No, it doesn't show that single individuals under the age of 25 have more insurance claims than the nationwide percent reported by the big insurance firm.

Hypothesis

Null hypothesis : H0: p = 0.68

Alternative hypothesis : Ha: p > 0.68

A random sample of 53 claims showed that 41 were made by single people under the age of 25.

Thus; p^ = 41/53 = 0.7736

The test statistic is

z = (p^ - p_o)/√(p_o(1 - p_o)/n)

z = (0.7736 - 0.68)/√(0.68(1 - 0.68)/41)

z = 0.0936/0.07285

z = 1.28

The p-value from z-score calculator, using z = 1.28, one tail hypothesis and significance level of 0.05,we have;

P(z > 1.28) = 0.100273

The p-value gotten is greater than the significance value and so we fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim.

The surface area and volume of wrappings needed to completely wrap the rectangular box equal \(394.24\) square inches.

Volume is essentially just a measurement of space. Liters (L) and microliters (mL) are the units used to measure a liquid's volume, which is often referred to as capacity. Erlenmeyer, beakers, and graduated cylinders are among the tools used for this measurement.

Total water volume refers to the overall volume of water utilized in large volume horizontal hydraulic fracking activities, including produced water, recycled water, surface water, and groundwater.

Given the following:

\(Volume = 476.16\) cubic inches

\(Length = 4.8\) inches

\(Width = 8\) inches

Find the height \((h)\)  using the volume formula:

\(476.16 = 4.8 * 8 * h\)

\(476.16 = 38.4 * h\)

\(476.16/38.4 = h\)

\(h = 12.4\) inches

Surface area \(= 2(wl + hl + hw) = 2(8 * 4.8 + 12.4 * 4.8 + 12.4 * 8) = 394.24\)

The rectangular garden's width is 15 units, and Gabriella needs 120 meters of fence to enclose it.

The perimeter of a rectangle is the length of its side boundaries. A rectangle's perimeter is equal to twice the product of its length and width.

\(P=2(l+w)\)

In this case, the rectangle's length is (l) and its width is (w).

Assume for a moment that the garden is l units long. The garden is three times longer than it is wide, w. Thus,

\(l=3w\)

Gabriella requires 120 meters of fencing to enclose a square garden. The perimeter of the rectangular garden is the same height as this fence. Thus,

\(P=2(l+w)\\120=2(l+w)\)

Add this equation with the length value from equation 1.

\(120=2(3w+w)\\3w+w=\frac{120}{2} \\4w=60\\w=\frac{60}{4} \\w=15\)

Gabriella needs 120 meters of fence to enclose the rectangular garden, which has a width of 15 units.

Answer:

The variable y should equal 5 2/5 or 5.4 as a decimal.

Step-by-step explanation:

The variable x equals 1 so we can replace x in the equation y = 2/5x + 5 with 1.

y = 2/5(1) + 5

This is our new equation. Any number multiplied by 1 will equal itself so in this case, 2/5 times 1 equals 2/5 or 0.4 in decimal form. Now we can add 2/5 or 0.4 to 5 and we will get 5 2/5 or 5.4. Now we will only have y =  5 2/5 or 5/4 in the equation and this is where we will stop solving for y. In conclusion, y equals 5 2/5 or 5.4. I hope this helps!

Answer:

c = 0.15m + 45

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope and b is the y-intercept

To get the value of m, we can use the slope equation

m = (y2-y1)/(x2-x1)

Let us select two points to use from the table

we have;

(40,51) and (20,48)

So substituting these values;

m = (48-51)/(20-40) = 0.15

So we have the partially completed equation as;

y = 0.15x + b

To get the value of b, we use any of the points

Using the last, we have

51 = 0.15(40) + b

b = 45

So we have the complete equation as;

y = 0.15x + 45

using the terms in the question, we have;

c = 0.15m + 45

The spherical coordinates of the point with rectangular coordinates (2√2, -2√/2, -4√2) are (r, θ, ϕ) = (√42, -π/4, 116.57°). Hence, option (B) is correct.

To solve this problem, we are required to convert rectangular coordinates to spherical coordinates.

The given rectangular coordinates are (2√2, -2√/2, -4√2).

Rectangular coordinates to spherical coordinates conversion

As per the formula of spherical coordinates,r = √(x² + y² + z²)θ = tan⁻¹(y/x)ϕ = cos⁻¹(z/√(x² + y² + z²))

Let's calculate the spherical coordinates of the given rectangular coordinates:

Given rectangular coordinates are x = 2√2, y = -2√/2, and z = -4√2.

Thus, we have r = √(x² + y² + z²)

Here, r = √(2√2)² + (-2√/2)² + (-4√2)²r = √8 + 2 + 32r = √42

Now, we have θ = tan⁻¹(y/x)

Here, θ = tan⁻¹(-1/√2)θ = -π/4

Now, we have ϕ = cos⁻¹(z/√(x² + y² + z²))

Here, ϕ = cos⁻¹(-4√2/√42)ϕ = cos⁻¹(-2/√42)ϕ = 116.57°

So, the spherical coordinates of the point with rectangular coordinates (2√2, -2√/2, -4√2) are (r, θ, ϕ) = (√42, -π/4, 116.57°).

