Determine whether the equation is a linear equation. If so, write the equation in standard form.
omeli [17]

Step-by-step explanation:

The general form of a linear equation is given by :

y = mx +b

Where

m is the slope

b is the y-intercept

(a) y = 2x - 3

It is in the form of a linear equation.

Standard form, y =2x+(-3)

(b) The equation is 4x = 2y

or

2y = 4x

y = 2x + 0

It is in the form of a linear equation with slope of 2 and y-intercept of 0.

Write each decimal in expanded form- <br>a.0.493<br>b.1.222
lapo4ka [179]
0.493 = 0.000 + 0.400 + 0.090 + 0.003
It may be also written as: 0.493 = 0 + 0.4 + 0.09 + 0.003

1.222 = 1.000 + 0.200 + 0.020 + 0.002
It may be also written as: 1.222 = 1 + 0.2 + 0.02 + 0.002

In a genetics experiment on​ peas, one sample of offspring contained 450 green peas and 371 yellow peas. Based on those​ results
laiz [17]

Answer:

P(G) = 0.55

the probability of getting an offspring pea that is green. Is 0.55.

Is the result reasonably close to the value of three fourths that was​ expected?

No

Expected P(G)= three fourths = 3/4 = 0.75

Estimated P(G) = 0.55

Estimated P(G) is not reasonably close to 0.75

Step-by-step explanation:

Given;

Number of green peas offspring

G = 450

Number of yellow peas offspring

Y = 371

Total number of peas offspring

T = 450+371 = 821

the probability of getting an offspring pea that is green is;

P(G) = Number of green peas offspring/Total number of peas offspring

P(G) = G/T

Substituting the values;

P(G) = 450/821

P(G) = 0.548112058465

P(G) = 0.55

the probability of getting an offspring pea that is green. Is 0.55.

Is the result reasonably close to the value of three fourths that was​ expected?

No

Expected P(G)= three fourths = 3/4 = 0.75

Estimated P(G) = 0.55

Estimated P(G) is not reasonably close to 0.75
