Answer:

all of them are blue so 1

Step-by-step explanation:

Answer:

a = 0.3

b = 0.4

c = 40%

d = 15%

Step-by-step explanation:

There are a total of 10 tick marks. So we know that 1 tick mark = 10%

a has 3 tick marks so you can say it's 0.3

b has 4 tick marks so you can say it's 0.4

c also has 4 tick marks, but it's asking for the percentage, so you get 40%

d is 1 1/2 tick marks. It's also asking for percentage. You know 1 tick = 10% and 1/2 tick = 5* so d = 15%

Answer:

a. 88.70% of the variation in the cost is being explained by the resolution.

Step-by-step explanation:

Given :

Summation of (Yi - Ybar)2 = 147172

Summation of (Yhat - Ybar)2 = 130542

Summation of (Y - Yhat)2 = 16630

The Coefficient of determination (R²) :

Sum of Square regression (SSR) / sum of square TOTAL (SST). It gives the percentage of the dependent variable which can be explained by the regression line.

Cost is the dependent variable in this scenario.

SSR = Summation of (Yhat - Ybar)2 = 130542

SST = Summation of (Yi - Ybar)2 = 147172

Hence,

SSR / SST = 130542 / 147172

R² = 130542 / 147172

R² = 0.8870029 = (0.8870029 * 100%) = 88.7%

ΔABC ≅ ΔDEF

Answer:

See Explanation

Step-by-step explanation:

Solving (a):

First, we categorize each data (to get their frequencies):

PI PI PI PI PI PI PI PI PI ---> Frequency: 9

S S S S S S S S---> Frequency: 8

V V V V V V V V V V V V  V ---> Frequency: 13

PO PO PO---> Frequency: 3

B ---> Frequency: 1

C  C ---> Frequency: 2

Total = 36.

The frequency table is as follows:

[tex]\begin{array}{cc}{Pizza\ Topping} & {Frequency} & {Beacon\ or\ Ham} & {9} & {Seafood} & {8} \ \\ {Vegetable\ and Fruit} & {13} & {Poultry} & {3} & {Beef} & {1} & {Cheese} & {2}\ \end{array}[/tex]

Solving (b): The relative frequency and percentage.

Relative frequency is calculated by dividing each frequency by the total frequency.

So, we have:

[tex]{Beacon\ or\ Ham} = \frac{9}{36} =0.250[/tex]

[tex]Seafood = \frac{8}{36} =0.222[/tex]

[tex]Fruits\ and\ Vegetable = \frac{13}{36}=0.361[/tex]

[tex]Poultry = \frac{3}{36}=0.083[/tex]

[tex]Beef = \frac{1}{36}=0.028[/tex]

[tex]Cheese = \frac{2}{36}=0.056[/tex]

The percentage is calculated by multiplying the frequency by 100%.

So, we have:

[tex]Bacon\ or\ Ham = 0.250 * 100\% = 25.0\%[/tex]

[tex]Seafood = 0.222 * 100\% = 22.2\%[/tex]

[tex]Fruits\ and\ Vegetable= 0.361 * 100\% = 36.1\%[/tex]

[tex]Poultry = 0.083 * 100\% = 8.3\%[/tex]

[tex]Beef = 0.028 * 100\% = 2.8\%[/tex]

[tex]Cheese = 0.056 * 100\% = 5.6\%[/tex]

Solving (c): Percentage that mentioned vegetables and fruits, poultry, or cheese?.

This is calculated as:

[tex]\%Percent = Vegetable\ and\ fruits + Poultry + Cheese[/tex]

[tex]\%Percent = 36.1\% + 8.3\% + 5.6\%[/tex]

[tex]\%Percent = 50\%[/tex]

Answer:

t = c - bp

Step-by-step explanation:

Where : t = number of t shirts sold per month ,

p = price per t shirt

Equation of t shirts sold in terms of price per t shirt , ie t = f (p) , is -

t = c - bp

As per law of demand - other factors remaining constant, price & sale demand of a product are inversely related to each other.

In equation- Negative intercept of 'p' in defining 't' denotes this inverse relationship. c denotes the constant autonomous value in the equation. b denotes the slope of demand equation, which signifies demand change in response to price change.

Answer:

12

Step-by-step explanation:

1,000 milliliters in a liter. 3 liters, so divide 3,000 by 250, which will give you 12. she can water 12 plants.

Step-by-step explanation:

Lester can water 12 plants because there is 1000 milliliters in one liter so if we do 1000x3=3000÷250=12 plants being able to get watered
