For a relation to be called a function, it must pas the vertical line test and each x-value must have a unique y-value

The graph of this sequence would pass the vertical line test.
Each day corresponds to a unique amount of pennies in this sequence.

⬆️ ⬆️ Question Please Help ☹

zysi [14]

Answer:

See the Venn diagram attached

Numbers given:

Total: 100
Either a cat of a fish: 70
Cat: 46
Cat and fish: 16

Neither a cat or a fish: 100 - 70 = 30

Fish: 70 - (46 + 16) = 70 - 62 = 8

Required probabilities are:

a) P(neither) = 30/100 = 0.3
b) P(f) = (16 + 8)/100 = 0.24
c) P(f not c) = 8/100 = 0.08

I NEED HELP PLEASE !!!!

Sergio [31]

Answer:

Step-by-step explanation:

2x + 3.5x + 15 = -1.5

5.5x + 15 = -1.5

5.5x = -16.5

x = -3

y = 3.5(-3) + 15

= -10.5 + 15

= 4.5

One sample has Aa Aa One sample has n 10 scores and a variance of s2 20, and a second sample has n 15 scores and a variance of s

siniylev [52]

Answer:

option (a) It will be closer to 30 than to 20

Step-by-step explanation:

Data provided in the question:

For sample 1:

n₁ = 10

variance, s₁² = 20

For sample 2:

n₂ = 15

variance, s₂² = 30

Now,

The pooled variance is calculated using the formula,

$S^{2}_{p} = \frac{(n_{1}-1)\times s^{2}_{1} +(n_{2}-1)\times s^{2}_{2}}{n_{1}+n_{2}-2}$

on substituting the given respective values, we get

$S^{2}_{p} = \frac{(10-1)\times 20 +(15-1)\times 30}{10+15-2}$

$S^{2}_{p}$ = 26.0869

Hence,

the pooled variance will be closer to 30 than to 20

Therefore,

The correct answer is option (a) It will be closer to 30 than to 20
