins. Which of the following is most likely to be the population of interest?
Choose the correct answer below
A 4 sea urchins with abnormal coloration
B. All of the sea urchins near the plant
C. All of the sea urchins in the entire ocean
D. 20 sea urchins gathered from tidal pools
Answer:
its C. all of the sea urchin in the entire ovean is the most likely to be the population of interest
The population of interest will most likely be option B. all of the sea urchins near the plant.
The term 'population of interest' refers to the group or number from which inference is made or done for research purposes. And from this group, the researcher will try to draw conclusions from his/her study.
A population of interest is generally taken for studies or statistical references.In the given scenario, the biologists found that the nearby factory is directly affecting the health of the local urchins.And in conducting the research, the population of sea urchins near the plant will be taken or regarded as the population of interest.For the marine biologists to determine the extent of the factory's effect on the sea urchins, they would consider or take the sea urchins near the factory population as the population of interest. Thus, the correct answer is option B.

To estimate the mean height of female high school juniors, you take a
random sample of 30 female students and get these results (in inches):
72,51, 67, 68, 61, 69, 58, 56, 60, 56
66, 61, 60, 59, 59, 54, 58, 53, 68, 63
57, 62, 63, 64, 56, 62, 58, 67, 57, 70
If the o is 5.3, based on past research, and you want to construct a 97%
confidence interval using (estimate) + (margin of error)= (estimate)
what's your point estimate of ?
A. 30
B. 5.4
C. 65
D. 61.17
Answer:
61.16667 ; (58.958, 63.375)
Step-by-step explanation:
Given the data :
72,51, 67, 68, 61, 69, 58, 56, 60, 56, 66, 61, 60, 59, 59, 54, 58, 53, 68, 63, 57, 62, 63, 64, 56, 62, 58, 67, 57, 70
Standard deviation, σ = 5.3
Sample size, n = 30
The point estimate of the population mean:
Mean, m = Σx/n
Σx = 1835 ; n = 30
m = 1835 / 30
m = 61.16667
Confidence interval :
m ± Tn-1,α/2 * σ/sqrt(n)
61.16667 ± T30-1,0.03/2 * 5.3/sqrt(30)
61.16667 ± T29,0.015 * (5.3/sqrt(30))
61.16667 ± 2.282175 * (0.9676431)
Lower bound = 61.16667 - 2.20833 = 58.95834
Upper bound = 61.16667 + 2.20833 = 63.375
(58.958, 63.375)
