The following scatter plot represents the number of views a video gets each day.

N76 [4]

Answer:

y = 1.0535(4.9512)^x

It can be considered a viral video

Step-by-step explanation:

Using the exponential regression calculator, the regression model obtained is :

y = 1.0535(4.9512)^x

Using the model, we can determine if a video can be considered viral ;

Number of days, x = 10

y = 1.0535(4.9512)^10

y = 1.0535(8853290.1338)

y = 9,326,941.15

Hence, video will receive way over 3 million reviews, a review of about 9,326,941, hence, it can be considered a viral video.

Elis [28]

Answer:

Sum of their present ages = 20 years

Step-by-step explanation:

Present age :

Neha's age = x years

Reemas' age = x - 4

After 5 years:

Neha's age = (x +5) years

Reemas' age = (x - 4 + 5 ) = x + 1

Sum of the ages of Reema and Neha will be 30

Therefore,

x + 5 + x + 1 = 30

x + x + 5 + 1 = 30

2x + 6 = 30

2x = 30 - 6

2x = 24

x = 24/2

x = 12

Neha's age = 12 years

Reema's age = 12 - 4 = 8 years

Sum of their present ages = 12 + 8 = 20 years

What is the area of a rectangle of 5/9 m in length and 7/8 m in width

Andru [333]

Answer:

35/72 $m^2$

Step-by-step explanation:

Rectangle Formula: $l*w=Area$

Switch the variables with the numbers given:

$\frac{5}{9} *\frac{7}{8} =Area$

Multiply the top and bottom:

5*7 = 35

9*8 = 72

35/72 = Area

150g of roquefort cheese cost £1.68<br> work out the cost of 250g of roquefort

mafiozo [28]

ANSWER

250g of Roquefort cheese will cost

£2.8

EXPLANATION

If 150g of roquefort cheese cost £1.68, we can write the ratio,

$150: 1.68$

Let 250g of Roquefort cheese cost £x.

Then we can again write the ratio,

$250:x$

We can equate the two ratios and solve for x.

$150: 1.68 = 250:x$

We rewrite the ratios as fractions to obtain,

$\frac{150}{1.68} = \frac{250}{x}$

We cross multiply to get,

$150x = 250 \times 1.68$
This implies that,

$150x = 420$

Divide both sides by 150 to get,

$x = \frac{420}{150}$
$x = 2.8$

Therefore 250g of Roquefort cheese will cost

£2.8
