Answer:
Step-by-step explanation:
H0 : μ = 46300
H1 : μ > 46300
α = 0.05
df = n - 1 = 45 - 1 = 44
Critical value for a one tailed t-test(since population standard deviation is not given).
Tcritical = 1.30
The test statistic :(xbar - μ) ÷ (s/sqrt(n))
The test statistic, t= (47800-46300) ÷ (5600√45)
t = 1500
t = 1500 / 834.79871
t = 1.797
The decision region :
Reject H0: if t value > critical value
1. 797 > 1.30
Tvalue > critical value ; We reject H0
Hence, there is sufficient evidence to conclude that cost has increased.
does anyone know how to do this ??

Taylor drives 375 miles to get to his cousin's house. If the drive takes 15 hours, what is Taylor's rate of speed?
Answer:
25 mph
Step-by-step explanation:
The formula for speed is s = d/t.
s - speed
d - distance
t - time
For your problem, 375 mi is the distance and 15 hrs is the time. When you divide 375/15, you get an answer of 25. The unit of measure is miles per hour or mph. In the end, Taylor's speed is 25 mph. Hope this helps!!

- WILL MARK BRIANLISt
answer:
A, D, E
step-by-step explanation:
in order to find the range, you have subtract the smallest number from the largest number in the set of values you are givenA — 13 - 1 = 12
B — 15 - 7 = 8
C — 12 - 12 = 0
D — 28 - 16 = 12
E — 36 - 24 = 12
F — 29 - 25 = 4
i took each of the set of values and subtracted the smallest from the largest and got that A, D and E give me 12 for the rangeCual es la magnitud de la aceleración angular de una llanta de un automóvil que adquiere una velocidad angular de 350 rad/s en 2 segundos?
Respuesta:
175 rad / s²
Explicación paso a paso:
Dado que :
Velocidad angular final = 350 rad / s
Tiempo empleado = 2 segundos
La aceleración angular, a =?
Recordar ; la aceleración angular es igual a la carga en velocidad angular con el tiempo
(velocidad final - Velocidad inicial) / tiempo empleado
Velocidad inicial = 0 rad / s
Aceleración angular = (350 - 0) / 2 = 350/2
= 175 rad / s²

13. Whats the domain and range?
14. What’s the domain and range?
Answer:
See below
Step-by-step explanation:
13) Domain: x -> {-3,-2,-1,0,1,2}, Range: f(x) -> {5}
14) Notice how x can't be -4 as that will make the denominator 0. Therefore, your domain is (-∞,-4)U(-4,∞) and your range is [0,∞) since 0 is the lowest possible real y-value that satisfies the equation (recall that if y<0, you are unable to find the real square root of a real number)

Monica has 2 gallons of milk to make milkshakes. Each milkshake contains 1 cup of milk. There are 128 ounces in 1 gallon and 8 ounces in 1 cup.
How many cups of milk does Monica have to make milkshakes? .
Answer: 32 cups of milk
Step-by-step explanation:
The first thing to do is to convert the gallons of milk to milkshakes so that you are able to convert easier to cups.
There are 128 ounces in 1 gallon and Monica has 2 gallons. The amount of milk Monica has in ounces is:
= 128 * 2
= 256 ounces
Each cup is capable of holding 8 ounces and there are 256 ounces available so the number of cups of milk is:
= 256 / 8
= 32 cups of milk

What is the distance between points (3.3) and Wc-2, -3)
Round to the nearest tenth if necessary.
Answer:
7.81 u
Step-by-step explanation:
Given :-
Two points (3,3) and (-2,-3) is given to us.And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,
[tex]:\implies[/tex] D = √{(x2-x1)² + (y2-y1)²}
[tex]:\implies[/tex] D =√[ (3+2)² +(-3-3)²]
[tex]:\implies[/tex] D =√[ 5² +6²]
[tex]:\implies[/tex] D =√[ 25 +36]
[tex]:\implies[/tex] D = 61
[tex]:\implies[/tex] D = 7.81
Hence the distance between the two points is 7.81 units .(x - 5)(5x + 2) = 0 (please help)
Answer:
x=-5
