Answer: c

Step-by-step explanation:

u want to separate it into the two triangles and a rectangle. so the first marked triangle is the first part of the problem then it adds on the rectangle 6(12) then theres that other unmarked triangle because u can see the bottom is 14 when the top is 12 so u take the formula and fill in 1/2(6)(2). i hope this makes sense im bad at explaining things.

MrMuchimi

Answer:

<h3>87 feet</h3><h3>1. You can find the value of the vertex of the parabola as following: </h3><h3 /><h3 /><h3 /><h3>2. Substitute values: </h3><h3 /><h3>a=-16 </h3><h3 /><h3>b=70 </h3><h3 /><h3>Then: </h3><h3 /><h3> </h3><h3 /><h3 /><h3 /><h3>3. Substitute the value obtained into the equation given in the problem. Therefore, you obtain the following result: </h3><h3 /><h3 /><h3 /><h3>4. To the nearest foot: </h3><h3 /><h3>h=87 feet</h3>

The amount of water consumed each day by a healthy adult follows a normal distribution with a mean of 1.30 liters. A health camp

Rom4ik [11]

Answer:

H0: μ ≤ 1.30

H1: μ > 1.30

|Test statistic | > 1.833 ; Reject H0

Test statistic = 3.11

Yes

Pvalue = 0.006

Step-by-step explanation:

H0: μ ≤ 1.30

H1: μ > 1.30

Samples, X ; 1.36,1.35,1.33, 1.66, 1.58, 1.32, 1.38, 1.42, 1.90, 1.54

Xbar = 14.84 / 10 = 1.484

Standard deviation, s = 0.187 (calculator)

Decison rule :

|Test statistic | > TCritical ; reject H0

df = n - 1 = 10 - 1 = 9

Tcritical(0.05; 9) = 1.833

|Test statistic | > 1.833 ; Reject H0

Test statistic :

(xbar - μ) ÷ (s/√(n))

(1.484 - 1.30) ÷ (0.187/√(10))

0.184 / 0.0591345

Test statistic = 3.11

Since ;

|Test statistic | > TCritical ; We reject H0 and conclude that water consumption has increased

Pvalue estimate using the Pvalue calculator :

Pvalue = 0.006
