When a number is decreased by 45%, the result is 9. What is the original number to the nearest tenth?
Paul [167]

Answer:

16.4

Step-by-step explanation:

To decrease a number by 45% of its value, you subtract the 45%. To get 45%, you multiply the number by 0.45.

So, if x is the original number, then the equation for this word problem would be x - 0.45x = 9.

To solve, we first subtract 0.45x from x, which is 0.55x. This means that 0.55x is equal to 9. To simplify, we can divide both sides by 0.55. 9/0.55 is 16.36363636..., etc. The nearest tenth would be 0.4, so your answer is 16.4

Dana saved 450 for food for her upcoming vacation. The breakfast was included with their hotel, but lunch and dinner are not. Wh
zzz [600]

Answer:

10d + 40r \leq 450

Step-by-step explanation:

Given

Savings = 450

Dana\ Cooks, d = 10

Restaurant, r = 40

Required

Represent this as an inequality

When Dana cooks;

Cost\ per\ meal = 10

Cost\ per\ d\ meals = d * 10

Cost\ per\ d\ meals = 10d

At Restaurant

Cost\ per\ meal = 40

Cost\ per\ r\ meals = 40 * r

Cost\ per\ r\ meals = 40 r

Add these two results:

Result = 10d + 40r

<em>To represent as an inequality, the above result must be less than or equal to Dana's total savings</em>

i.e.

10d + 40r \leq 450

svetlana [45]

Answer:

0.013

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ (1−p)ⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

and p is the probability of success.

Given n = 6, p = 0.69, and r = 0 or 1:

P = ₆C₀ (0.69)⁰ (1−0.69)⁶⁻⁰ + ₆C₁ (0.69)¹ (1−0.69)⁶⁻¹

P = (1) (1) (0.31)⁶ + (6) (0.69) (0.31)⁵

P = 0.013
