Question

Solve the equation: x-14=20

x -14 = 20

x = 20 + 14

x = 34

34 is your answer

----------------------------

check

Hello!

Answer: x=34 or 34=x *The answer must have positive sign.*

Explanation:

This question's it's about the adding the property of equality.

First, you add by 14 from both sides of an equation.

$x-14+14=20+14$

And then simplify.

$20+14=34$

$x=34$

Hope this helps!

Answer:

The calculated value t= 3,947 > 2.0301 at 0.05 level of significance ( two tailed test) with 35 degrees of freedom.

Null hypothesis is rejected

There is no strong evidence that they have attained their fuel economy goal.

Step-by-step explanation:

Step (i):-

A company with a large fleet of cars hopes to meet the goal of 38.2 mpg or better for their fleet of cars.

Population mean 'μ' = 38.2mpg

Given the gasoline usage for 36 company trips chosen at random, finding a mean of 40.20 mpg and a standard deviation of 3.04 mpg.

Sample size 'n' = 36

mean of the Sample 'x⁻' = 40.20mpg

standard deviation of the Sample 'S' = 3.04 mpg.

Step(ii):-

Null hypothesis: H₀: 'μ' = 38.2mpg

Alternative hypothesis: H₁: 'μ' ≠ 38.2mpg

Level of significance ∝=0.05

The test of hypothesis

$t = \frac{x^{-} - mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{40.20- 38.20}{\frac{3.04}{\sqrt{36} } } = 3.947$

The degrees of freedom ν= n-1 = 36-1 =35

The tabulated value t₀.₀₅ = 2.0301 at 0.05 level of significance ( two tailed test) with 35 degrees of freedom.

The calculated value t= 3,947 > 2.0301 at 0.05 level of significance ( two tailed test) with 35 degrees of freedom.

Null hypothesis is rejected

Conclusion:-

There is no strong evidence that they have attained their fuel economy goal.

Answer: norm of reaction

Step-by-step explanation:

norm of a reaction which is the capacity of a genotype to produce different phenotypes in response to the environment. The group of phenotypic expressions under different environmental conditions. A organism can own all the genetic complements necessary to fully development. However, if there is no suitable nutricion, the development does not occur. The environment only changes the phenotypic characteristics within certain limits ruled by the genotype (norm of reaction). The genotype do not determine a phenotypes, but a amount of possible phenotypes, a norm of reaction. A certain phenotype will materialize itself depending on the interaction of a certain genotype with the environment.
