The true statement is that the p-value is a probability that measures the support (or lack of support) for the null hypothesis.
How to determine the true statement?In a statistical test, the p-value validates or invalidates the null hypothesis
This means that
If p > α, then we accept the null hypothesisOtherwise, the null hypothesis is rejectedSo the true statement about the p value is that it measures the support (or lack of support) for the null hypothesis.

The function t(x) = (x-4)² + 3 is a quadratic function.
How to determine the quadratic function?A quadratic function has a leading exponent of 2
This means that the highest power of a quadratic function is 2
From the list of given options, the function t(x) = (x-4)² + 3 has a leading exponent of 2
Hence, the function t(x) = (x-4)² + 3 is a quadratic function.

there r 12 fish tanks
each fish tank has 20 quarts
every 10 gallons eqal 1 teaspoon
how many teaspoons for the fish tanks
Answer:
six teaspoons
Step-by-step explanation:
12 fish tanks, each 20 quarts
12x20=240 quarts in 12 tanks
we need to convert quarts to gallons
4 quarts equal one gallon, so
240/4=60 gallons in 12 tanks
60 gallons divided by every 10 gallons equal six teaspoons.

Scientists claim that a type of insect inherits wing colors in a ratio of 3:3:1 of black, red, and yellow. A sample of this insect was randomly chosen and it was observed that 42 had black wings, 38 had red wings, and 10 had yellow wings. What is the approximate P-value for the chi-square goodness of fit test
The p-value is 0.622 for the sample of this insect was randomly chosen and it was observed that 42 had black wings, 38 had red wings, and 10 had yellow wings.
What is the chi-square test?A hypothesis testing method is the Chi-square test. Two popular Chi-square tests involve comparing observed and expected frequencies in one or more categories.
The expected proportions are:
3/7, 3/7, 1/7 respectively
Test stasisttics = 0.978
Df = n -1 = 3 - 1 = 2
P-value = 0.622
Thus, the p-value is 0.622 for the sample of this insect was randomly chosen and it was observed that 42 had black wings, 38 had red wings, and 10 had yellow wings.

What is the addition rule of size for two subsets?For two subsets A and B of the universal set U, we have:
[tex]n(A \cup B) = n(A) + n(B) - n(A \cap B)[/tex]
Assume that:
A and B be the subsets of what happens on each day.
Then in the days of last several weeks , we take:
A = set of days which had rainB = set of days which had high winds,then, as per the data given, we get:
n(A) = number of days seeing rain = 67n(B) = number of days seeing high winds = 23 n(A ∩B) = number of days seeing both rain and high winds = 13Thus, we get:
[tex]n(A \cup B) = n(A) + n(B) - n(A \cap B)\\n(A \cup B) = 67 + 23 - 13 = 77[/tex]
Thus, n(A ∪B) = number of days seeing either rain or high winds = 77
Thus, the number of days that had either rain or high winds for the considered case is 77

The sum of the areas of two circles is 80 square meters.find the length of a radius of each circle is one of them is twice as long as the other
Answer:
4 For Small
8 For big
Step-by-step explanation:
80 Square Inches in terms of pie, since one of the radius points are 2 times the other we can setup a equation
(Leaving out pi for simplicity)
R^2 + 2R^2= 80
Now since R is doubled in spot we can plug in points until we get the answer
1:2 (Too small)
2:4 (Too Small)
3:6 (Too small)
4:8 (Fits)
If we plug 4 for R it satisfies the equation for our criteria.

Answer:
x = ±6
Step-by-step explanation:
→ Add 12 to both sides
1/3 x² = 12
→ Multiply both sides by 3

What is the transformation of figure?Transformation of a figure is to change the size, shape or the position of a figure to create a new figure for required use.
The reflection of a plane or shape is flipping the original figure with respect to a reference line. The rule of reflection about x and y-axis is given below,
Reflection about x-axis [tex](x,y)-- > (x,-y)[/tex]Reflection about y-axis [tex](x,y)-- > (-x,y)[/tex]The given figure in the graph is reflected about y-axis. Thus, the rule for the transformation is,
