The plots are experimental units in this study, then the farmer is conducting an experiment to determine which variety of apple tree, fuji or gala, will produce more fruit in his orchard. So ,the answer is the plots.
Based on the given conditions.
First a farmer is conducting an experiment to determine which variety of apple tree, fuji or gala, will produce more fruit in his orchard.The orchard is divided into equally sized square plotsHe has 10 trees of each variety and randomly assigns each tree to a separate plot in the orchard.Since the plots are the things being measured, they serve as the experimental units. The explanatory variable is the type of apple trees because they induce change in the experimental unit by undergoing two distinct treatments. The experiment is being run by the farmer, and the outcome is the quantity of apples. Since each plot is being investigated separately, the orchard as a whole has no bearing on the experiment.Therefore,
The plots are experimental units in this study, then the farmer is conducting an experiment to determine which variety of apple tree, fuji or gala, will produce more fruit in his orchard. So ,the answer is the plots.

What is the value of “c”
The equation can be solved as below
What is an equation?
A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The definitions of the word equation and its cognates in various languages might vary slightly. For instance, in French, an equation is defined as having one or more variables, but in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign. Finding the values of the variables that result in the equality is the first step in solving an equation with variables. The unknown variables are also known as the variables for which the equation must be solved, and the unknown variable values that fulfill the equality are known as the equation's solutions. Equations come in two varieties: identities and conditional equations.
The equation can be solved as
x² + 16x + c = 0

What is Algebraic expression ?
Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables..
Here, the given equation is :
y = -3x + 1
which passes through point (-7,-2)
Let us first find the slope of line m which is parallel to the liney = -3x + 1 using point-intercept equation of line that is given by :
y = mx + c....(1)
y = -3x + 1
comparing above equation with equation (1) we get
m = -3
Now, the slope of line parallel to line y = -3x + 1 will have same slope that is m = -3
Now, Let us find the equation of the line using point-slope equation of line :
(y-y₁) = m(x-x₁)
Substituting all the values in above equation to get the equation of line :
(y-(-2)) = -3(x-(-7))
(y+2) = -3x-21
y = -3x -21 -2
y = -3x +23
Therefore, the equation of line which passes through point (-7,-2) is y = -3x +23.

A virus is spreading around Kingwood. At the moment, 368 people are infected. If the virus is spreading at a rate of 6% each day, how many people in all will have caught the virus in 5 days?
Answer:
478 / 479
Step-by-step explanation:
6% of 368 is 22.08.
5 days = 6% x 5 = 30%.
30% of 368 = 110.4
110.4 + 368 = 478.4
492 people will be infected with the virus in 5 days.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
We have,
Number of people infected = 368
Rate of spreading = 6%
We can make an equation for the number of people infected in x days.
y = 368 x [tex](106/100)^x[/tex]
y = 368 x [tex]1.06^x[/tex]
Substitute x = 5
y = 368 x [tex]1.06^5[/tex]
y = 492.467
y = 492

Strontium-90 (Sr-90) has a half-life of approximately 29 years. Let the initial amount of Sr-90 in a sample be 100g. If the decay function s(y)=100*0.5^y/29 expresses the amount of Sr-90 that remains in the sample after y years, in how many years will 1g of Sr-90 be left? Round up your answer to the nearest number of years
Answer: Approximately 193 years
=======================================================
Work Shown:
y = number of years
s(y) = amount of Strontium-90 (Sr-90) in grams
We plug in s(y) = 1 and solve for y to determine how long it takes for the initial 100 gram sample to decay to 1 gram.
s(y)=100*0.5^(y/29)
1=100*0.5^(y/29)
1/100 = 0.5^(y/29)
0.01 = 0.5^(y/29)
Log[ 0.01 ] = Log[ 0.5^(y/29) ] .... see note1 below
Log[ 0.01 ] = (y/29)*Log[ 0.5 ] .... see note2
(y/29)*Log[ 0.5 ] = Log[ 0.01 ]
y/29 = Log[ 0.01 ]/Log[ 0.5 ]
y = 29*Log[ 0.01 ]/Log[ 0.5 ]
y = 192.671829503468
y = 193

Second answer: Congruent angles are two or more angles that are identical to each other. Thus, the measure of these angles is equal to each other.
Third answer: The transitive property of equality formula is given as follows: If x = y and y = z, then x = z. Where x, y and z belongs to the same category elements. For example, if “x” represents the measurement of a line segment, then y and z should represent the measurement of the line segment.
Fourth answer: Congruent segments are segments that have the same length. ≅ Points that lie on the same line are called collinear.

What are angles?In Euclidean geometry, an angle is made up of two rays that share a terminal and are referred to as the angle's sides and vertices, respectively. Angles can be formed by two rays in the plane where they are placed. Additionally, when two planes overlap, angles are created. Dihedral angles are what they are called. When two straight lines or rays intersect at a single point, an angle is created. The vertex of an angle is the location where two points converge.

The marked angles in red are congruent to one another, which refers to the 'A' in SAS. We have two pairs of congruent sides, and a pair of congruent angles between those sides. This allows us to use the SAS rule.

The t-statistic is the t-value at the intersection of the row for DF = 25 and the 0.025 (one-tail) column is 2.06
How to calculate confidence interval for population mean for small sample?If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.
The number of degrees of freedom will be n - k
The confidence level in the confidence interval
The parameters given in the question is;
The number of pizza orders in the sample is n
The sample size = 26
The number of samples used in the estimate, k = 1 group of 26 randomly sampled.
The level of confidence that the interval contains the population mean = 95%
Therefore, the significance level;
α = 1 - 95% = 1 - 95/100
= 0.05
Here α-level for the upper and lower limit of the interval are;
α/2 = 0.05/2 = 0.025 long
The degrees of freedom, DF = n - k
DF = 26 - 1 = 25
The t-statistic is the t-value at the intersection of the row for DF = 25 and the 0.025 (one-tail) column (0.025 two-tail column);
