Suppose that the delivery times of a nationwide pizza chain are normally distributed with an unknown mean and standard deviation. The delivery times of 26 randomly sampled pizza orders are used to estimate the mean delivery time for the population. What t-score should be used to find the 95% confidence interval for the population mean?
Answer:
The t-score to be used to find the 95% confidence interval for the population mean is;
[tex]t_{(0.025, \, 25)} = 2.06[/tex]
Step-by-step explanation:
The t-score which is representative of a point with n - k (n, and k represents the sample size and the number of groups in the test respectively) degrees of freedom from the Student's T-distribution is a standard test statistic obtained by applying a T-test
Therefore, the t-score used for a confidence interval is obtained by by making use of the the following information;
The number of degrees of freedom = n - k
The confidence level in the confidence interval
The parameters given in the question are;
The number of pizza orders in the sample, n = The sample size = 26
The number of samples used in the estimate, k = 1 group of 26 randomly sampled pizza
The level of confidence (the probability) that the interval contains the population mean = 95%
Therefore, the significance level, α = 1 - 95% = 1 - 95/100 = 0.05
∴ The α-level for the upper and lower limit of the interval are α/2 = 0.05/2 = 0.025 long
The degrees of freedom, df = n - k
∴ For the estimation, DF = 26 - 1 = 25
The t-statistic is therefore the t-value at the intersection of the row for DF = 25 and the 0.025 (one-tail) column (0.025 two-tail column) which gives;
[tex]t_{(\alpha /2, \, DF)} = t_{(0.025, \, 25)} = 2.06[/tex]

10 people take 8 days to build a wall.
How long will it take 4 people to do the same job?
Answer:
20 days
Step-by-step explanation:
10 to get to 4 needs to be divided by 2.5 so we do the opposite to the other side since with fewer people it would take longer. (2.5 times longer).
10/2.5 = 4
8x2.5 = 20 days
9/2 as a fraction and what is 2/3 reciprocal
Answer:
9/2 = 4 1/2 , 2/3 = 3/2
Step-by-step explanation:
The reciprocal of a fraction is switching the numerator and the denominator.
2/3, switched is 3/2.
To find the mixed form of an improper fraction, you divide the numerator by the denominator.
Like this, 9/2 = 4.5
4 is the whole.
So, 4 would be the whole number.
Then there is 1 left over.
You keep the denominator.
So it would be 4 1/2.
Geometry help please. Complete the similarity statement, in the box below, of these two triangles.
Answer:
ΔIJK ≈ ΔXVW
Step-by-step explanation:
Choose the set that is the possible side lengths of a right triangle.
a)1,1,2 b)3,5,9 c)3,4,7 d)1,1,square root2
Answer:
D
Step-by-step explanation:
Mathematically, for us to have a right triangle, Pythagoras’ theorem must be obeyed
From the theorem, the square of the hypotenuse (longest side) equals the sum of the squares of the two other sides
Let us take a look at the given set of numbers:
2 square is not same as 1 squared + 1 squared
9 squared is not equal to 3 squares + 5 squared
7 squared is not equal to 4 squared + 3 squared
But;
root 2 squared equals 1 squared plus 1 squared and that is our answer
Which function or functions have a slope equal to the slope of Function 1?
Answer:
function 2 only
Step-by-step explanation:
The Function that have a slope have 1 is Function 1.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
From function 1, the slope is
Slope = (0-2)/ (1- 3)
Slope = (-2)/ (-2)
Slope = 1
Now, for function 2 the slope is
Slope = 2
and, for Function 3 the slope is
Slope = 0
and, For function 4 the slope is
Slope = 3/2
Thus, Slope of function 1 have slope 1.

No desenvolvimento da multiplicação 2 × (4+7) = 2 × 4 + 2 × 7 = 8 + 14 = 22, qual propriedade fui utilizada?
Answer:
Propiedad distributiva de la multiplicación sobre la suma
Step-by-step explanation:
Spanish
Propiedad distributiva de la multiplicación sobre la suma
2 × (4 + 7)
Aquí vemos que el número 2 se multiplica por 4 y 7
2 se distribuye a 4 y 7
= 2 × 4 + 2 × 7
Después de la multiplicación se suman ambos
= 8 + 14 = 22
Esta propiedad se llama propiedad distributiva de la multiplicación sobre la suma.

No development of multiplication 2 × (4 + 7) = 2 × 4 + 2 × 7 = 8 + 14 = 22, which property was used?
Distributive property of multiplication over addition
2 × (4 + 7)
Here we see that the number 2 is multiplied with both 4 and 7
2 is distributed to both 4 and 7
= 2 × 4 + 2 × 7
After multiplication both are added
= 8 + 14 = 22
This property is called distributive property of multiplication over addition.

¿Qué altura tiene un poste que proyecta una sombra de 21 metros, al mismo tiempo que una persona de 1.75 metros de estatura lo observa y proyecta una sombra de 1.35 metros?
Respuesta:
27,22 metros
Explicación paso a paso:
Dado :
Sombra del poste = 21 metros
Altura de la persona = 1,75 metros
Sombra de la persona = 1,35 metros
Altura del poste =?
Usando la relación:
Altura de la persona / sombra de la persona = altura del poste / sombra del poste
1,75 / 1,35 = x / 21
Cruz multiplicar
1,35 * x = 1,75 * 21
x = (1,75 * 21) / 1,35
x = 27,22

What is the volume of the cargo area of the moving truck?
A. 696 cubic feet
B. 756 cubic feet
C. 824 cubic feet
D. 888 cubic feet
Answer:
888sq. ft
Step-by-step explanation:
Volume of a rectangular prism = length * width * height
For the given diagram
area of the truck = area of the bigger + area of smaller prism
area of the bigger prism = 6 * 9 * 16
area of the bigger prism = 864sq. ft
Area of smaller prism = 2 * 2 * 6
Area of smaller prism = 24 sq. ft
Area of the figure = 864 + 24
Area of the figure = 888sq. ft

To find the value of theta, we need to find do the acos of it
θ = acos(1/2)
θ = 60
and then you find sin(60)
sin(60) = 0.86602540378
