For what values of c does the binomial 5-3c take on a value which is greater than 80?

1 answer:

7 0

Answer: c > -25

From the question you can get the equation:
5 - 3c > 80; subtract 5 from both side
-3c > 75; divide -3 from both side
c > -25
So numbers including: -24, -23, -22, -21…
are all numbers that could work

The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as L = 10 lo

Inessa [10]

Answer:

50 Db

Step-by-step explanation:

we know that

The loudness in decibels is given by the formula

$L = 10log(\frac{I}{I_0})$

where

I = sound intensity in watts per square meter (Watts/m^2)

I₀ = reference intensity, = 10^(-12) Watts/m^2

For I=10^(-7) Watts/m^2

substitute in the formula above and solve for L

$L = 10log(\frac{10^{-7} }{10^{-12}})$

$L = 10log(10^{5})$

$L = 10 (5)=50\ Db$

A card is drawn from a well-shuffled deck of 52 cards. find the probability that the card is a red card or a 10.

harina [27]

Total number of cards = 52

Find total number of red card or a 10:

Total number of cards that are red = 26

Total number of cards that are 10 but not red = 2

Total number of cards that are red card or 10 = 26 + 2 = 28

P(red card or a 10) = 28/52 = 7/13

Answer: 7/13
