Answer:

Rose bought cinnamon candy more of.

Step-by-step explanation:

Rose bought ginger candy = $\frac{7}{20}$ kilogram

= 0.35 Kilogram

She bought cinnamon candy = 0.4 kilogram

As we know 1 kilogram = 1000 grams

0.35 kilogram = 1000 × 0.35 = 350 grams ginger candy

0.4 kilograms = 1000 × 0.4 = 400 grams cinnamon candy

Therefore, She bought cinnamon candy more.

AVprozaik [17]

Answer:

0.249 is the required proportion.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 822

Number of people who preferred foreign cars over domestic, x = 205

We have to find the proportion of new car buyers who prefer foreign cars.

Formula:

$\hat{p} = \dfrac{x}{n}$

Putting values, we get,

$\hat{p} = \dfrac{205}{822}\\\\\hat{p} = 0.249$

Thus, 0.249 is the proportion of the new car buyers who preferred foreign over domestic cars..

Identify an equation in slope-intercept from for the line parallel to y=-3x + 7 that passes through (2, -4)

alexandr1967 [171]

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

The parallel lines have the same slope.

We have y = -3x + 7 → m = -3. Therefore y = -3x + b.

Put the coordinates of the point (2, -4) to the equation of a line:

$-4=-3(2)+b$

$-4=-6+b$ <em>add 6 to both sides</em>

$2=b\to b=2$

<h3>Answer: y = -3x + 2</h3>

Answer: -5/21.

Step-by-step explanation:

$\frac{2}{5}*[\frac{-3}{7} +(\frac{-1}{6})]=\frac{2}{5} *(-\frac{3}{7} -\frac{1}{6}) =\frac{2}{5}*(-\frac{3*6+1*7)}{7*6} )=\frac{2}{5}*(-\frac{18+7}{42})=\frac{2}{5}*(-\frac{25}{42})=-\frac{5}{21} .$

Khloe and Emma work at a furniture store. Khloe is paid $245 per week plus 9.5% of her total sales in dollars, xx, which can be

ale4655 [162]

Answer: Their weekly pay would be the same if xx equals $1,600

Step-by-step explanation: The first and most important step is to identify what the question requires, and that is, what is the value of the unknown in the equation of their weekly incomes that would make their pay to be the same? Their weekly pay as per individual is given as follows;

Khloe = 245 + 0.095x ———(1)

Emma = 285 + 0.07x ———(2)

Simply put, we need to find the value of x when equation (1) equals equation (2)

245 + 0.095x = 285 + 0.07x

Collect like terms and we now have

0.095x - 0.07x = 285 - 245

0.025x = 40

Divide both sides of the equation by 0.025

x = 1600

Therefore their weekly pay would be at the same level, if x equals $1600
