One hundred sixty people were surveyed and asked if they believed in UFOs, ghosts, and Bigfoot.

HACTEHA [7]

Answer:

Number of people surveyed believed in at least one of these things = 83

Step-by-step explanation:

Given,

Total number of people, n(T) = 160

number of people believe in UFOs, n(U) = 42

number of people believe in ghost, n(G) = 45

number of people believe in Bigfoot, n(B) =21

number of people believe in UFOs and ghost, n(U ∩ G) = 11

number of people believe in Bigfoot and ghost, n(B ∩ G) = 6

number of people believe in UFOs and Bigfoot, n(U ∩ B) = 4

number of people who believe in all, n(U ∩ G ∩ B) = 2

We have asked to draw the Venn diagram and to calculate the number people surveyed believed in at least one of these things .

So, according to Venn diagram,

Number of people surveyed believed in at least one of these things = 25+11+4+2+26+9+6 = 83

Number of people surveyed believed in at least one of these things = 83

When solving negative one over five (x − 25) = 7, what is the correct sequence of operations?

pshichka [43]

The system of equations below represents the measures of 2 angles created by the diagonal of a rectangle: x + y = 90 y = y equal

sukhopar [10]

Answer:

Greater angle=75° Smaller angle=15°

Step-by-step explanation:

Given expressions

x+y=90
y= $\frac{x}{5}$

⇒ $y=\frac{x}{5}\\ x=5\times y$

Substitute this in the first expression

⇒ x+y=90

$5\times y+ y=90\\6\times y =90\\y=\frac{90}{6} \\y=15$

From the First expression

Substitute y value to get x value

⇒ $x+y=90\\x+15=90\\x=75$

Therefore x=75 and y=15

⇒ Greater angle=75 and smaller angle=15

Which logarithmic function can be used to approximate the value of y in the equation 4^y=5?

spayn [35]

From the definition of logarithm, we know that:

$$a^y=b\quad\iff\quad y=\log_ab\qquad\quad \,\text{when }a,b\ \textgreater \ 0\,\,\text{ and }\,\,a\neq1$

In this case $a=4$ and $b=5$ so:

$$\boxed{y=\log_45}$
