Answer: 1
Step-by-step explanation:
$5 because %15 of $70 is 10 and %5 of $10 is 5
Answer:
40.
Step-by-step explanation:
Let J represent jelly snake.
Let L represent lollipops
Let S represent sample space
Let y represent the number of jelly snake in the bag. I.e
Number of J = y
Number of L = 10
Number of S = 10 + y
From the question given, we were told that the probability of jelly snake P(J) is 4/5.
But probability of jelly snake, P(J) is given by:
P(J) = nJ/nS
nJ = y
nS = 10 + y
P(J) = 4/5
Thu, we can obtain the number jelly snake, y, in the bag as follow:
P(J) = nJ/nS
4/5 = y/(10 + y)
Cross multiply
5y = 4(10 + y)
Clear bracket
5y = 40 + 4y
Collect like terms
5y – 4y = 40
y = 40
Therefore, the number of jelly snake in the bag is 40
Answer:
D In step 3
Step-by-step explanation:
Given polynomial: x² - 2x - 15 = 0
Step 1: factor the polynomial ⇒ (x + 3)(x - 5) = 0
Step 2: x + 3 = 0 and x - 5 = 0
Step 3: x = -3 and x = 5
x - 5 = 0
Add 5 to both sides:
⇒ x - 5 + 5 = 0 + 5
⇒ x = 5
