The appropriate null and alternate hypotheses are (d) H0: p = 0.10 and H1: p ≠ 0.10
How to determine the hypotheses?From the question, we understand that:
The proportion of reports that have their cars stolen is given as 10%
Null hypothesis is represented with the equality sign.
So, the null hypothesis is H0: p = 0.10
The alternate hypothesis is represented with the unequal sign.
So, the alternate hypothesis is H1: p ≠0.10
Hence, the appropriate hypotheses are (d) H0: p = 0.10 and H1: p ≠ 0.10

What is the measure of each angle in Megan’s triangle?
m∠A =
°
m∠B =
°
m∠C =
°
Answer:
A, C and D are true statements.
Step-by-step explanation:
Megan constructed triangle ABC.
In Megan’s triangle, m∠A is represented by x°.
Therefore, ∠A = x°
For m∠B is 4 times greater than m∠A
Therefore, ∠B = 4x°
For m∠C is 30° less than 5 times m∠A.
Therefore, ∠C = 5x°-30°
ABC is a triangle.
Sum of all angles of a triangle is 180°. Angle sum property of triangle.
m∠A + m∠B + m∠C = 180°
x° + 4x° + 5x°-30° = 180°
x° = 15°
True Statements are:
A) m∠A = x°
C) m∠B = (4x)°
D) m∠C = (5x – 30)°

4 1/4 - 5/6 I don’t understand pls help
Answer:
1/6 or 0.167
Step-by-step explanation:
First understand that 4 x 1/4 is equal to 1, then replace it in the equation
1 - 5/6
Turn the whole number into a fraction that can be computed
6/6 - 5/6
Solve the equation
6/6 - 5/6 = 1/6
If you need it as a decimal enter it in a calculator and get
0.16666666667
Since the 6 is repeating you can just round that to

The area of rectangle is ( 30x²y + 20xy ) cm² and its breadth is 10xy cm .Find its length.
Subtract the quotient when 20x⁴y² is divided by 5x³y from the product of 2x and 3y.
Step-by-step explanation:
1) The area of rectangle is ( 30x²y + 20xy ) cm² and its breadth is 10xy cm .Find its length....
= Solution ,
Length ( L ) = ?
breadth ( b ) = 10xy cm
area ( a ) = ( 30x² + 20xy )
Now ,
area ( a ) = l × b
or, ( 30x²y + 20xy ) = L × 10xy cm
[tex]or,\frac{30 {xy + 20xy}^{2} }{10xy} = l \\ [/tex]
[tex]or, \: l = 3 {x}^{2 - 1} + 2cm[/tex]
[tex]\boxed{\sf{l = (3x+2)cm}}[/tex]
2) Subtract the quotient when 20x⁴y² is divided by 5x³y from the product of 2x and 3y.
= Solution,
[tex] = \frac{20 {x}^{4} {y}^{2} }{5 {x}^{3} y} \\ [/tex]

Glaucoma is a disease of the eye that is manifested by high intraocular pressure. The
distribution of intraocular pressure in the general population is approximately normal with
mean 16 mm Hg and standard deviation 3.2 mm Hg. If the normal range for intraocular
pressure is between 10 and 22 mm Hg, than what proportion of the general population would
fall within this range?
A z-table is also known as the standard normal distribution table. The percentage of the population that would fall in the 10 to 22 mm Hg range is 0.9386.
What is a Z-table?A z-table also known as the standard normal distribution table, helps us to know the percentage of values that are below (or to the left of the Distribution) a z-score in the standard normal distribution.
Given the mean and the standard deviation are 16mmHg and 3.2 mmHg, therefore, the percentage of the population whose blood pressure will fall in the range of 10 to 22 mm Hg are,
[tex]P(10 < x < 22) = P(\dfrac{10-16}{3.2} < Z < \dfrac{22-16}{3.2})[/tex]
[tex]= P(-1.875 < Z < 1.875)\\\\=P(Z < 1.875)-P(Z < -1.875)\\\\= 0.9693-0.0307\\\\= 0.9386[/tex]
Hence, the percentage of the population that would fall in the 10 to 22 mm Hg range is 0.9386.

Daniel has a bag that contains pineapple chews, apple chews, and watermelon chews. He performs an experiment. Daniel randomly removes a chew from the bag, records the result, and returns the chew to the bag. Daniel performs the experiment 51 times. The results are shown below:
A pineapple chew was selected 21 times.
A apple chew was selected 12 times.
A watermelon chew was selected 18 times.
Based on these results, express the probability that the next chew Daniel removes from the bag will be a flavor other than watermelon as a decimal to the nearest hundredth.
The probability that the next chew Daniel removes from the bag will be a flavor other than watermelon is 0.65
How to determine the probability?The distribution of the fruits is given as:
Pineapple = 21Apple = 12Watermelon = 18The probability that the next chew Daniel removes from the bag will be a flavor other than watermelon is:
P = (Apple + Pineapple)/Total
This gives
P = (12 + 21)/(21 + 12 + 18)

P = 0.65

The mass of 2 bags, which is filled by Lynn each with 2 kilograms 450 grams of sand, is less than 5 kilograms.
How to measure the weight?Weight measurement is the measurement of the heaviness of a object. The units of weight measurement are pounds, grams, kilograms etc.
There is total 1000 grams in one kilogram of weight measurement.
Lynn filled each of three bags with 2 kilograms, 450 grams of sand. There is total 1000 grams in one kilogram of weight measurement. Thus, the kilogram in 450 grams is,
[tex]x=\dfrac{450}{1000}\\x=0.45\rm\; kg[/tex]
Thus, weight in one bag is,
[tex]W=2+0.45\\W=2.45\rm\; kg[/tex]
The weight in two bags is,
[tex]2W=2.45+2.45\\2W=4.9\rm\; kg[/tex]

A right triangle has side lengths 9, 40, and 41 as shown below.
B
40
Use these lengths to find cosB, tanB, and sin B.
9
Answer:
cos B = 9/41
tan B = 40/9
sin B = 40/41
Step-by-step explanation:
There is no picture, so I am making a few assumptions.
I am assuming that angle C is the right angle and is opposite 41.
I am also assuming that angle B is formed by the sides that measure 9 and 41. The hypotenuse is 41.
For angle B, the adjacent leg is 9, and the opposite leg is 40.
cos B = adj/hyp = 9/41
tan B = opp/adj = 40/9
sin B = opp/hyp = 40/41
