Solve for X .... -3(x-5)>18

Mathematics
1 answer:
Ilya [14]4 years ago
6 0

Answer:

x<-1

Step-by-step explanation:

We multiply by -1 of both sides and change the sense of inequality:

(-1)*(-3(x-5))>(-1)*18

3(x-5)<-18

3 passes by dividing

x-5<-18/3

x-5<-6

5 goes by adding:

x<-6+5

x<-1

Simon drove for 2 1/2 hours to get from his house to the beach. Simon averaged 55 miles per hour on the trip. What is the distan
Sav [38]

Answer:

The distance from Simon's house to the beach is 137.5 miles

Step-by-step explanation:

we know that

The speed is equal to the ratio of the distance and the time

Let

s ----> the speed in mph

x ----> the distance in miles

y ---> the time in hours

s=\frac{x}{y}

we have

s=55\ mi/h

y=2\frac{1}{2}\ h=\frac{2*2+1}{2}=\frac{5}{2}\ h

substitute in the formula and solve for x

55=\frac{x}{(5/2)}

x=(5/2)55\\x=137.5\ mi

If an object is shot with an initial velocity of 160 ft/sec, what is the smallest initial angle will you need to obtain a horizo
MrRissso [65]
To solve the question we shall use the formula for the range given by:
Horizontal range, R=[v²sin 2θ]/g
plugging in our values we get:
500=[160²×sin 2θ]/10
5000=160²×sin 2θ
0.1953=sin 2θ
thus:
arcsin 0.1953=2θ
11.263=2θ
hence:
θ=5.6315°~5.63

The probability that a radish seed will germinate is 0.7. A gardener plants seeds in batches of
Harlamova29_29 [7]

The standard deviation for the number of seeds germinating in each batch is 1.3

<u>Solution:</u>

<em><u>In binomial distribution, standard deviation is given as:</u></em>

\sigma=\sqrt{np(1-p)}

Where "n" is the number of observations

"p" is probability of getting success

We are given that:

Total batches of seed = 8

Probability that a radish seed will germinate is 0.7

Here success is getting radish seed germinated

<em><u>Then, the standard deviation for the number of seeds germinating in each batch.</u></em>

Plugging in values in formula, we get

\sigma=\sqrt{(8)(0.7)(1-0.7)}\\\\=\sqrt{(8)(0.7)(0.3)}\\\\=\sqrt{1.68}\\\\=1.29614\approx1.3

Therefore the standard deviation for the number of seeds germinating in each batch is 1.3
