Francisca is asked to solve the
following equation, Francisca's
work is shown below.
3.5 = ** - 1.5
3.5 = {* - 1,5
+1.5 + 1.5
5 = ***

Francisca was supposed to add the 1/3, instead of subtracting by 1/3
Francisca was supposed to multiply by 3/1, instead of subtracting by 1/3
Francisca was supposed to divide by 1/3, instead of subtracting by 1/3
Answers
Answer:
Francisca was supposed to divide by 1/3, instead of subtracting by 1/3.
Step-by-step explanation:
She was completing the equation correctly until she subtracted 1/3 instead of dividing both sides. It should have been 5 divided by 1/3 or 15/3 divided by 1/3.
I hope this helps!

Answers
Answer:
y = 4
Step-by-step explanation:
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
where c is the value of the y- coordinates the line passes through
The line passes through (7, 4 ) with y- coordinate 4, thus
y = 4 ← equation of line

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
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

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.
Answers
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.

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.

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

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.

Answers
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.

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

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
