nata0808 [166]
C = Cost To Download 
M = Membership Fee.
T = 0.99C + M

Now, Plug In 6 For C.
And 12.49 For M
T = 0.99 * 6 + 12.49

0.99*6 = 5.94

T = 5.94 + 12.49

5.94+12.49 = 18.43

T = 18.43.

So, If You Want To Buy 6 Games On The Website, It Will Cost $18.43

I need help can somewon help me?
Y_Kistochka [10]

Answer:

1. Lin raised $40

2. Jada raised $20

3. Andre raised $60

Step-by-step explanation:

1. It says Lin raised 100% of her goal and the goal was $40 which means that she earned $40

2. For this one it says Jada raised only 50% of her goal. To solve this one you just take half of 40 since it says she raised only 50% of her goal which gets you 20

3. For this one you just have to do some adding. The first part of the problem you take away the 50% of the 150% for a minute and that just leaves 100% which is a total of 40$ you then just look at the 50% by itself which is 20$. Then you take 40 and add the 20 to it which gets you a total of 60$

have a great day! :)

A certain group of women has a 0.86​% rate of​ red/green color blindness. If a woman is randomly​ selected, what is the probabil
Mariana [72]

Answer:

The probability that a randomly selected woman has red/green color blindness is 0.9914

Step-by-step explanation:

Given that the proportion of women having red/green color blindness is 0.86%

Represent that with p

p= 0.86\%

Convert proportion from percentage to decimal;

p= \frac{0.86}{100}

p= 0.0086

In probability; opposite probabilities add up to 1;

Let the probability that a woman selected have red/green color blindness be represented with q;

p + q = 1

Subtract p from both sides

p - p + q = 1 - p

q = 1 - p

Substitute 0.0086 for p

q = 1 - 0.0086

q = 0.9914

<em>Hence, the probability that a randomly selected woman has red/green color blindness is 0.9914</em>