Hence, option (B) is correct.

Step-by-step explanation:

Step-by-step explanation:

Hey there!

1.no Ans:

The equation of a st.line passing through point (3,0) is;

(y-0) = m1(x-3)........(i)

Another equation is,

y = 2/3x+1...........(ii)

Comparing the equation (ii) with y= mx+c. We get;

Slope (m2)= 2/3

As they are parallel lines, m1=m2.

So, putting value of m1 in equation (i).

\(y = \frac{2}{3} (x - 3)\)

\(y = \frac{2}{3} x - 3 \times \frac{2}{3} \)

Therefore the required equation is; y = 2/3x -2.

2.Ans:

The equation of a st.line passing through (4,1) is;

(y-1) = m1(x-4)...........(i)

y = -1/2x +2...............(ii)

From equation (ii)

y = -1/2x+2

Comparing the equation with y = mx+c

Slope (m2)= -1/2

As they are equal m1=m2= -1/2

Putting value of slope in equation (i)

\((y - 1) = \frac{ - 1}{2} (x + 2)\)

\(2(y - 1) = - 1(x + 2)\)

\(2y - 2 = - x - 2\)

\(x + 2y = 0\)

Therefore the required equation is; x+2y=0.

3. no. Ans:

The equation of a st.line passing through point (-1,-1) is ;

(y+1)= m1(x+1)..........(i)

y= -2x-4.....................(ii)

From equation (ii)

Comparing the equation with y = mx+c.

Slope(m2)= -2

As they are parallel lines, m1=m2 = -2.

Putting value of slope in equation (i)

\((y + 1) = - 2(x + 1)\)

\(y + 1 = - 2x - 2\)

\(2x + y + 3 = 0\)

Therefore the required equation is 2x+y+3=0.

4.no Ans:

The equation of a st.line passing through (-4,-5) is;

(y+5) = m1(x+4)..........(i)

y = -2x-5...............(ii)

From equation (ii)

Comparing the equation with y = mx+c, we get;

Slope (m2)= -2

As they are parallel lines, m1=m2= -2

Putting value of slope in equation (i)

\((y + 5) = - 2(x + 4)\)

\(y + 5 = - 2x - 8\)

\(2x + y + 13 = 0\)

Therefore the required equation is 2x+y+13=0.

5.no Ans:

The equation of a st.line passing through (-4,3) is:

(y-3)= m1(x+4).........(i)

y = 1/2x-3.......(ii)

From equation (ii)

Comparing the equation with y= mx+c.

Slope (m2) = 1/2

As they are parallel lines, m1=m2 = 1/2.

Putting value of slope in equation (i)

\((y - 3) = \frac{1}{2} (x + 4)\)

\(2(y - 3) = x + 4\)

\(2y - 6 = x + 4\)

\(x - 2y + 10 = 0\)

Therefore the required equation is; x-2y+10=0.

6.no. Ans;

The equation of a st.line passing through (5,-5) is;

(y+5)= m1(x-5)............(i)

y = -3/2x+2......(ii)

Comparing the equation (ii) with y = mx+c.

Slope(m2)= -3/2.

As they are parallel lines, m1=m2= -3/2.

Putting value of slope in equation (i)

\((y + 5) = \frac{ - 3}{2} (x - 5)\)

\(2(y + 5) = - 3(x - 5)\)

\(2y + 10 = - 3x + 15\)

\(3x + 2y - 5 = 0\)

Therefore the required equation is; 3x+2y-5=0.

By evaluating a linear equation, we will see that after two seconds there are 93 gallons of fuel.

We know that the tank initially has 103 galons of fuel, and we know that it releases 5 gallons per second at a constant rate.

So, after x seconds, the amount of fuel inside the container is:

F(x) = 103 - x*5

so we have a linear equation.

The amount of fuel in the tank after 2 seconds is given by:

F(2)=  103 - 2*5 = 103 - 10 = 93

After 2 seconds there are 93 gallons of fuel.

There is only one way 345 can be written as the sum of an increasing sequence of two or more consecutive positive integers. The correct answer is A) 1.

To find the number of ways 345 can be written as the sum of an increasing sequence of two or more consecutive positive integers, we need to consider the factors of 345.

First, let's find the prime factorization of 345: 345 = 3 * 5 * 23.

Now, let's focus on factor 23. Since the sequence needs to have at least two consecutive positive integers, the smallest possible sequence would be 23 and 24. We can see that any larger sequence would have a sum greater than 345.

Therefore, the only possible way to write 345 as the sum of an increasing sequence of two or more consecutive positive integers is 23 + 24.

Hence, the answer is option (a) 1.
