The option that best describes the experiment is accurate and reproducible.

<h3>What option describes the data?</h3>

All the values from the experiment are close in value to the accepted value. This indicates that the experiment is accurate. Two experiments yield the same values. This indicates that the experiment is reproducible.

Here is the table used in answering the question:

Accepted Value: 130

Experiment 1 129

Experiment 2 131

Experiment 3 129

Experiment 4 132

Identify the area of the rhombus. PLEASE HELP! I'm desperate!!

Naddika [18.5K]

Area = 1/2(diagonal) * √4*side^2 - diagonal^2

Area = 1/2(16)*√(4*17^2 - 16^2)

Area = 8 * √(4*289-256)

Area = 8 *√900

Area = 8 * 30

Area = 240 m^2

A random sample of pickles in a jar has the following weights in grams: 68, 54, 59, 70, 69, 65, 73, 59, 74, and 54

gogolik [260]

68 + 54 + 59 + 70 + 69 + 65 + 73 + 59 + 74 + 54 = 586 grams
586 grams/10 = 58.6 grams (if you round it, you will get 59 grams)

hope this helps!!

The line plot shows the weights of packages of meat available at a grocery store. The 3 lightest packages cost $4.40 per pound.

Mnenie [13.5K]

Answer:

$42.40

Step-by-step explanation:

The horizontal axis is in fractions.

The three lightest are two $\frac{5}{8}$ pounds & one $\frac{6}{8}$ pounds. Each cost $4.40 per pound.

So cost = 4.40(5/8+5/8+6/8) = $8.8

Remaining costs 4.80 per pound. We add up the remaining and multiply by 4.80 to get their cost.

cost = $4.80(1+1\frac{1}{8}+1\frac{1}{8}+1\frac{1}{8}+1\frac{2}{8}+1\frac{3}{8})=33.6$

Hence, total cost = 8.8 + 33.6 = $42.40

What is the halflife

blagie [28]

To model half-life, use the formula $A(t)=A_0 (\dfrac{1}{2})^{ \frac{t}{t_{1/2}}$ . Here, $A(t)$ is the amount remaining after a length of time $t$ . $A_0$ is the amount that you start with. $t_{1/2}$ is the half-life. You plug in 50 for $t_{1/2}$ , 10 for $A_0$ , and 25 for $t$ . You get $A(t)=10( \frac{1}{2})^{25/50} = 10( \frac{1}{2})^{1/2} = 7.07 \ grams$ .
