This type or graph is used to show comparisons between values, with a bar representing each separate value. Categories or groups are commonly plotted on the horizontal axis (axis X) and a quantitative or numerical scale is plotted on the vertical axis (axis Y). Bar graphs are used to plot both continuous and discontinuous, or discrete, data.
advantages: show each data category in a frequency distribution, display relative numbers/proportions of multiple categories, summarize a large amount of data in a visual, easily intepretable form, make trends easier to highlight than tables do, estimates can be made quickly and accurately, permit visual guidance on accuracy and reasonableness of calculations, accessible to a wide audience
disadvantages: often require additional explanation, fail to expose key assumptions, causes, impacts and patterns, can be easily manipulated to give false impressions
Answer:
W = 9.33 grams
X = 4.67 grams
Step-by-step explanation:
Given;
Mass of Z to be made = 14 grams
Composition of Z
W:X:Y = 2:1:3
To make 6 grams of Y requires 4 grams of W and 2 grams of X
Composition of Y (for 6grams)
W:X = 4:2 = 2:1
Substituting the composition of Y to Z
Z = W:X:Y = 2:1:3
Z = W:X:W:X = 2:1:2:1
summing them up, we have;
Z = W:X = 4:2 = 2:1
Since the final mixing ratio for W and X are 2:1, to make 14 grams of Z, we need;
W = 2/3 × 14grams = 28/3 grams
W = 9.33 grams
X = 1/3 × 14grams = 14/3 grams
X = 4.67 grams
Answer:
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 8 months = 8/12 = 2/3 years
P = $3000
R = 9.3%
Therefore
I = (3000 × 9.3 × 2/3)/100
I = 18600/100
I = $186
The maturity value (in dollars) of this loan would be
3000 + 186 = $3186
Surface area is what it seems to be. All of the area of the solid's faces together. Like a cube, just find the areas of all of the squares that make the cube then add them together.
