Answer:

68.6

Step-by-step explanation:

Given the initial ratio of 24 points out of 35 possible points, you can set up a proportion (equivalent ratios) to find the expected number of points math students would ear on a test of 100 possible points:

\frac{earned}{possible}=\frac{24}{35}=\frac{x}{100}

Where 'x' is the number of points earned on the 100 point test.

Cross-multiply: 35x = 24(100) or 35x = 2400

Divide both sides by 35: 35x/35 = 2400/35

Solve for x:  x = 68.6

Alona [7]

500 at 40 each = £20000

To make a profit he needs to make more than £20000

20 broke so he sold 500-20 = 480 at 45 each.

480 x 45 = 21600

His profit was £1,600

mel-nik [20]

Answer:

87

Step-by-step explanation:

Population standard deviation = σ = 37 grams

Confidence interval = 94%

(1-α)×100% = 94

⇒α = 0.06

From table z table and interpolation

z = 1.881

L = Confidence interval length = 15

N = Number of samples

L=2z_{\alpha/2}\frac{\sigma}{\sqrt N}\\\Rightarrow \sqrt N=2z_{\alpha/2}\frac{\sigma}{L}\\\Rightarrow \sqrt N=2\times 1.881\frac{37}{15}\\\Rightarrow \sqrt N=9.2796\\\Rightarrow N=86.11097616\approx 87

∴ Number of turtles must she must weigh is 87
