The whale is longer because 1 meter is 100cm and 100cm X 4 = 400cm/4m and 24m divided by 100cm = 2400cm

Teen Court is a juvenile diversion program designed to circumvent the formal processing of first-time juvenile offenders within

valentinak56 [21]

Answer:

Z-statistic = 1.4017 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

The data suggest that the true proportion of Teen Court individuals who recidivate during the specified follow-up period differs from the proportion of Department of Juvenile Services individuals

Step-by-step explanation:

Step(i):-

Given first sample size (n₁ ) = 57

Of the 57 Teen Court individuals, 18 subsequently recidivated during the 18-month follow-up period

First sample proportion

$p^{-} _{1} = \frac{x_{1} }{n_{1} } = \frac{18}{57} =0.3157$

Second sample proportion

$p^{-} _{2} = \frac{x_{2} }{n_{2} } = \frac{11}{54} =0.2037$

Null Hypothesis : p₁⁻ = p₂⁻

Alternative Hypothesis : p₁⁻ ≠ p₂⁻

Step(ii):-

Test statistic

$Z = \frac{p_{1} ^{-} -p^{-} _{2} }{\sqrt{PQ(\frac{1}{n_{1} } +\frac{1}{n_{2} } )} }$

where

$P = \frac{n_{1}p^{-} _{1} +n_{2} p^{-} _{2} }{n_{1} +n_{2} }$

$P = \frac{57 X0.3157+0.2037X54}{54+57} = 0.2612$

Q = 1 - P = 1 - 0.2612 = 0.7387

$Z = \frac{0.3157-0.2037}{\sqrt{0.2612 X0.7387 (\frac{1}{57} +\frac{1}{54} )} }$

Z = 1.4017

Level of significance ∝ =0.05

The tabulated value Z₀.₀₅ = 1.96

Z-statistic = 1.4017 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

The data suggest that the true proportion of Teen Court individuals who recidivate during the specified follow-up period differs from the proportion of Department of Juvenile Services individuals

Help! 20 points, I can’t figure it out and my daughter is in 7th grade. The hard middle school years aha

Shtirlitz [24]

Answer:

(0, 0), (1, 4), (2, 8); 4

(0,0), (3, 1), (6, 2); 1/3

(0,0), (4, 2), (8, 4); 0.5

Step-by-step explanation:

Part a:

Choose any 3 values for x. Plug them into the equation and find the corresponding y values.

y = 4x

Let x = 0:

y = 4x = 4(0) = 0

First point: (0, 0)

Let x = 1:

y = 4x = 4(1) = 4

Second point: (1, 4)

Let x = 2:

y = 4x = 4(2) = 8

Third point: (2, 8)

Answer to part a:

(0, 0), (1, 4), (2, 8)

The constant of proportionality is k in the equation of a proportional relationship, y = kx

y = 4x

Constant of proportionality: 4

Part b:

y = (1/3)x

Let x = 0, 3, 6 (one at a time)

For x = 0, y = (1/3)(0) = 0

For x = 3, y = (1/3)(3) = 1

For x = 6, y = (1/3)(6) = 2

Answer to part b:

(0,0), (3, 1), (6, 2)

Constant of proportionality: 1/3

Part c:

y = 0.5x

Let x = 0, 4, 8 (one at a time)

For x = 0, y = (0.5)(0) = 0

For x = 4, y = (0.5)(4) = 2

For x = 8, y = (0.5)(8) = 4

Answer to part b:

(0,0), (4, 2), (8, 4)

Constant of proportionality: 0.5
