Answer:

x = 54 cookies

Step-by-step explanation:

We can use ratios to solve this problem


1 1/3 cups chocolate chips    3 cups chocolate chips

------------------------------------  = --------------------------------------

24 cookies                                   x cookies


Using cross products

1 1/3 * x = 3 * 24

Let change 1 1/3 to an improper fraction

1 1/3 = (3*1+1)/3 = 4/3

4/3 x = 72

Multiply each side by 3/4 to isolate x

3/4 * 4/3x = 72*3/4

x = 54 cookies

What is one point on a graph for the equation y=-3x-1 and how do we substitute it?
alukav5142 [94]

use the slope intercept equation to find the slope and the y intercept

y = mx-b

m = slope

b = y intercept

m is the number before the x so -3 is the slope

 and -1 is the y intercept

 so a point on the graph would be the y intercept at (0,-1)

 There are 7 Democrats and 6 Republicans on a local city council. A planning committee of 6 for affordable housing needs to be
Brut [27]

Answer:

The probability is 0.383.

Step-by-step explanation:

There are 7 democrats and 6 republicans  

Number of ways in which 4 democrats and 2 republicans can be selected=\[{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}\]

Number of ways in which 5 democrats and 1 republican can be selected= \[{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}\]

Number of ways in which 6 democrats can be selected = \[{}^{7}{{C}_{6}}\]

So, favourable outcomes are \[{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}+{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}+{}^{7}{{C}_{6}}\]

Total possible outcomes =\[{}^{13}{{C}_{6}}\]

Now, probability=\[\frac{Favourable}{Possible}=\frac{{}^{7}{{C}_{4}}\times {}^{6}{{C}_{2}}+{}^{7}{{C}_{5}}\times {}^{6}{{C}_{1}}+{}^{7}{{C}_{6}}}{{}^{13}{{C}_{6}}}=0.383\]
