The current depth of the hole is at least 20 feet below ground level.

Inequality is an expression that shows the non equal comparison of numbers and variables.

Let d represent the current depth of the hole.

To be at least 40 feet below ground level, he need more than 2 times its current depth.

2d < -40

d < -20

Hence the current depth of the hole is at least 20 feet below ground level.

Answer:

The ratio is $\frac{19}{3}$

Step-by-step explanation:

The question in English is

In a group of high school third graders, 38 are right-handed and 6 are left-handed. find the ratio of right-handed to left-handed

Let

x -----> number of students that are right-handed

y -----> number of students that are left-handed

we know that

To find out the ratio of right-handed to left-handed, divide the number of students that are right-handed by the number of students that are left-handed

$\frac{x}{y}$

we have

$x=38\ right-handed\\y=6\ left-handed$

substitute

$\frac{38}{6}$

Simplify

$\frac{19}{3}$

A winning football team more than doubled. The offensive yards gained by its opponent. The opponent gained 272 offensive yards.

Daniel [21]

Answer:

$80x>2*272$

More than 6.8 yards per game.

Step-by-step explanation:

Let x be the possible number of yards per play for the winning team.

We have been given that the winning team had 80 offensive plays, so the number of possible yards in 80 offensive plays will be 80x.

We have been given that a winning football team more than doubled the offensive yards gained by its opponent.

We can represents this information in an inequality as:

$80x>2*272$

Therefore, the inequality $80x>2*272$ can be used to find the possible number of x of yards per play for the winning team.

Let us solve for x.

$80x>544$

Let us divide both sides of our inequality by 80.

$\frac{80x}{80}>\frac{544}{80}$

$x>6.8$

Therefore, the winning team will score more than 6.8 yards per play.

Fail to reject the Null

Step-by-step explanation:

Given :

μ = 21 minutes

x = 22.4 minutes

Sample size, n = 36

Standard deviation, s = 6

H0: μ ≥ 21

H1: μ < 21

Test statistic : (x - μ) ÷ s/sqrt(n)

Test statistic : (22.4 - 21) ÷ 6/sqrt(36)

Test statistic : 1.4 ÷ 1

Test statistic = 1.4000

Pvalue : Using the Test statistic value at α = 0.05 ; One - tail test = 0.0807

The t critical value using a critical value calculator ; DF = (n - 1) = 36 - 1 = 35 ; α = 0.05 = 1.69

Decision region :

Reject H0 if

|Test statistic| > |critical value|

1.4 < 1.69

Hence, we fail to reject H0

There isn't enough evidence they delivery time has been reduced below previous mean
