Jay organised a large wedding and 1/3 of them chose beef 5/12 of them chose Chicken and 69 of them chose vegetarian so how many

DerKrebs [107]

Answer:

276 Guests

Step-by-step explanation:

Calculation to determine how many guest were at the wedding

Guests that choose beef =1/3

Guests that choose chicken= 5/12

Guests that choose vegetarian=69

Now let calculate the how many guest were at the wedding

Let x represent the numbers of guest that were present at the wedding

Hence,

x/3 + 5x/12 + 69 = x

9x/12 + 69 = x

12x/12 - 9x/12 = 69

3x/12 = 69

x/4 = 69

x=69*4

x = 276 guests

Therefore the numbers of guests that were at the wedding is 276

Answer:

59°

Step-by-step explanation:

In triangle DAB, by Pythagoras theorem:

$DB= \sqrt {6^2 +5^2} =\sqrt{36+25}=\sqrt{61}$

Next, in triangle DCB, by Pythagoras theorem:

$DB= \sqrt {(\sqrt {61} )^2 - 4^2} =\sqrt{61-16}=\sqrt{45}$

Now, by sin rule.

$\frac{ \sin \: p}{ \sqrt{45} } = \frac{ \sin 90 \degree}{ \sqrt{61} } \\ \\ \frac{ \sin \: p}{ 6.70820393} = \frac{ 1}{ 7.81024968 } \\ \\ \sin \: p = \frac{ 6.70820393}{7.81024968} \\ \\ \sin \: p = 0.858897501 \\ \\p = 59.19301883 \degree \\ \\ p \approx 59 \degree$

A grocery supplier believes that in a dozen eggs, the mean number of broken eggs is 0.6 eggs with a standard deviation of 0.3 eg

serg [7]

Answer:

(a) 1.8 eggs

(b) 0.52 eggs

Step-by-step explanation:

According to the problem, computation of the given data are as follows:

The mean number of broken eggs in a dozen E(X) = 0.6

Standard deviation SD(X) = 0.3

(a). For 3 dozen eggs, number of broken eggs can be calculated by using following formula,

E(X) for 3 dozen = 3 × 0.6

= 1.8 eggs

(b). Standard deviation for 3 dozen can be calculated as follows,

SD (X) = × $\sqrt{3* (0.3)^{2}$

= $\sqrt{27}$ $\sqrt{27}$

= 0.52 eggs

Sarah went to the grocery store and bought bottles of soda and bottles of juice. Each

kow [346]

Answer:

5 numbers of soda bottles and 10 numbers of juice bottle was purchased.

Step-by-step explanation:

Let Sarah purchased x bottles of Soda and y bottles of Juice.

Each soda bottle contains 45 gm of sugar and each juice bottle contains 30 gm of sugar, and there is a total of 525 gm of sugar,

Hence, we can write 45x + 30y = 525, ⇒ 3x + 2y = 35 ...... (1)

Now, it is given that, she purchased 5 more bottles of juice than bottles of soda.

Hence, x + 5 = y, ⇒ x - y = - 5 ......... (2)

Now, solving equations (1) and (2) we get, 5x = 25, ⇒ x = 5

Hence,from equation (2), y = x + 5 = 10

Therefore, 5 numbers of soda bottles and 10 numbers of juice bottle was purchased. (Answer)
