Dafna1 [17]

2 + 3w < -1 < 3w + 5       |subtract 3w from all sides

2 < -1 - 3w < 5       |add 1 to all sides

3 < -3w < 6        |change the signs

-3 > 3w > -6      |divide both sides by 3

-1 > w > -2 → -2 < w < -1 → w ∈ (-2, -1)

Free_Kalibri [48]

Answer:

S_{25}=555

Step-by-step explanation:

Given that,

In an AP, the 6th term is 39 i.e.

a_6=a+5d\\\\39=a+5d\ ....(1)

In the same AP, the 19th term is 7.8 i.e.

a_{19}=a+18d\\\\7.8=a+18d\ ......(2)

Subtract equation (1) from (2).

7.8 - 39 = a+18d - (a+5d)

-31.2 = a +18d-a-5d

-31.2 = 13d

d = -2.4

Put the value of d in equation (!).

39 = a+5(-2.4)

39 = a- 12

a = 39+12

a = 51

The sum of n terms of an AP is given by :

S_n=\dfrac{n}{2}[2a+(n-1)d]

Put n = 25 and respected values,

S_{25}=\dfrac{25}{2}[2(51)+24(-2.4)]\\\\=555

Hence, the sum of first 25 terms of the AP is equal to 555.

A spinner is divided into 4 sections using the
andreev551 [17]

Answer:

0.88

Step-by-step explanation:

Given:

A spinner is divided into 4 sections using the  colours: red, orange, yellow, and green. After  50 trials, the spinner landed on red 10 times,  on orange 16 times, on yellow 6 times, and  on green 18 times.

To find: probability of the spinner not landing  on yellow

Solution:

Probability is the chance of occurrence of some event.

Total number of outcomes = 50

Number of favourable outcomes = 50 - 6 = 44

Probability of the spinner not landing  on yellow = Number of favourable outcomes / Total number of outcomes = \frac{44}{50}=\frac{22}{25}=0.88
