The statement which correct describe "confidence-interval" is (d) confidence level is considered as probability that something will fall within "confidence-interval".

A "Confidence-Interval" is a statistical term used to describe the amount of uncertainty associated with a sample estimate. It refers to the percentage of all possible samples that can be expected to include the true population parameter being estimated.

For example, if a study reports a 95% confidence level, it means that 95% of all possible samples would contain the true population parameter. This can be considered as the probability that the estimate falls within a certain range or interval, called the confidence interval.

Therefore, option (d) is the correct statement.

Answer: 5 and 2

Step-by-step explanation:

In an arithmetic sequence, the difference between consecutive terms is constant. Since the third and fourth terms are -1 and -4, the common difference is -4 - (-1) = -3. Therefore, the second term is -1 - (-3) = 2 and the first term is 2 - (-3) = 5. So the first and second terms of the sequence are 5 and 2 respectively.

Answer:

The answer is (3) 0.015.

Step-by-step explanation:

This is because to find the probability of finding both independent events happening at the same time, we must multiply them.

The independent events are:

- Randomly selecting a defective battery: 0.02

- Raining tomorrow: 0.75

0.02 x 0.75 = 0.015

Therefore, the answer is (3) 0.015.

The height of the person that cast a shadow of 1.5 foot is 6 foot.

When the sun is at a certain angle in the sky, a 100 foot building will cast a 25 foot shadow. A person cast a shadow of 1.5 foot at the same time.

Therefore, the height of the person can be found by setting up a proportional relationship between the length of shadow and the actual height of the building and person.

Hence,

let

x = height of the person

Therefore,

100 / 25 = x / 1.5

cross multiply

25x = 100 × 1.5

25x = 150

divide both sides of the equation by 25

x = 150 / 25

x = 6

Therefore,

height of the person  = 6 foot.

Answer:

The market trader should sell each of the remaining 20 packs of muffins for £1.30 to meet his target.

Step-by-step explanation:

To find out how much the market trader needs to sell the remaining 20 packs of muffins, we first need to calculate his total cost and his target revenue.

The cost of the loaves of bread is:

100 loaves x 84p/loaf = £84

The cost of the packs of muffins is:

60 packs x £1.10/pack = £66

Therefore, the total cost for the trader is:

£84 + £66 = £150

To make a 40% profit, the trader needs to make £150 x 40/100 = £60 in profit.

His target revenue is, therefore:

£150 + £60 = £210

The revenue from the loaves of bread is:

100 loaves x £1.20/loaf = £120

The revenue from the 40 packs of muffins sold at £1.60 per pack is:

40 packs x £1.60/pack = £64

So the total revenue from the loaves of bread and the 40 packs of muffins is:

£120 + £64 = £184

This means that the trader needs to make:

£210 - £184 = £26

from the sale of the remaining 20 packs of muffins.

To sell 20 packs of muffins to make £26, he needs to sell each pack for:

£26/20 = £1.30 per pack

Therefore, the market trader should sell each of the remaining 20 packs of muffins for £1.30 to meet his target.

He will need to use the wheelbarrow at least 41 times to fill the delivery truck to 70% of its capacity.

Volume is a measure of the amount of space that a substance or object occupies in three dimensions. It is typically measured in units such as cubic meters (m³), cubic centimeters (cm³), liters (L), or gallons (gal), depending on the system of measurement being used.

First, let's calculate the total volume of the delivery truck:

Volume of delivery truck = length x width x height

Volume of delivery truck = 11 ft x 8 ft x 6 ft

Volume of delivery truck = 528 cubic feet

To fill the delivery truck to 70% of its capacity, Johnny needs to put 0.7 x 528 = 369.6 cubic feet of planting soil in the truck.

Now, let's calculate the volume of planting soil that fits in the wheelbarrow:

Volume of wheelbarrow = length x width x height

Volume of wheelbarrow = 2 ft x 3 ft x 1.5 ft

Volume of wheelbarrow = 9 cubic feet

Number of loads = Total volume of planting soil needed / Volume of each load

Number of loads = 369.6 cubic feet / 9 cubic feet

Number of loads = 41.0666667

Since Johnny cannot use a fraction of a load, he will need to use the wheelbarrow at least 41 times to fill the delivery truck to 70% of its capacity.

The correct interpretation of the p-value is 3.34.

We are given that;

t-value=3.34

Number of customers= 200

Now,

The p-value is the probability of obtaining a test statistic as extreme or more extreme than the observed one, assuming that the null hypothesis is true. In this case, the p-value of 0.001 means that there is a 0.1% chance of getting a t-value of 3.34 or higher (or -3.34 or lower) if the true slope of the linear relationship between the two ratings is zero. The p-value is very small, which indicates that the data provide strong evidence against the null hypothesis and in favor of the alternative hypothesis.

The p-value of 0.001 means that there is a 0.1% chance of getting a t-value of 3.34 or higher (or -3.34 or lower) if there is no linear relationship between the two ratings.

Let the number of twin births in 2000 be x.

According to the problem, the number of twin births in 2015 increased by 14%, which means the number of twin births in 2015 is:

x + 0.14x = 1.14x

We also know that the number of twin births in 2015 is approximately 133,950, so we can set up the following equation:

1.14x = 133,950

Solving for x, we get:

x = 117,500

Therefore, there were approximately 117,500 twin births in 2000.

The cost of ending inventory using the weighted-average method is $198.24.

An ending inventory is often derived by adding new purchases to beginning inventory and then subtracting the cost of goods sold.

To calculate it using the weighted-average, we must compute the weighted average cost per unit and then multiply the weighted average cost per unit by the number of units in ending inventory to get the cost of ending inventory.

The total cost of goods available for sale is:

= (4 x 1.50) + (11 x 2.00) + (11 x 2.50) + (16 x 2.75) + (17 x 3.50) + (21 x 3.70) + (31 x 3.90) + (17 x 4.30)

= $430.7

The total units available for sale is:

= 4 + 11 + 11 + 16 + 17 + 21 + 31 + 17

= 128

The weighted average cost per unit is:

= $430.70 / 128 units

= $3.36484375

= $3.36

The cost of ending inventory will be:

= 59 units x $3.36

= $198.24

The solutions to this quadratic equation are x = √(73/3) + 5 or x = -√(73/3) + 5.

In Mathematics and Geometry, the standard form of a quadratic equation is represented by the following equation;

ax² + bx + c = 0

Next, we would solve the given quadratic equation by using the completing the square method;

3x² - 30x = -2

By dividing all through by 3, we have:

x² - 10x = -2/3

In order to complete the square, we would have to add (half the coefficient of the x-term)² to both sides of the quadratic equation as follows:

x² - 10x + (-10/2)² = -2/3 + (-10/2)²

x² - 10x + 25 = -2/3 + 25

x² - 10x + 25 = 73/3

By simplifying, we have;

(x - 5)² = 73/3
