Answer:

The number is -30.

Step-by-step explanation:

Given statement,

→ two thirds of a number is negative 20.

The equation will be,

→ (2/3)x = -20

Now the value of x will be,

→ (2/3)x = -20

→ 2x = (-20) × 3

→ x = (-60)/2

→ [ x = -30 ]

Hence, the value of x is -30.

Answer:

[tex]-30[/tex]

Step-by-step explanation:

Set up the equation where [tex]x[/tex] is the unknown number:

[tex]\frac{2}{3}x = -20[/tex]

Divide both sides by [tex]\frac{2}{3}[/tex]:

[tex]x = -20 \div \frac{2}{3}[/tex]

Rewrite division by a fraction as multiplication by its reciprocal:

[tex]x = -\frac{20}{1} \times \frac{3}{2}[/tex]

Multiply:

[tex]x = -\frac{60}{2}[/tex]

Simplify:

[tex]x = -30[/tex]

The total distance covered by catherine is 10 miles as the problem says, " Catherine drives to school each day and lives 5 miles away. After school, she drives to Kroger , which is 2 additional miles away from her house. Then she heads home and studies for a test before having dinner".

Distance is defined as an object's total movement without regard for direction. Distance can be defined as how much ground an object has covered regardless of its starting or ending point. The magnitude or size of displacement between two positions is defined as distance. The distance between two points differs from the distance traveled between them. The total length of the path traveled between two points is referred to as the distance traveled. Travel distance is not a vector. Distance refers to "how much ground an object has covered" while moving, whereas displacement refers to how far an object is out of place. Displacement is a Vector quantity, whereas distance is a Scalar quantity.

Here,

The total distance from home to school=5 miles

She goes to kroger that is 2 miles from her home,

so, 5-2=3 miles

So she travels 3 miles back from school.

Then she goes 2 miles from kroger to home.

5+3+2=10 miles

According to the problem, Catherine's total distance traveled is 10 miles "Catherine lives 5 miles away and drives to school every day. She drives to Kroger after school, which is two miles away from her house. She then returns home to study for a test before eating dinner ".

Step-by-step explanation:

Hope this helps and sorry if I'm wrong

The first step in solving for a in the equation would be:

1.distribute -4 to a and -5, then:

2a-4a+20=10

Now the next steps in solving for a:

2.Add 2a and -4a :

-2a+20=10

3.Substract 20 to both sides

-2a+20-20=10-20

then:

-2a= -10

4.Finally, divide both sides by -2

then, a=5

Answer:

-5(7a+ 6)

Explanation:

Given the expression:

-35a - 30

-35a = -5 * 7 * a

-30 = -5 * 6

You can see from the factors that -5 is common to both

Hence -5 is the GCF

Factoring out -5 from the expression will give;

-5(7a+ 6)

This gives the correct factor

Step-by-step explanation:

2.

angle B is congruent to angle B'.

side BC is congruent to side B'C'.

3.

angle pairs 1 and 3, 2 and 3, 5 and 7 are supplementary (together they have 180°).

4.

please burn this into your brain for all times : the sum of all angles in a triangle is always (yes, always) 180°.

so,

angle J + 17 + 84 = 180

angle J = 180 - 17 - 84 = 79°

5.

and here we use it again.

isoceles means that the triangle has 2 equally long legs. that makes also both base angles equally large.

apex angle + 24 + 24 = 180

apex angle = 180 - 24 - 24 = 132°

The speed of the river is 7.5 kilometers per hour.

Let the speed of boat in still water = u = 14 km/h

Let the speed of river = v = x km/h

Upstream speed = u - v = 14 - x

Downstream speed = u + v = 14 +x

Distance paddled upstream = [tex]D_{1}[/tex] = 5 km

Distance paddled downstream = [tex]D_{2}[/tex] = 10 km

Time taken (upstream) = [tex]T_{1}[/tex] = [tex]\frac{D_{1} }{u-v}[/tex]

Time taken (downstream) = [tex]T_{2}[/tex] = [tex]\frac{D_{2} }{u+v}[/tex]

According to question,

        [tex]T_{1}[/tex] = [tex]T_{2}[/tex]

      [tex]\frac{D_{1} }{u-v}[/tex] = [tex]\frac{D_{2} }{u+v}[/tex]

     [tex]\frac{5}{14-x}[/tex] = [tex]\frac{10}{14+x}[/tex]

5(14 + x) = 10(14 - x)

   14 + x = 2(14 - x)

   14 + x = 28 - 2x

  x + 2x = 28 - 14

        3x = 14

          x = [tex]\frac{14}{3}[/tex]

          x = 7.5

Hence, Speed of river is 7.5 km/h.

In order to express the confidence interval in the form p ± E, first we have to determine the midpoint of the interval, like this:

The value of the error, E, can be calculated by taking the difference between p and the end of the interval, like this:

Then, we can express 0.555 < p < 0.999 in p + E notation as 0.777 ± 0.222

The confidence interval can be written as 0.777 ± 0.222.

The confidence interval 0.555 < p < 0.999 can be expressed in the form of p ± E.

To find the margin of error (E), we can subtract the lower limit (0.555) from the upper limit (0.999) and divide it by 2:

E = (0.999 - 0.555) / 2

E = 0.222

Therefore, the confidence interval 0.555 < p < 0.999 can be expressed as:

p ± E

where p is the point estimate and E is the margin of error. In this case, the point estimate would be the midpoint of the interval, which is the average of the lower and upper limits:

p = (0.555 + 0.999) / 2

p = 0.777

Hence, the confidence interval can be written as 0.777 ± 0.222.

Answer:

There are many different ways to portray your findings for an individual to view and understand. However, each have their pros and cons. When using a table, all of the specific numbers of your data can clearly be seen and compared with one another without having to analyze a picture. However, since there is no visual correlation that shows the growth and decline of your data, someone who best comprehends visually may not be able to understand your findings. It sis best to vary your sources of displaying information to make sure that it is all able to be understood by any viewer. When using a graph, you have a clear visual representation of the correlation of your variables in your experimentation. This allows the viewer to comprehend your data as a picture and see the change as the picture moves. However, it take further analysis and cross referencing to get specific quantitative data as you are required to read across and down the graph. And finally, when using equations you can show the direct way that the change was caused in your experiment. Each equation has a specific input and output. However, the drawback is the person viewing your data may have to solve the equations themselves to find out your data or simply be confused as equations don’t directly show data, but rather how to find it. It is important to have a varied combination of these things to allow for your data to be throughly understood by anyone viewing it. I hope this helps! :)
