Step-by-step explanation:
Slope is:
[tex]\frac{Change of y}{Change of x}[/tex]
Since there is no change of the y value, there is no slope.
help me im so sad determine the values of X for which f(x) is defined
Answer:
[tex]f(x) = \frac{(2x - 1)(3x - 2)}{9x - 4} \\ open \: brackets \\ = \frac{(6 {x}^{2} - 4x - 3x + 2) }{9x - 4} \\ = \frac{6 {x}^{2} - 7x + 2 }{9x - 4} \\ let \: x \: be \: 1 \\ f(1) = \frac{(6 - 7 + 2)}{(9 - 4)} \\ = \frac{1}{5} [/tex]

The mean and standard deviation of the sample data collected on continuous variable are -0.25 and 0.03, respectively. The following table shows the
relative frequencies of the data in the given intervals.
Interval
Relative Frequency

-0.25 < 3 < -0.22
-0.22 <3 < -0.19
-0.19 <<< -0.16
0.36
0.11
0.03
Based on the table, do the data support the use of a normal model to approximate population characteristics?
A Yes, because the sum of the relative frequencies is 1.00.
B
Yes, because the distribution of relative frequencies is very close to the empirical rule for normal models.
с
No, because the values are negative and normal models are used for positive values.
D
No, because the distribution of relative frequencies is very far from the empirical rule for normal models.
E
No, because the sample size and the population parameters are not known.
Answer:
B
Step-by-step explanation:
I know because I know that how
The correct answer is D. No, because the distribution of relative frequencies is very far from the empirical rule for normal models.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
To determine if the data supports the use of a normal model to approximate population characteristics, we need to examine the relative frequencies and see if they exhibit a bell-shaped or normal distribution.
Looking at the table, we see that the relative frequencies are not symmetrical and do not follow the empirical rule for normal models.
The largest relative frequency is in the interval from -0.28 to -0.25, and the frequencies decrease as we move away from this interval. Additionally, there are negative values in the data, which is not a characteristic of normal models.
Therefore, the correct answer is D. No, because the distribution of relative frequencies is very far from the empirical rule for normal models.

What is the value of (-15/8 + 1.5) divided by (15 - 14 3/4) Please help :( this is worth my whole year grade
Answer:
-3/2 which is a
Step-by-step explanation: finding the exact value
The value (-15/8 + 1.5) ÷ (15 - [tex]14\frac{3}{4}[/tex]) = -3/2,
Hence, Option A is correct.
The given expression is,
(-15/8 + 1.5) ÷ (15 - [tex]14\frac{3}{4}[/tex])
Since we know,
Dividing two fractions is equivalent to multiplying the first fraction by its reciprocal. The first step in splitting fractions is to get the reciprocal of the second fraction (reverse the numerator and denominator). Then, multiply the numerators.
Here we have to find the value of the given expression is,
We can write it as,
⇒ (-15/8 + 1.5) ÷ (15 - 59/4)
⇒ (-15 + 12)/8 ÷ (60-59)/4
⇒ -3/8 ÷ 1/4
⇒ -3/8 x 4/1
⇒ -3/2
Hence,
(-15/8 + 1.5) ÷ (15 - [tex]14\frac{3}{4}[/tex]) = -3/2

Answer:
w = 10
Step-by-step explanation:
3w = 30
Divide each side by 3
3w/3 = 30/3
w = 10
Answer: Correct answer is c.10
Step-by-step explanation:
3w = 30 (It means you divide)
/3 /3 (You would divide both sides by 3)

The formula 2 equals 18+ B plus he gives the perimeter P of a triangle decide links a B in C a triangular feel has issac measure 45 yards 29 yard and 34 yards with the perimeter of the field the perimeter of the field is?
Answer:
P = 646 yards
Step-by-step explanation:
The sides of a triangular field measure 45 yards 29 yard and 34 yards.
The formula that is used to find the perimeter is given by :
P = 2A+18B+C
Put A = 45, B = 29 and C = 34 to find the perimeter of the field.
P = 2(45)+18(29)+34
= 90 + 522 + 34
= 646 yards
Hence, the perimeter of the field is 646 yards.
Find m∠2. pls help!!!
Explanation:
The green and red angles are alternate exterior angles. They alternate on either side of the transversal line. They are exterior because they are outside the parallel lines (think of the interior region as a river and the exterior regions as the shorelines).
Recall that alternate exterior angles are congruent when we have parallel lines. This is similar to how alternate interior angles are congruent due to parallel lines.
Since the angles shown are congruent, this must mean angle 2 is also 130 degrees.

answer for brainliest
Answer:
the last option is the right answer
Step-by-step explanation:
last week:
d = 18
d = 18h = 6
this week:
d = 2.5h
i. if she walked for 6 hours this week, h = 6
d = 2.5h
d = 2.5 × 6
d = 15
* this means she walked at slower pace this week as she can only cover 15 miles in 6 hours whereas she can cover 18 miles in 6 hours last week
ii. if she walked for 18 miles this week, d = 18
d = 2.5h
18 = 2.5h
h = 18/ 2.5
h = 7.2
* this means she walked at a slower pace this week as she needs 7.2 hours to cover 18 miles whereas she only need 6 hours last week
Stephanie ran three sprints during practice. Her first sprint was 175 yards, her second sprint was 150 yards, and her third sprint was 225 yards. What was the total distance that Stephanie sprinted?
Answer:
Stephanie sprinted 550 yards.
Step-by-step explanation:
Given that,
Stephanie ran three sprints during practice.
Her first sprint was 175 yards, her second sprint was 150 yards, and her third sprint was 225 yards.
We need to find the total distance that Stephanie sprinted. It is simply equal to the sum of all above sprints.
Distance = 175 yards + 150 yards + 225 yards
= 550 yards
Hence, Stephanie sprinted 550 yards.

what is the range of the function f(x) = 3/4 |x| - 3
Answer:
all real numbers greater than or equal to -3
Step-by-step explanation:
Range: output values of a function (y-values)
Given function:
[tex]f(x)=\dfrac{3}{4}|x|-3[/tex]
This is an absolute value function so |x| ≥ 0
Therefore, as |x| ≥ 0:
[tex]\implies \dfrac{3}{4}|x|\geq 0[/tex]
[tex]\implies \dfrac{3}{4}|x|-3\geq -3[/tex]
So the range of the given function is [-3, ∞):
all real numbers greater than or equal to -3
