Answer: 32.98^{\circ}

Step-by-step explanation:

Since, By the given diagram,

In quadrilateral ABCD, all angles are right angles ⇒ DC = AB = 15 cm and CB = DA

Also, In triangle DFA,

sin 56^{\circ} = \frac{DA}{DF}

⇒ sin 56^{\circ} = \frac{DA}{16}

⇒ 16\times sin 56^{\circ}=DA

⇒ 13.2646011609\text{ cm} = DA

Now, In triangle, DEC,

tan x = \frac{EC}{DC}

⇒ tan x = \frac{EB-CB}{DC}

⇒ tan x = \frac{EB-DA}{DC}

⇒ tan x = \frac{23-13.2646011609}{15}  

⇒ tanx = \frac{9.73539883912}{15}

⇒ tanx = 0.64902658927

⇒ x = 32.9846428556^{\circ} \approx 32.98^{\circ}

One jar filled with honey weighs 120 grams and one empty jar with half filled honey jar weighs 150 grams what is the weight of t
VMariaS [17]

Answer:

90 grams

Step-by-step explanation

Full = 120

half filled + empty = 150

half of 120 = 60

Therefore, a jar weighs 150 - 60

= 90 grams

Cans of frozen orange juice are weighed to ensure they are not underfilled. Cans are independent, and the probability that a can
olga2289 [7]

Answer: 0.999986176

Step-by-step explanation:

To solve this, the probability distribution formula for selection will be used

Where P(x=r) = nCr * p^r * q^n-r

To get the probability that all 3cans are not overfilled, since the probability of success given in the question is that of a can being overfilled, then we will first derive the probability of having exactly 3cans being overfilled and subtract this gotten answer from 1

n= 3, r=3, p=0.024, q=1-0.024=0.976

When, 3 cans are overfilled, P(x=3) becomes:

P(x=3) = 3C3 * 0.024^3 * 0.976^0

P(x=3) = 1 * 0.000013824 * 1

P(x=3) = 0.000013824.

Then, probability that all three cans are not overfilled becomes :

1 - 0.000013824. = 0.999986176,

True or False
Rama09 [41]

Answer:

True

Step-by-step explanation:

Permutation is act of arranging members of a set while combination is selection of the items from collection.

The number of permutation of r object out of n is:

^nP_r=\frac {n!}{(n-r)!}

The number of combinations of r object out of n is:

^nC_r=\frac {n!}{(n-r)!\times r!}

Or,  

^nC_r=\frac {^nP_r}{r!}

So, number of the permutations of r objects out of n is greater than number of the combinations of r objects out of n.
