Answer:

0.345

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

n = 5, r = 2, p = 0.41, and q = 0.59.

P = ₅C₂ (0.41)² (0.59)⁵⁻²

P = 0.345

Find the measure of angle A

blagie [28]

Answer:

43°

Step-by-step explanation:

(x + 53)° + (x + 74)° + 73° = 180°

(x + 53 + x + 74)° = 180° - 73°

(2x + 127)° = 107°

2x + 127 = 107

2x = 107 - 127

2x = - 20

x = - 20/2

x = - 10

$m\angle A = (x +53)\degree \\\\m\angle A = (-10 +53)\degree \\\\m\angle A = 43\degree \\\\$

A science teacher wants to prepare a resource pack for each of the 120 pupils in year 10. She will need to photocopy 40 pages pe

Tresset [83]

Answer:

She would save £5

Step-by-step explanation:

→ First work out the cost of items for one student. Work out cost of the photocopying

40 × £0.02 = £0.80

→ Add the cost of the one folder

£0.80 + £0.70 = £1.50

⇒ Now we know £1.50 is the amount of money it costs for one student, we multiply that by 120 because there are 120 pupils

£1.50 × 120 = £180

→ £180 is the total cost and now we minus that from the online price of £175

£180 - £175 = £5
