The lengths of two sides of a triangle are 10 inches and 4 inches. Which of the following dimensions is the third side of this triangle?
A.
4 inches
B.
5 inches
C.
6 inches
D.
7 inches
Answer:
The answer would be A.) 4 inches
Step-by-step explanation:
It is A. because if the base of the triangle is 10 inches and one side is 4 then the two sides of the trianlge would be the same they are congruent so if one side of the triangle is 4 then the other side of the triangle is 4.

Answer:
a triangle
Step-by-step explanation:
the definition of a triangle is a shape with 3 sides and the shape that is shown has 3 sides.
A square is getting larger. The sides are each growing at a constant rate of 3 in min . At what rate is the area of the square growing the moment its area is 25 in2
Answer: [tex]30\ in.^2/min[/tex]
Step-by-step explanation:
Given
The side of a square is increasing at the rate of [tex]\frac{dl}{dt}=3\ in./min[/tex]
The area of the square is the square of the side length
[tex]A=l^2[/tex]
when the area is [tex]25\ in.^2[/tex], its side must be [tex]5\ in.[/tex]
Differentiate area w.r.t time
[tex]\Rightarrow \dfrac{dA}{dt}=2l\dfrac{dl}{dt}\\\\\text{Insert the value}\\\Rightarrow \dfrac{dA}{dt}=2\times 5\times 3\\\\\Rightarrow \dfrac{dA}{dt}=30\ in.^2/min[/tex]

The ratio x : y is equal to 4x : 3.
Work out the value of y.
y =
Answer:
y=3/4
Step-by-step explanation:
4x/3 = x/y
or, 1/y= 4/3
or, y=3/4
Answer:
y = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Express the ratios in fractional form
[tex]\frac{x}{y}[/tex] = [tex]\frac{4x}{3}[/tex] ( cross- multiply )
4xy = 3x ( divide both sides by 4x )
y = [tex]\frac{3x}{4x}[/tex] = [tex]\frac{3}{4}[/tex]

Chris surveyed the sixth grade at his school and found that 20% of the students walk to school. If 60 students walk to school, then how many students are in the 6th grade?
[tex] \huge \mathfrak{ Answer : - }[/tex]
60 students walk to school, which is 20 % of the total students studying there,
so, let the the total number of students be " x "
now, we know
=》
[tex]20 \% \: \: of \: \: x = 60[/tex]
=》
[tex] \dfrac{20}{100} \times x = 60[/tex]
=》
[tex] \dfrac{1}{5} \times x = 60[/tex]
=》
[tex]x = 60 \times 5[/tex]
=》
[tex]x = 300[/tex]
hence, the total number of students :
x = 300
Answer:
simple answer 300
Step-by-step explanation:
20%=60 students. 100%/20%=5. 60*5=300 students
An important problem in industry is shipment damage. A electronics distribution company ships its product by truck and determines that it cannot meet its profit expectations if, on average, the number of damaged items per truckload is greater than 12. A random sample of 12 departing truckloads is selected at the delivery point and the average number of damaged items per truckload is calculated to be 9.4 with a calculated sample of variance of 0.64. Select a 99% confidence interval for the true mean of damaged items.

Bags of a certain brand of tortilla chips claim to have a net weight of 14 ounces. The net weights actually vary slightly from bag to bag and are normally distributed with mean μ. A representative of a consumer advocacy group wishes to see if there is any evidence that the mean net weight is less than advertised.
For this, the representative randomly selects 16 bags of this brand and determines the net weight of each. He finds the sample mean to be 13.82 and the sample standard deviation to be 0.24.
Use these data to perform an appropriate test of hypothesis at 5% significance level.
Answer:
The p-value of the test is of 0.0045 < 0.05, which means that there is enough evidence to reject the null hypothesis and accept the alternate hypothesis that the mean net weight is less than advertised.
Step-by-step explanation:
Bags of a certain brand of tortilla chips claim to have a net weight of 14 ounces. A representative of a consumer advocacy group wishes to see if there is any evidence that the mean net weight is less than advertised.
At the null hypothesis, we test that the mean is of 14, that is:
[tex]H_0: \mu = 14[/tex]
At the alternate hypothesis, we test tha tthe mean is less than advertised, that is, less than 14. So:
[tex]H_a: \mu < 14[/tex]
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
14 is tested at the null hypothesis:
This means that [tex]\mu = 14[/tex]
For this, the representative randomly selects 16 bags of this brand and determines the net weight of each. He finds the sample mean to be 13.82 and the sample standard deviation to be 0.24.
This means that [tex]n = 16, X = 13.82, s = 0.24[/tex]
Test statistic:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{13.82 - 14}{\frac{0.24}{\sqrt{16}}}[/tex]
[tex]t = -3[/tex]
P-value of the test and decision:
The p-value of the test is the probability of finding a sample mean below 13.82, which is the p-value of t = -3, using a left-tailed test with 16 - 1 = 15 degrees of freedom.
With the help of a calculator, the p-value is of 0.0045.
The p-value of the test is of 0.0045 < 0.05, which means that there is enough evidence to reject the null hypothesis and accept the alternate hypothesis that the mean net weight is less than advertised.
