Diego has 200 students in his grade which is 2 times as many as Lin. Lin’s grade has x students. Write this equation.
ILL GIVE BRAINLEIST FAST PLZ 15 POINTS
Answer:
200 ÷ 2 = x
Step-by-step explanation:
Diego has 2 times as many a Lin. That means to find Lin's student number, we would have to split 200 in half.

A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. The company wishes to test the hypothesis against using a random sample of specimens. Calculate the P-value if the observed statistic is . Suppose that the distribution of the sample mean is approximately normal.
Complete question :
A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. The company wishes to test the hypothesis H0 : μ = 12 against H1 : μ < 12 using a random sample of n = 4 specimens. Calculate the P-value if the observed statistic is xbar = 11.5. Suppose that the distribution of the sample mean is approximately normal.
Answer:
0.02275
Step-by-step explanation:
Given :
Population mean μ = 12
Standard deviation, σ = 0.5
Sample size, n = 4
Observed statistic, xbar = 11.5
H0 : μ = 12
H1 : μ < 12
The test statistic = (xbar - μ) ÷ σ/sqrt(n)
Test statistic =. (11.5 - 12) ÷ 0.5/sqrt(4)
Test statistic = - 0.5 ÷ 0.5/2
Teat statistic = - 0.5 / 0.25 = - 2
Since, it is stated that, distribution is approximately normal ; then we can use the Z distribution and obtain our Pvalue.
We could obtain P value using the Pvalue Z distribution calculator at α = 0.05, 1 - tail
Pvalue = 0.02275
Or
P(x < - 2) = 0.02275 (Z distribution table)
Two hundred forty and twenty-five hundredths in standard form

step-by-step explanation:
look at what it says about the number and then decidetwo hundred forty - - > 240
the number sounds just like what it saystwenty-five hundredths - - > .25
the numbers would be after the decimal since it is "hundredths"Factor the following: 28 W + 12J

Cami buys 4 pounds of ground beef for $22. The total cost in dollars, y, is proportional to the number of pounds purchased, x pounds ground beef y=what.
Answer:
88
Step-by-step explanation:
The total cost of y 4 pounds of ground beef which is bought by Cami at the rate of $22 per pound of ground beef is $88.
What is the total cost?Total cost or the final cost is the summation of all the cost spend while buying any good or taking any service.
Cami buys 4 pounds of ground beef for $22. The total cost in dollars, y, is proportional to the number of pounds purchased, x pounds ground beef.
In this problem, the total cost y has to be found out. As the price of one pound of ground beef is $22 and there is total 4 pounds of ground beef, Cami bought.
Thus, the total cost is,
[tex]y=22\times44\\y=88[/tex]
Thus, the total cost of y 4 pounds of ground beef which is bought by Cami at the rate of $22 per pound of ground beef is $88.

In circle B with the measure of minor arc AC= 84°, find m
Answer:
m<ADC = 42°
Step-by-step explanation:
Based on the inscribed angle theorem, the inscribed angle, m<ADC is ½ the measure of minor arc AC.
If minor arc is given as 84°, therefore:
m<ADC = ½(84)
m<ADC = 42°
Find the Area of the figure below, composed of a rectangle and a semicircle. Round to
the nearest tenths place.
10
6
Can somebody please help me
Answer:
Area = 74.1 square units
Step-by-step explanation:
Area of the composite figure = Area of the rectangle + Area of the semicircle
Area o the rectangle = Length × Width
= 10 × 6
= 60 square units
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
Here, r = radius of the semicircle
For the semicircle with radius = [tex]\frac{6}{2}[/tex] = 3 units
Area = [tex]\frac{1}{2}\pi (3)^{2}[/tex]
= 4.5π
= 14.14 units²
Total area of the composite figure = 60 + 14.14
= 74.14 square units ≈ 74.1 square units

Water is flowing from Tank #1 to Tank #2 as shown in the picture. Originally, Tank #1 had 1,540 gallons in it and Tank 2 had 236 gallons in it. Water is draining out of Tank #1 at a ate of 6 gallons per minute and, thus, filling Tank #2 up at a ate of 6 gallons per minute. ) Write an equation for each tank that models the volume of water, v in gallons, as a function of the number of minutes, m, that the water has been flowing. Tank #1: Tank #2: Find out how long it takes, to the nearest minute, for the two tanks to have Will it take longer or shorter than 2 hours? Justify.
Answer:
Melody, think about this as below
Step-by-step explanation:
when does tank 1 = tank 2 when there is 6 gpm
tank 1 = 1540
tank2 = 236
1540-6x = 236 +6 x
1304 = 12x
108 [tex]\frac{2}{3}[/tex] = x
6*108 [tex]\frac{2}{3}[/tex] = 652 gallons
236+652=888
1504-652=888
in 108 [tex]\frac{2}{3}[/tex] minutes the tanks become equal with 888 gallons each :)
