Answer:

x = 15 or x = -17

Step-by-step explanation:

It is given that,

(x + 1)² = 16

<u>To solve the quadratic equation</u>

The give equation is

(x + 1)² = 16    ----(1)

From equation (1) we can see that it is a quadratic equation

So we can take square root fro both sides we get

√[(x + 1)²] =√16

x + 1 = ±16

x + 1 = 16   or x + 1 = -16

x = 16 - 1 = 15   or x = -16 - 1 = -17

Therefore x = 15 or x = -17

If the probability of a student spending time reading is 0.10, the probability of spending time watching TV is 0.90 and the prob
joja [24]

Answer:

The probability is 0.97

Step-by-step explanation:

In this question, we are concerned with calculating the probability of a student spending time reading or watching TV.

To calculate this, we simply use a direct mathematical formula.

P( of spending time reading or watching tv) = P(of spending time reading) + P(spending time watching Tv) - P( of spending time watching Tv and reading)

From the question, we identify the probabilities as follows;

P(spending time reading) = 0.1

P(of spending time watching Tv) = 0.9

P(of spending time watching Tv and reading) = 0.03

Now, plugging these values, we have

P( of spending time reading or watching Tv) = 0.9 + 0.1 -0.03

= 1-0.03 = 0.97

Masja [62]

Answer:

C

Step-by-step explanation:

In option c, the first block is divided into 3 pieces where 2 parts are shaded whereas the second block is divided into 6 pieces where 3 parts are shaded

For both to be equivalent, both of them should be the same

2/3 = x/6

x = 4

4 pieces should be shaded in in the second block to be equal to the first one, in the diagram only 3 parts are shaded thus the answer is c
