Answer:
x= 7 y= 9 (7,9)
Step-by-step explanation:
solve by using system if equations. multiply top answer by 2, giving u 2y=2x+4 and y=2x-5 subtract the equations. y=9 (the x cancels out) then put 9 in for y. 9=x+2. subtract 2. giving u 7. and now x =7
What is the value of (-15/8 + 1.5) divided by (15 - 14 3/4) Please help :( this is worth my whole year grade
Answers
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

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.

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.

Please help :( I’ll give you brainiest ♡
Answers
Answer:
$1.75
Step-by-step explanation:
Set up a system of equations where x is the cost of a corndog and y is the cost of a coke:
3x + y = 7.1
2x + 2y = 7.2
Solve by elimination by multiplying the top equation by -2
-6x - 2y = -14.2
2x + 2y = 7.2
Add them together:
-4x = -7
x = 1.75
So, the cost of one corndog is $1.75

7. A city lot is twice as long as it is wide, If its perimeter is 480 units, what are the dimensions of the lot?
Answers
Answer:
Step-by-step explanation:
P = 480
P = 2 length + 2 width
but we also know that
2width = length
so plug that into the length
P = 2(2width) + 2 width
480 = 4 width + 2 width
480 = 6 width
80 = width
160= length

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?
Answers
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.

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?
Answers
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.

Assuming you require the equation of the line.
A line with a slope of zero is a horizontal line parallel to the x- axis, with equation
y = c

The line passes through (7, 4 ) with y- coordinate 4, thus
y = 4 ← equation of line

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.
