i=-9
Answer:
The probability is 0.026 to 3 d.p
Step-by-step explanation:
To calculate this , we shall be using the Bernoulli approximation.
let P = percentage of voters supporting the increase = 41% = 41/100 = 0.41
q = percentage of voters not supporting = 100-41% = 59% = 59/100 = 0.59
Now we want to calculate that exactly 15 out of 25 will vote in favor
Mathematically that would be ;
25C15 p^15 q^10
= 25C15 0.41^15 0.59^10
= 0.025981307443 or simply 0.026 to 3 decimal places
Answer:
y = 5
Step-by-step explanation:
Subtract 2y from either side. It'll cancel out both of them. Then the equation is 8y = 40.
Divide both sides by 8 and you get y=5
Pretty sure that's right. I have a dad who has a math degree so I think it would be right because he helps me every time.
After the discount, Sara received a change of <u>$3.54</u>.
Define discount.
The discount is <u>determined by dividing the purchase price by the item's par value</u>. Discount is the type of original price reduction or a new lower price for a product. In other words, a discount i<u>s a sum of money or a portion of the regular selling price of anything</u>.
Given that a discount is the price reduction of goods or services that store owners give at the advertised price, it can be computed using the formula <u>Discount = List Price - Selling Price.</u>
Solution Explained:
Given,
Price of apples = $11.88, price of berries = $7.58
The discount on the coupon is $3 and she paid with a $20 bill
So, total cost = 11.88 + 7.58 = 19.46
Applying discount on the cost = 19.46 - 3 = 16.46
The total change Sara gets is = 20 - 16.46 = $3.54
Therefore, Sara receives a change of $3.54
