Mathematics
1 answer:
frozen [14]3 years ago
5 0
<span>1. The problem says that the is ratio 1:3:5 by weight and Talil wants to make 180 kg of concrete mix.

 2. Therefore, you have:

 1+3+5=9

 180 kg/9=20 kg

 3. Each of the 9 parts of the ratio weights 20 kg. So, to make 180 kg of concrete mix, he needs:

 1x20 kg=20 kg of cement
 3x20 kg=60 kg of sand
 5x20 kg=100 kg of gravel

 4. Talil has:

 15kg of cement (Not enough)
 85kg of sand (More than enough)
 100kg of gravel (Enough)
</span><span>
 Does Talil have enough cement , sand and gravel to make concrete mix?
</span><span>
 The answer is: No, she does no have </span>enough cement , sand and gravel to make concrete mix.

<span>Traveled Downstream a distance of 33 Mi and then came right back. If the speed of the current was 12 mph and the total trip took 3 hours and 40 minutes.
Let S = boat speed in still water then                                                                         (s + 12) = downstream speed                                                                                  (s -12) =  upstream speed 
     Given Time = 3 hours 40 minutes = 220 minutes   = (220/60) h = (11/3) h                      Time = Distance/Speed
                  33/(s +12) + 33/(s-12) = 11/3                                                                               3{33(s-12) + 33(s +12)} = 11(s+12) (s -12)                                                          99(s -12 + s + 12) = 11(</span> s^{2} + 12 s -12 s -144)                                                   99(2 s) = 11(s^{2} -144)                                                                                        198 s/11 = (s^{2} -144)                                                                                         18 s = (s^{2} -144)                                                                                            (s^{2} - 18 s - 144) = 0                                                                                         s^{2} - 24 s + 6 s -144 =0                                                                                       s(s- 24) + 6(s -24) =0                                                                                            (s -24) (s + 6) = 0                                                                                                  s -24 = 0, s + 6 =0                                                                                                s = 24, s = -6                                                                     Answer) s = 24 mph is the average speed of the boat relative to the water.

KonstantinChe [14]

Answer:

We don't have sufficient evidence to support the claim

Step-by-step explanation:

Null hypothesis:

H_0: p = 0.276

Alternate hypothesis:

H_1: p < 0.276

The P-value is 0.3064

0.3064 probability of finding a sample proportion lower than the one found.

The p-value is higher than the significance level of 0.05, which means that there is no sufficient evidence to support the claim.
