Answer:

-s-6>-7 (top right)

Step-by-step explanation:

s = -18 > means what is on the left is bigger than what is on the right

top right one = - s - 6 > - 7

top right one = - ( - 18) - 6 > -7

top right one = 18 - 6 > -7

top right one = 12 is bigger than -7

How many plants x should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)? expr

AnnZ [28]

There are 5 plants x that should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)

<h3>Further explanation </h3>

Maria wants to plant a small tomato garden in her yard. She bought 25 tomato plants, and she has read that ideally tomatoes are planted in a square grid to help them pollinate each other, as shown in the picture below.

How many plants x should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)? Express your answer as an integer.

If the gardener has x plants in each of her x rows, then the total number of plants will be $x^2$ .

Since there are 25 total plants, the correct value of x will satisfy the equation $x^2 = 25$

By taking the square root of both sides and note that 25 has both a positive and a negative square root because you can't have a negative number of plants, hence you only want the positive square root:

You can solve this part simply by simple arithmetic.

$x^2 = 25,$ so $x = 5,$

G(x) = - 3x - 8<br><br> g (____) =10

Alex73 [517]

Answer: 6

-3x-8=10
-3x=18
x=6

When g(x) is equal to 10, x is equal to 6. So, g(6)=10

For this question you will need to analyze data given in file seed Emergence. For your convenience, the data is posted as a text

Mrac [35]

Answer:

A) You will get the Mean, Sample variance and standard deviation, Minimum, maximum, range, and Boxplot.

B) The two-way ANOVA (analysis of variance) model is used for the two factors.

C) Outputs are obtained

D) Here, P-value (= 0.0377) < α (= 0.05). There is evidence that the treatments differ with respect to emerging plants.

Step-by-step explanation:

(A)

Use the MegaStat add-in in Excel to draw the boxplot and to find; the group counts, means, standard deviations, variances, minimums, maximums, and ranges for the 5 treatment groups.

In another Excel worksheet. Enter the data in 5 different columns, each column representing a treatment, and the first row holding the treatment names.

Go to Add-Ins > MegaStat > Descriptive Statistics.

Enter Sheet1!$A$1:$E$5 in Input range.

Tick on Mean, Sample variance and standard deviation, Minimum, maximum, range, and Boxplot.

Click OK.

(B)

Since there are two factors affecting the outcomes- the five treatments (Control, Arasan, Spergon, Semesan, and Fermate), and the four blocks, the two-way ANOVA (analysis of variance) model must be used.

(C)

We have used the Data Analysis tool-pack in Excel to construct the analysis of variance table.

We have arranged the data and entered it as follows:

Control, Arasan, Spergon, Semesan, Fermate

Block 1: 86 98 96 97 91

Block 2: 90 94 90 95 93

Block 3: 88 93 91 91 95

Block 4: 87 89 92 92 95

Go to Data > Data Analysis > Anova: Two-Factor Without Replication > OK.

In Input Range, enter $A$1:$E$6; tick on labels, enter Alpha as 0.05, and click OK.

The following output is obtained. Note that the analysis of variance table is given under “ANOVA” in the output.

(D)

In the analysis of variance table above, the “Rows” under “Sources of Variation” correspond to the treatments (as the observations under each treatment are noted along a row), whereas the “Columns” title relates to the block effects.

The P-value for Rows, hat is, for the treatments is 0.0377 (4 decimal places).

The level of significance is given as α = 0.05.

In this case, the null hypothesis is that, there is no significant difference between the 5 treatments, and the alternative hypothesis should be that, not all the treatments have the same effect.

The rejection rule for a test using the P-value is: Reject the null hypothesis, if P-value ≤ α. Otherwise, fail to reject the null hypothesis.

Explain when you must write the number 1, and when you do not need to.

stepan [7]

Answer:

The number 1 is not necessary when expressing powers of one. For example, you needn't write "5" as $5^{1}$ .
