what is the sum of -4/7 and 6/7
Answer:
2/7
Step-by-step explanation:
Since the denominators are the same, we need to add the numerators and place it over the common denominator
-4+6 = 2
so
-4/7 + 6/7 = 2/7

Twice a year, the P.E. teachers test the fitness level of all sixth-grade students at Walker Middle School. The students' weights and heights are measured as well as the time it takes each student to run a mile and the number of sit-ups and push-ups each student can do.
Which of the following are statistical questions that can be answered by the data gathered in the first fitness test of the year?
How many chin-ups can a sixth-grade boy do?
What are the weights of the sixth-grade boys?
How many sixth-grade students are there?
How many push-ups can a sixth-grade girl do?
What is the shortest height of the sixth-grade students?
What are the heights of the eighth-grade girls?
Answer : b: How many push-ups can a sixth grade girl do? and d:What are the weights of the sixth grade boys?
Answer:
How much do sixth grade boys weigh?
How many push-ups can a sixth grade girl do?
Step-by-step explanation:
A statistical question is one that has a variable answer.
Determine which questions are statistical questions and can be answered with the data gathered in the fitness test.
The questions "How many sixth grade students are there?" and "What is the shortest height of the sixth grade students?" can be answered with the data gathered in the fitness test. However, they do not have variable answers, so they are not statistical questions.
The questions "What are the heights of the eighth grade girls?" and "How many chin-ups can a sixth grade boy do?" do have variable answers, so they are statistical questions. However, these questions cannot be answered with the data gathered in the fitness test.
The questions "How much do sixth grade boys weigh?" and "How many push-ups can a sixth grade girl do?" do have variable answers, so they are also statistical questions. These questions can be answered with the data gathered in the fitness test.

hey i need some help with a fraction this is the question 17*5/8
Answer:
Fraction: 10 and 5/8
Step-by-step explanation:
17 × 5/8
85/8
Answer:[tex]10\frac{5}{8}[/tex] or 10.625
Step-by-step explanation:
First of all, note that 17 is the same as 17/1 since 17 divided by 1 is 17. Therefore, start by setting up the problem like this:
[tex]\frac{17}{1} X \frac{5}{8}[/tex]
Multiply the numerators together (17 x 5 = 85) and multiply the denominators together (1 x 8 = 8) and make it into one fraction like so:
[tex]\frac{85}{8}[/tex]
Convert the improper fraction above to a mixed number to get the answer:
[tex]=10\frac{5}{8}[/tex]
Ok, 20 points for this one
Answer:
x = 7Step-by-step explanation:
2 angles are added to result in = 180°
therefore
180 = 97 - 3x + 69 + 5x
180 = 166 + 2x
2x = 180 - 166
2x = 14
x = 14 ÷ 2
x = 7 ✅The value of x = 7

Using factor theorem , show that (x -4) is a factor 2x3 + x2 -26x - 40 and hence factorize completely.
Step-by-step explanation:
if x-4 is a factor of 2x^3 + x^2- 26x - 40
then f(4) = 0
f(x) = 2x^3 + x^2- 26x - 40
f(4) = 2(4)^3 + (4)^2 - 26(4) - 40
f(4)= 2(64) + 16 - 104 - 40
f(4) = 128 + 16 - 104 - 40
f(4) = 0
hence factorize completely is the photo

If angle DCA measures 40 degrees, what does angle ACB measure?
*see attachement for the diagram that is being referred to
Answer:
m<ACB = 50°
Step-by-step explanation:
From the diagram, <DCB is a right angle = 90°
Therefore:
m<DCA + m<ACB = 90° (complementary angles)
m<DCA = 40° (given)
Thus:
40° + m<ACB = 90° (Substitution)
m<ACB = 90° - 40° (Subtraction property of equality)
m<ACB = 50°

In the ranger's function, time is the

please help !!
Answer:
its independent and changes by constant factor per year
In the ranger's function, time is the independent variable, and the total number of deer in the park is the dependent variable.
Given data:
A park ranger recorded the number of deer living in a state park for several years and developed the function p ( t ) = 80 ( 1.2 )^t to model the total number of deer in the park "t" years after she began recording the data.
The total number of deer in the park is represented by "p(t)," which is the output of the function. As the value of "t" increases, the function calculates the total number of deer in the park based on the initial value of 80 and the growth rate of 1.2.
Hence, the time is the independent variable and number of deer is the dependent variable.

- 50 + (5 / 13)p this says negative 50 plus 5/13 times p
if p = -26 what does this epression evaluate to?
- 50 + (5 / 13) × p p = -26 substitute the value of p into the expression
- 50 + (5 / 13) × (-26)
- 50 + (5 (-26) / 13) I just rewrote the expression to make it clearer
that the -26 in -26/1 and the 5 in 5 / 13 are
both in the numerator over denominator 13
- 50 + (5 (-26) / 13) -26 / 13 evaluates to -2
-50 + (5)(-2)
-50 + (-10)
-50 - 10

Given cos theta = - 2/5 and sin theta < 0, find the six trigonometric values. I need help with this
Answer:
[tex]\sin\,\theta =-\frac{\sqrt{21} }{5}[/tex]
[tex]\tan\,\theta =\frac{\sqrt{21} }{2}[/tex]
[tex]\sec\,\theta = \frac{-5}{2}[/tex]
[tex]cosec\,\theta =\frac{-5}{\sqrt{21} }[/tex]
[tex]\cot\,\theta =\frac{2}{\sqrt{21} }[/tex]
Step-by-step explanation:
[tex]\cos\theta =\frac{-2}{5}<0\\sin\theta <0[/tex]
As both [tex]sin\,\theta<0,\,\cos\,\theta <0[/tex],
[tex]\theta[/tex] lies in the third quadrant.
In the third quadrant,
[tex]\sin\theta<0,\,\cos\,\theta <0\,,\,\sec\,\theta<0,\,cosec\theta<0,\,tan\,\theta>0,\,cot\,\theta>0[/tex]
[tex]\sin\,\theta =-\sqrt{1-\cos^2\,\theta} \\=-\sqrt{1-(\frac{-2}{5})^2 } \\\\=-\sqrt{1-\frac{4}{25} }\\\\=-\sqrt{\frac{25-4}{25} }\\\\=-\frac{\sqrt{21} }{5}[/tex]
[tex]\tan\,\theta = \frac{\sin\,\theta}{\cos\,\theta }\\\\=\frac{\frac{-\sqrt{21} }{5} }{\frac{-2}{5} }\\\\=\frac{\sqrt{21} }{2}[/tex]
[tex]\sec\,\theta =\frac{1}{\cos\,\theta }\\\\=\frac{1}{\frac{-2}{5} }\\\\=\frac{-5}{2}[/tex]
[tex]\ cosec \,\theta = \frac{1}{sin\,\theta }\\\\=\frac{1}{\frac{-\sqrt{21} }{5} }\\\\=\frac{-5}{\sqrt{21} }[/tex]
