How much does 8.20 X 10-3dm3 (1dm3 = 1L) sample of aluminum weigh in grams? centimeters?

m_a_m_a [10]

Answer:

8.20 grams ; 8.20 cm³

Step-by-step explanation:

At first convert it to m³ from dm³

we know,

1 dm³ =10⁻³ m³

∴ 8.20 X 10⁻³dm3 = 8.20 X 10⁻³ x 10⁻³ m³

=8.20 X 10⁻⁶ m³

m³ to gram :

1 m³ = 10⁶ grams

∴ 8.20 X 10⁻⁶ m³ = (8.20 X 10⁻⁶x10⁶) grams

= 8.20 grams

m³ to cm³ :

1m³ = 10⁶ cm³

∴8.20 X 10⁻⁶ m³ = (8.20 X 10⁻⁶ x 10⁶) cm³

=8.20 cm³

Note:

1 cm³ = 1 gram

What are the rational roots for the polynomial shown below? x³ + 5x²-8r-20=0

inessss [21]

$x ^{3} + 5x {}^{2} - 8 r - 20 = 0 \\ x { }^{3} + 5x {}^{2} - 8r - 20(x {}^{3} + 5x {}^{2} ) = 0 - (x {}^{3} + 5x {}^{2} ) \\ - 8r - 20 = - (x {}^{3} + 5x {}^{2} ) \\ \\ - 8r - 20 + 20 = - (x {}^{3 } + 5x {}^{2} ) + 20 \\ \\ - 8r = x {}^{3} - 5x {}^{2} + 20 \\ \\$

A consumer product magazine recently ran a story concerning the increasing prices of CINCO-FONES. The story stated that CINCO-FO

Leviafan [203]

Answer:

Check the explanation

Step-by-step explanation:

We have:

Null Hypothesis:

H o:μ = 215

Alternate Hypothesis:

Η α :μ> 215 This is a one tailed test

Standardized value to be tested:

$\frac{new Mean Value - nullValue}{SE}$ == $\frac{245.23 – 215}{15.62}$ -= 1.93

Since this is a one tailed test, critical t value which occurs at 95% confidence level is 1.943.

Since 1.93 < 1.943, we can say that At α = 0.05, there is insufficient evidence to indicate that the mean price of all digital cameras exceeds $215.00.

To make it sufficient, we need value more than 1.943.

At α = 0.10, critical t value is 1.440 (less than 1.93) which makes it sufficient.
