Answer:

the twins will always have the same age

Step-by-step explanation:

the equation for jasmine's age is 2(3x+6), while the equation for james's age is 3(2x+4)

2(3x+6) = 2*3x + 2*6 = 6x + 12

3(2x+4) = 3*2x + 3*4 = 6x + 12

since both have the same equation, both will be the same age when you plug in the same x value

kotegsom [21]

Answer: 7 crayons

Step-by-step explanation:

To solve we first must find the total number of crayons available by adding up how many crayons are in each container.

         56+12+96 = 160 crayons total

Next we take this number and divide it by 22 (the number of students in the class) to determine how many crayon each student gets

         160 crayons/22 students = 7.272727 crayons per student

However, it's important to note that this number is not a whole number. We must then round down to the nearest whole number because students aren't given fractions of crayons.

         7.272727 ==> 7 crayons per student

Jamie is trying to work out the surface area of the cuboid below. Spot any mistakes and write the correct answer.
umka21 [38]

Step-by-step explanation:

The dimensions of the cuboid are 5 cm, 7 cm and 9 cm.

The formula for the surface area of the cuboid is as follows :

A=2(lb+bh+hl)

We have,

b = 9 cm, l = 7 cm and h = 5 cm

So,

A=2(9\times 7+9\times 5+7\times 5)\\\\A=2\times 143\\\\A=286\ cm^2

Jamie forgets to multiply 143 by 2 as the formula for surface area contains 2 as well.

liberstina [14]

Answer: 0.0516

Step-by-step explanation:

Given : The number of defective components produced by a certain process in one day has a Poisson distribution with a mean of \lambda=20.

The probability mass function for Poisson distribution:-P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}

For x= 15 and  \lambda=20 , we have

P(X=x)=\dfrac{e^{-20}(20)^{15}}{15!}=0.0516488535318\approx0.0516

Hence, the probability that exactly 15 defective components are produced in a particular day = 0.0516
