Answer:

15 Inch

Step-by-step explanation:

The formula is

$h-15=3.2t\\$

To find initial height, put t = 0.

$h-15=3.2\times 0\\h-15=0\\h=0+15 \\h=15$

Hence, initial height of the plant = 15 inch

n 2018, homes in East Baton Rouge (EBR) Parish sold for an average of $239,000. You take a random sample of homes in Ascension p

Olenka [21]

Answer:

Conclusion

There is no sufficient evidence to conclude that the mean of the home prices from Ascension parish is higher than the EBR mean

Step-by-step explanation:

From the question we are told that

The population mean for EBR is $\mu_ 1 = \$239,000$

The sample mean for Ascension parish is $\= x_2 = \$246,000$

The p-value is $p-value = 0.045$

The level of significance is $\alpha = 0.01$

The null hypothesis is $H_o : \mu_2 = \mu_1$

The alternative hypothesis is $H_a : \mu_2 > \mu_1$

Here $\mu_2$ is the population mean for Ascension parish

From the data given values we see that

$p-value > \alpha$

So we fail to reject the null hypothesis

So we conclude that there is no sufficient evidence to conclude that the mean of the home prices from Ascension parish is higher than the EBR mean

Which system of equations can be used to find the roots of the equation 12 x 3-5x=2 x 2+x+6

kirill [66]

Answer:

Option (a) is correct.

The system of equation becomes

$y=12x^3-5x\\\\ y=2x^2+x+6$

Step-by-step explanation:

Given : Equation $12x^3-5x=2x^2+x+6$

We have to construct a system of equations that can be used to find the roots of the equation $12x^3-5x=2x^2+x+6$

Consider the given equation $12x^3-5x=2x^2+x+6$

To construct a system of equation put both sides of the given equation equal to a same variable.

Let the variable be "y", Then the equation $12x^3-5x=2x^2+x+6$

becomes,

$12x^3-5x=y=2x^2+x+6$

Thus, The system of equation becomes

$y=12x^3-5x\\\\ y=2x^2+x+6$

Option (a) is correct.

Donna's company reimburses her expenses on food, lodging, and conveyance during business trips. The company pays $50 a day for f

Maksim231197 [3]

Multiply the number of days, x by 50 per day to get 50x.

Next multiply the number of miles driven to the amount she gets per mile: 0.60 x 200 = $120

Now add both together to equal the total of 1620.

The equation becomes: 50x +120 = 1620

50x +120 = 1620

Step 1: subtract 120 from both sides ( subtraction property of equality):

50x = 1500

Step 2: Divide both sides by 50 ( division property of equality):

x = 1500 / 50

x = 30

The trip lasted 30 days.
