A number X rounded to 2 decimal places is 7.42. Write down the error interval for X
Answers
Answer:
X = [7.415,7.419].
Step-by-step explanation:
The number is 7.42 so the thousandth place is from 5 to 9 and hundredth place is 1. i.e. 7.415, 7.416, 7.417, 7.418, 7.419. As 7.415 rounded to 2 decimal place is 7.42. The interval in x[7.415, 7.419].

Answer:
The answer is "Experimental Probability ".
Step-by-step explanation:
The probability of experiments is uncertainty which is calculated several times as per the outcome of even an experiment. The probability distribution is probably dependent upon reasoning. This probability is a price of about one or zero. It was based on the relative frequency or what occurs during a probability test.

Answers
Answer:
[tex]Balance = \$2.23[/tex]
Step-by-step explanation:
Given
[tex]Allowance = \$30[/tex]
[tex]Video\ Game = \$17.99[/tex]
[tex]Chocolate\ Bar = \$0.79[/tex]
[tex]Remote\ Car = \$8.99[/tex]
Required [Missing from the question]
What is his balance after purchasing the items
First, calculate total cost of items
[tex]Total =Video\ Game + Chocolate\ Bar + Remote\ Car[/tex]
[tex]Total = \$17.99 + \$0.79 + \$8.99[/tex]
[tex]Total = \$27.77[/tex]
The balance is then calculated as:
[tex]Balance = Allowance - Total[/tex]
[tex]Balance = \$30 - \$27.77[/tex]
[tex]Balance = \$2.23[/tex]

I would say A. as a best guess but the question is odd it does not add up to 101 students it adds up to 101 plus all of them are female juniors so they would be picked every time it would be 101/101

Step-by-step explanation:
Area of a rectangle is length x breadth

Step-by-step explanation:
A regular polygon is a shape with equal sides and angles. Because of this, we can write the following equation to set two sides equal to each other:
[tex]3a+b+3=2a+2b+6[/tex]
Solving, we will get a in terms of b:
[tex]3a=2a+b+3,\\a=b+3[/tex]
Now we can substitute a for (b+3) into our equation:
[tex]5a-2b+1=2a+2b+6,\\5(b+3)-2b+1=2(b+3)+2b+6,\\3b+16=4b+12,\\-b=-4,\\b=\boxed{4}[/tex]
Therefore, the length of each side of this polygon is [tex]5(4+3)-2(4)+1=28[/tex].
Since the perimeter of the polygon consists of all five sides, the perimeter is:
[tex]p=28\cdot 5 =\boxed{140}[/tex]
Set the 2 sides lengths equal to each other. Solve for the variables. Then add all sides together, plugging in the values of the variables. The bottom side is the same as the 2 top sides (bottom side X 3)

Step-by-step explanation:
Departmental Store Agora claims that their mean weekly sales of Aerosol were at most 2,400 packages over the past 6 months and population distribution is unknown. The manager wants to check if the sales have decreased in recent times. He obtained a random obtained sample of sales data from 61 stores and found that the sample mean is 3,593 packages with sample standard deviation 4919. At 7% significance level, using critical value approach see if the claim is true or not.
Answers
Answer:
There is enough statistical evidence to suggest that the department's claim is not true
Step-by-step explanation:
The mean weekly sales μ₀ ≤ 2,400 packages
The period over which the weekly sales were measured = Over the last 6 months
The number of stores in the sample, n = 61 stores
The sample mean, [tex]\overline x[/tex] = 3,593
The sample standard deviation, s = 4919
The significance level = 7% = 0.07
The critical value approach
The null hypothesis, H₀; μ ≤ μ₀
The alternative hypothesis, Hₐ; μ > μ₀
The test statistic is given as follows;
[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]
We get;
[tex]t=\dfrac{3,593-2,400}{\dfrac{4,919}{\sqrt{61}}} \approx 1.894[/tex]
With df = n - 1 = 61 - 1 = 60 at 7% significant level, from a graphing calculator the critical-t, = 1.495598
The p-value at the test statistic is between 0.01 and 0.005
Given that the p-value is less than the significant level, and the test statistic is larger than the critical-t we reject the null hypothesis, that the mean weekly aerosol sale is less than 2,400 packages.
Therefore, there is sufficient statistical evidence to suggest that the departments claim is not true and the mean sales of Aerosols have increased to more than 2,400 packages
Mr. Autry bought a hat for $99.90. He also bought a pair of boots for $89.90. What was the total cost of the hat and boots including an 8% sales tax
Answers
Answer:
$204.98
Step-by-step explanation:
Step 1: Add both item cost
[tex]99.90 + 89.90 = 189.80[/tex]
Step 2: Find the sales tax of the result
[tex]\frac{8}{100}\times 189.8 = 15.184[/tex]
Step 1: Convert 8% to fraction[tex]8\%= \frac{8}{100}[/tex]Simplify[tex]\frac{8}{100} = \frac{2}{25}[/tex]Step 2: Convert 189.80 to a fraction[tex]189.80 = \frac{189.8}{1}[/tex]Step 3: Set it up[tex]\frac{2}{25}\times \frac{189.8}{1}[/tex]Step 4: Cross divide[tex]189.80 \div 25 = 7.592\\2 \div 1 = 2[/tex]Step 5: Multiply the result[tex]7.592 \times 2 = 15.184[/tex]Step 3: Add the result from the total cost of both items

Un comerciante tiene 1108 cajas de zapatos y los quiere guardar en el cajon de su camion. Para saber si caben todas las cajas el coloca 20 a lo largo,7 a lo ancho y 8 a lo alto ¿puede guardar todas las cajas de zapatos en el cajon?
Answers
Answer:
El comerciante NO PUEDE guardar todas las cajas de zapatos en el cajón
Step-by-step explanation:
Tenemos que encontrar el volumen de la caja.
Se nos dice en la pregunta que:
Coloca 20 a lo largo, 7 a lo ancho y 8 a la altura.
Volumen = Largo × Ancho × Alto
Largo = 20, Ancho = 7, Alto = 8
Volumen = 20 × 7 × 8
= 1120
También se nos dice que: el comerciante tiene 1108 cajas de zapatos y quiere guardarlas en el cajón de su camión.
Comparando esto con nuestro cálculo anterior, el comerciante NO PUEDE guardar todas las cajas de zapatos en el cajón
