What is the Surface Area of the Triangular Prism below?

Mathematics
1 answer:
Firdavs [7]4 years ago
4 0

Answer:

c ) 2480 cm²

Step-by-step explanation:

Surface Area of a Triangular prism =

S = bh + lb + 2ls

b = 30cm

h = 8cm

s = 17 cm

l = 35cm

The surface area = 30cm × 8 cm + 35 × 30 cm + 2(35 × 17)

= 240 cm² + 1050 cm² + 1190 cm²

= 2480 cm²

Option c is the correct option

Adecco Workplace Insights Survey sampled men and women workers and asked if they expected to get a raise or promotion this year
Mumz [18]

Answer:

Yes

Step-by-step explanation:

Let p1 represent proportion of women and p2 proportion of men. The null and alternative hypothesis will be as follows

Null hypothesis

H_o=p2-p1 ≤0

Alternative hypothesis

H_a=p2-p1>0

Sample proportion of women, p1=74/200=0.37

Sample proportion of men is p2=104/200=0.52

Level of significance is 0.01

Pooled proportion=\frac {104+74}{200+200}=0.445

Test statistic

z=\frac {(0.52-0.37)-0}{0.445(1-0.445)*\sqrt{(1/200+1/200)}}=6.9124

p-value=P(Z≥z)=P(Z≥6.9124)=P(Z≤-6.9124)=0

Since the value of p is less than 0.01, we reject null hypothesis. There’s sufficient evidence that a greater proportion of men is expecting to get a raise

A sample of 32 people yielded the information about their health insurance in the given table.Two people who provided informatio
DochEvi [55]

From the table given

17 people have managed care plan

9 have Traditional insurance

6 have no insurance

The probability of an event happening is given as the ratio of the number of the possible outcome divided by the total outcome.

If two balls are taken, the probability that at least one has traditional insurance

TN or TM or TT or NT or MT

where T is for traditional insurance

N is for no insurance

M is for managed insurance

the probability that at least one of two people picked without replacement has traditional insurance

= 9/32 * 6/31 + 9/32 * 17/31 + 9/32 * 8/31 + 6/32 * 9/31 + 17/32 * 9/31

= (54 + 153 + 72 + 54 + 153)/992

= 486/992

= 243/496
