Compare 0.3 and 0.03

Sidana [21]

0.3 is greater then 0.03 because it has less 0's, if you want how they are alike just message me.

Proportionally means

Bess [88]

Answer:

2 fractions are equal

Step-by-step explanation:

We say that two quantities are proportional if one is always the same multiple of the other.

Say a recipe calls for 2 cups of flour to 3 eggs. That proportion, 2 cups flour : 3 eggs, will always stay the same, no matter how many serving we make. If we make 2 servings, we'd double to 4 cups and 6 eggs, but that wouldn't change the proportion. After all,

$\frac{2}{3}=\frac{4}{6}$

The mean breaking strength of yarn used in manufacturing drapery material is required to be at least 100 psi. Past experience ha

Aleks04 [339]

Answer:

Step-by-step explanation:

Given that:

Mean μ= 100

standard deviation σ = 2.6

sample size n = 9

sample mean X = 100.6

The null hypothesis and the alternative hypothesis can be computed as follows:

$H_o : \mu \leq 100$

$H_1 :\mu > 100$

The numerical value for the test statistics is :

$z = \dfrac{x - \mu}{\dfrac{\sigma}{\sqrt{n}}}$

$z = \dfrac{100.6- 100}{\dfrac{2.6}{\sqrt{9}}}$

$z = \dfrac{0.6}{0.8667}$

z = 0.6923

At ∝ = 0.05

$t_{\alpha/2 } = 0.025$

The critical value for the z score = 0.2443

From the z table, area under the curve, the corresponding value which is less than the significant level of 0.05 is 1.64

P- value = 0.244

c> If the true population mean is 101.3 ;

Then:

$z = \dfrac{x - \mu}{\dfrac{\sigma}{\sqrt{n}}}$

$z = \dfrac{101.3- 100.6}{\dfrac{2.6}{\sqrt{9}}}$

$z = \dfrac{0.7}{0.8667}$

z = 0.808

From the normal z tables

P value = 0.2096

The value of a baseball player's rookie card began to increase once the player retired. When he retired in 1996 1996 his card w

Katena32 [7]

Answer:

Part 1) The equation is $y=1.92x+8.76$

Part 2) The value of the card in 2006 was $\$27.96$

Step-by-step explanation:

Part 1) Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation

Let

x -----> the number of years since 1996

y ----> the value of the card

we know that

The linear equation in slope intercept form is

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem

we have that

1) The value of the card has increased by $ 1.92 each year since 1996

so

The unit rate or slope of the linear equation is $m=1.92\frac{\$}{year}$

2) When he retired in 1996 his card was worth $ 8.76

Remember that the y-intercept is the value of y when the value of x is equal to zero

In this problem, the y-intercept is the value of the card when the year is 1996 (the number of years is zero)

so

The y-intercept is the point (0,8.76)

$b=\$8.76$

substitute the values in the linear equation

$y=1.92x+8.76$

This relation is not proportional, because the linear equation not passes trough the origin

Part 2) What was the value of the card in 2006?

Determine the number of years since 1996

x=2006-1996=10 years

substitute the value of x in the equation and solve for y

$y=1.92(10)+8.76$

$y=\$27.96$
