djyliett [7]3 years ago
7 0

Answer:

b=1

Step-by-step explanation:

3.2 = \frac{4}{5} (b - 5)\\3.2 = \frac{4}{5}b - \frac{4}{5} *5\\3.2 = \frac{4}{5}b - 4\\3.2 = -3\frac{1}{5}b\\3.2 = -3.2b\\1 = b\\b= 1

PLZ HELP I WILL MARK BRAINLYIST!!!!!!!Explain the difference between a dot plot and a histogram. When would you use each graph?
mixas84 [53]

Answer:

Histograms subdivide data into intervals (bins), and use rectangles (usually columns) to show the frequency (count) of observations in each interval. ... Dot plots include ALL values from the data set, with one dot for each occurrence of an observed value from the set.

Step-by-step explanation:

histogram-Analyzing whether a process can meet the customer's requirements. Analyzing what the output from a supplier's process looks like. Seeing whether a process change has occurred from one time period to another. Determining whether the outputs of two or more processes are different.

Dot plots are used for continuous, quantitative, univariate data. Data points may be labelled if there are few of them. Dot plots are one of the simplest statistical plots, and are suitable for small to moderate sized data sets. They are useful for highlighting clusters and gaps, as well as outliers.

write the equation of the line that passes through the given points expressed in slope-intercept form. m=2/3, (-4,5)
solniwko [45]

Answer:

y = \frac{2}{3}x + \frac{23}{3}

Step-by-step explanation:

To write the equation of a line with a point and a slope, use the point-slope form of a linear equation. Substitute m = 2/3 and the point (-4,5) into the equation.

y - y_1 = m(x-x_1)\\y - 5 = \frac{2}{3}(x --4)\\y - 5 = \frac{2}{3}(x+4)

Convert to slope intercept form by using the distributive property.

y - 5 = \frac{2}{3}(x+4)\\y - 5 = \frac{2}{3}x +\frac{8}{3}\\y = \frac{2}{3}x + \frac{8}{3} + 5\\y = \frac{2}{3}x + \frac{23}{3}

Solve for x: 3(x + 1) = −2(x − 1) − 4
Anika [276]
Solve your equation step-by-step.

3(x+1)=−2(x−1)−4


Simplify both sides of the equation.

3(x+1)=−2(x−1)−4

Simplify:

3x+3=−2x−2

Add 2x to both sides.

3x+3+2x=−2x−2+2x

5x+3=−2

Subtract 3 from both sides.

5x+3−3=−2−3

5x=−5

Divide both sides by 5.

5x/5 = −5/5

x=−1
